ZYTO Scan & Treatment Reviews: The Good, The Bad & The Ugly

Are ZYTO scans useful? Do ZYTO treatments work? Here we independently review ZYTO – the Good, the Bad, and the Ugly. Bioset, EAV, EDS, AMA, & Qest4 (ASYRA) are also compared to ZYTO. Included are tips for interpreting scan results and finding a good practitioner. Our ZYTO opinions and experiences are based on approximately 61 ZYTO scans and treatments over 4 years on our family of four. We do not work for, receive commission from, or monetize referral links for ZYTO or any of the other products referenced on this site.

Overview of Our History with Biocommunication Devices

Biocommunication refers to the general category of computerized devices that ‘scan’ and ‘treat’ the body. One practitioner called the computer software and associated devices ASYRA and Bioset, the other practitioner had a completely different setup and referred to it as Bioset. Dr. Simon Yu MD also does a ZYTO scan during intake in his practice, but he complains that it is not very accurate. He prefers Acupuncture Meridian Assessment (AMA) [1]. Note that ZYTO scans, Qest4 (ASYRA), and AMA are not FDA approved as medical devices. This doesn’t mean that they aren’t useful!

We started using biocommunication practitioners because we heard that they might be able to help us with allergies. Our experience with the first two Bioset and ASYRA practitioners was mixed, and it was hard for me to tell if any of the treatments were helping or not…. Until one Bioset practitioner treated my oldest daughter for sugar allergies and she turned into a monster. The details can be found on Yelp. Suffice it to say that a ZYTO practitioner was able to undo the monster. Immediately. It was then that I realized that biocommunication actually does something. I also learned that we don’t fully understand how it works. It seemed essential to find a good practitioner.

Overall our experience with ZYTO has been quite positive. Since the original writing of this article, ZYTO has gotten rid of their stand-alone treatment laser. They have also gotten rid of the ‘tower,’ which allowed practitioners and patients to scan in their own supplements. These were two of the most useful features of ZYTO! Had our family started ZYTO at this point in time, without those features, I’m not sure the experience would be so positive. In the rest of the content, I have tried to highlight features that do not depend on either of these two.

 
There are things that ZYTO is good at and things that it isn’t so good at. ZYTO scans these days can include more than just allergies, and it can be confusing what’s real and what’s not real, what’s accurate and what’s not accurate. It has taken me many years to discern what information is useful from a ZYTO scan. This information summarizes our family’s four years of experience as ZYTO patients. We typically went to our ZYTO practitioner about once every 4-6 weeks during this time. We went more often if we had any symptoms. Our opinions are based on a total of about 61 ZYTO scans and treatments, which is about $9,000 in practitioner bills.

Bioset, EAV, AMA & ASYRA / Qest4 Reviews

Bioset, EAV, AMA and ASYRA are older biocommunication feedback devices. We have tried them all, over multiple years and multiple practitioners. Some of them we also learned to do at home. The following sections give a brief summary of the strengths and weaknesses of each technology.
 

Bioset

Bioset varies a lot by practitioner. I have seen it done completely by a machine and sometimes partially with a practitioner involved in the treatment. Some practitioners use little physical glass vials of ‘stressors’, some use only a computer model of the stressors. Bioset is good at treating allergies if the correct stressor can be found and if the drainage pathways are open.
 

EAV, EDS & AMA

EAV was one of the first biocommunication feedback devices developed. It is often also called EDS. Dr. Simon Yu has a simplified, modified version of EAV called AMA. These techniques have the strength of being able to find the root causes of many health symptoms.
 

ASYRA and Qest4

ASYRA and Qest4 are technically also forms of EAV. However, the strengths and weaknesses are different enough to warrant a separate section. Note that ASYRA got in trouble with the FDA and recently re-branded as Qest4. My understanding is that the system is essentially the same. In the table below, the words ASYRA and Qest4 are used interchangeably.
 

ZYTO Scan: The Good

ZYTO scans are very good at some things. In my experience, ZYTO is great at:
 

1. Clearing Environmental Allergies – I used to be allergic to grass, and had to shut all windows before my husband mowed the grass. Now I mow the grass myself and love sitting in the grass. My seasonal springtime tree & pollen allergies are gone as well. My allergies came back every year until I healed my leaky gut. More and more research is pointing to the gut as the root cause of allergies [2, 3]. My ZYTO allergy clearings started permanently lasting after I healed my leaky gut and ate a diet conducive to keeping the gut healthy. NOTE: ZYTO may not be as good at allergy treatments now that they have gotten rid of their stand-alone laser. If anyone has any experience or comments, please write in on the contact page. Our family was treated for allergies with the stand alone laser only.
2. Opening Detox & Drainage Pathways – ZYTO is great at opening up drainage and detox pathways. If we’re having a Herxheimer reaction that I can’t figure out, then I go to ZYTO. Headaches and bad moods can sometimes be detox pathway issues as well. NOTE: ZYTO may not be as good at detox and drainage treatments now that they have gotten rid of their stand-alone laser.
3. Monitoring & Fixing Detox Organ Functions before they break, especially the liver & kidney. This is related to #2. ZYTO can catch and fix issues before they become problems that cause symptoms. NOTE: ZYTO may not be as good at organ pathway treatments now that they have gotten rid of their stand-alone laser.
4. Mineral & Vitamin Deficiencies – ZYTO often finds our vitamin & mineral deficiencies before they become an issue. This is especially useful to monitor during chelation. ZYTO scans can show that chelating agents are pulling out vital nutrients instead of metals and toxins. Then one knows it is time to take a chelation break and let metals re-distribute. Some examples of mineral and vitamin issues found in ZYTO scans are: Needs more Vitamin C, Needs more Vitamin D, needs selenium, needs molybdenum, need to back off on magnesium, etc. Unfortunately, ZYTO no longer allows practitioners and users to scan in their own supplements. I’m not sure how big the database of ZYTO minerals & vitamins is these days. Please fill out the contact form on this site if you have any insight. The section Interpreting ZYTO Scan Results shows how we pull this information out of the scan.
5. Ranking Supplements – This was the most useful part of a ZYTO scan for us. Unfortunately, there is no longer an easy way to scan supplements into ZYTO. Here is my current understanding: Supplements not already in the database must be sent to ZYTO and then ZYTO will scan in the supplements and send them back to you in 30 days. Ugh.
    
   In our case, we had all of our medications, vitamins, minerals, herbs, and homeopathics scanned into ZYTO. Doing this today would be a real pain. Then again, maybe sending a big box of supplements to ZYTO for them to scan in might be worth it. The ZYTO supplement scan can help determine what supplements we need or no longer need. The ‘supplement’ topics that ZYTO is good at include the following:
   • Methylation supplements
   • Drainage remedies
   • Detoxification binders
   • Acute viral & bacterial infection supplements
   • Mineral & Vitamins

   What top 3 drainage remedies do our bodies need? What binder is best for our chelation at this point in time? ZYTO saves me from having to test by hand the 100s of items that I already have in my home. Even though I might find that something is testing well, ZYTO can almost always find something that is even better. This saves me a significant amount of time testing 100s of items by hand on each member of my family. I also save a lot of money because we don’t have to necessarily buy new supplements after every ZYTO appointment. ZYTO will rank what we already have on hand.
    
   Now that it is a lot more difficult to scan supplements into ZYTO, I would recommend asking the practitioner what supplements they have scanned into the database. Ask if they have supplements in the above categories (methylation, drainage, detox, minerals, vitamins, etc). Ask the practitioner if they are willing to work with you and ZYTO to scan in other supplements.

6. Acute Viral & Bacterial Exposures – Acute viral and bacterial exposures that are causing symptoms will often show up as high stressors on a ZYTO scan. This is quite useful, because if they are high stressors, then the balancers will indicate what will work against that virus or bacteria. This is extremely useful if you’re coming down with a cold. ZYTO energetic treatments can sometimes be of use in this case, but I find the suggested Balancers (supplements, herbs, homeopathics, etc) much more useful. This doesn’t mean that ZYTO has found the root cause of why one became sick in the first place.
7. Test New Medications – I also use ZYTO to scan and test new medications (especially prescription meds) before I try them on myself or my children. This is much more difficult now that ZYTO has eliminated the ability to scan in your own supplements. Either scratch this advantage, or find a practitioner who is willing to work with you to send new supplements to ZYTO for entry into the database.

ZYTO Scan: The Bad

ZYTO is not perfect. Specifically I do not rely on ZYTO for the following:
 

1. Chasing Gut Bacteria – Sometimes I feel like ZYTO is chasing bacteria around. If I take a ZYTO-recommended supplement to get rid of some specific bacteria, another bacteria often pops up next time I scan. ZYTO isn’t good at bigger picture items, like fixing leaky gut and recolonizing the gastrointestinal tract. I try to use ZYTO to help with these ‘bigger picture’ items. This includes things like what I need to change in my diet, probiotics that might be helpful, and more broad spectrum supplements that go after the GI bacteria (eg Grapefruit seed extract, Berberine, Caprylic Acid, etc). Healing leaky gut is a long-term process, so I if I have gut issues, I will work on them at home (more details at healing leaky gut). I won’t go back to have a ZYTO scan again until 4-6 weeks at the earliest to see if things are starting to clear up.
2. Chasing Food Allergies Around – When we had leaky gut and dysbiosis in our GI tract, we were coming up on all sorts of food allergies. It seemed like ZYTO was coming up with allergies on the foods that we had recently eaten before the scan. It felt like we were chasing around food allergies, and like we were allergic to everything we ate. Really we needed to focus on fixing the GI problem, but that wasn’t clear from the ZYTO scan. ZYTO can treat food allergies, but they will reappear if the GI issues aren’t fixed. Healing leaky gut is not well understood, so check out that section of this site to make sure all bases are covered.
3. Probiotics – ZYTO might suggest a probiotic to increase the amount of beneficial bacteria. Sounds great so far. The problem is that ZYTO can’t see into the future. This probiotic might also feed dysbiotic bacteria, and ZYTO doesn’t predict that. The probiotic may also feed parasites, and ZYTO won’t predict that either. I am very wary of any probiotic supplements that have FOS or inulin, even if they are testing well on a ZYTO scan. I’ve found that after taking probiotics with FOS or inulin, we often have a nasty flare-up of Lyme and/or gastrointestinal (GI) issues. Our family has learned this one the hard way.
4. Parasites – Parasites are often a root cause of health problems. However, in ZYTO scans, they tend to be buried under all sorts of other viral, yeast, mold & bacterial infections. Sometimes it’s like peeling an onion – if you work on some of these higher stressors then the parasites may show up. Sometimes still not. If parasites don’t show up as high stressors on ZYTO, I would not assume that they are not present. I would also not assume that they aren’t a root cause of the symptoms. The danger is that you might be spending time and money chasing around various bacteria and viruses that ZYTO shows are stressing the system. In actuality, the reason these things are there might be because of a parasitic infection. ZYTO won’t tell you that.
5. Hidden Dental Infections – These also don’t show up on a ZYTO scan. If a child is growing or you just had major cavitation surgery, then teeth will sometimes show up as a stressor. Even then they often do not show up at a very high level. Dental infections are also root causes of many symptoms. The danger is that you might be spending time and money chasing around various bacteria and viruses that ZYTO shows are stressing the system. In actuality, the reason these things are there might be because of a hidden dental infection. Sometimes I can get a clue about dental infections by looking for things like Adrenal problems coming up.
6. Lyme disease – Similar to parasites and dental infections, sometimes Lyme shows up and sometimes it doesn’t. Lyme is especially good at taking out the immune system. This clears the way for other viruses, bacteria and yeast to flare up. These secondary infections are usually the ones that will show up on a ZYTO scan. If Lyme doesn’t show up on ZYTO, I wouldn’t assume that I don’t have it. I have found that if Lyme and co-infections do show up on ZYTO, then they are present. My opinion is that Qest4 (formerly ASYRA) is the gold standard for biocommunication Lyme testing.
7. Antibiotics & Medications – ZYTO can’t see into the future. It may show that a specific antibiotic is testing favorably against the big stressors. However, the antibiotic itself can cause other problems, e.g. gastrointestinal dysbiosis and candida flare-ups. ZYTO can’t see this future effect of the antibiotic until the body is at that point. Only then will the antibiotic no longer test as beneficial.
8. Supplement Dosing – I find dosing more accurate with my home testing than I do the dosing function on ZYTO. A video example we made is called Supplement Testing and Dosing.
9. Laser – I just heard that ZYTO has discontinued their laser. The laser treatments are the ones that were most effective for us, specifically for treating allergies.

ZYTO Scan: The Ugly

We’ve also had a couple of ugly incidents with ZYTO:
 

• ZYTO does not test supplements (balancers) in combinations. The ZYTO Balancer scan is meant to quantify how effective various things are in treating the items that appear as stressors on the scan. These ‘various things’ include supplements, prescription medications, vitamins, chelators, binders, drainage remedies, or whatever else is in the practitioner’s database. These are all tested individually, not in combinations. This becomes especially important when combining prescription medications like parasite medications. Parasite medications might test well individually. However, in combinations they might not test well, because they can overload the liver and kidneys. I typically test combinations of medications of concern by hand. The video Parasite Medication – Which one to take? is an example of testing supplements and medications together.
• Most of the things on the ZYTO scan I don’t understand. I could spend all day Googling for details on the various ZYTO stressors that come up. I can make myself crazy and paranoid very quickly! I finally realized that even ‘normal, healthy’ people have all kinds of scary sounding infections that come up on ZYTO. Are they real? Maybe. Who knows. Our immune systems actually fight off an amazing number of things in the ‘background.’
• Polio came up on my child’s ZYTO scan two months in a row. Talk about scary. Then the polio was mysteriously gone. I’m honestly not sure – maybe the child was exposed to polio somewhere and the body was detoxing it. Lyme is similar to polio – maybe her Lyme was dying off in such a way that it looked like polio to the computer? Don’t know.
• Pneumonia came up high for me once as a stressor, and I had absolutely no symptoms. This was also scary – was I exposed to pneumonia or was I about to come down with it? Who knows.
• A good ZYTO practitioner is essential. Without a good practitioner, things can get ugly rather quickly. ZYTO is capable of closing or overloading detoxification and drainage pathways, just like it is capable of opening them. Our direct experience with this is detailed in the Overview.

I’ve learned to take ZYTO scans with a grain of salt. The technology & software have improved an incredible amount since we started using it six years ago. However, it sometimes still produces inaccurate or seemingly random results. I don’t take the accuracy of the numbers that seriously. If something is testing 10x or 100x better than everything else, then I start paying attention. I’m hoping the technology will continue to improve, and that the scans will become more accurate, useful, and easy to interpret with time.
 
 

How to Find a Good ZYTO Practitioner

I am of the opinion that it’s worth it to go to a ZYTO practitioner. A good ZYTO practitioner has ideas about what might be causing symptoms and can brainstorm stressors to scan and balancers to try. This is not always straightforward. It takes an experienced practitioner to make good ‘guesses’. ZYTO cannot scan for everything in it’s database. This would take too long to scan, and the biocommunication link seems to break down after about 100-200 items. I don’t understand the reason why the body stops communicating well after a few hundred items. However, I’ve heard this from a few practitioners, so I take it at face value.

A good ZYTO practitioner also checks and treats detoxification and drainage pathways. This is extremely important. For example, suppose one is getting a ZYTO energetic treatment for heavy metals. If the practitioner doesn’t check that the liver and kidney pathways are functioning properly, the results can be disastrous!

Another factor is cost. Depending on which code(s) the practitioner bills, ZYTO might be covered by insurance. We have generally gotten our PPO insurance to cover ZYTO. Ask the practitioner to try a few different codes to see which ones might be covered.

Here are my tips for finding a good ZYTO practitioner:

• Make sure they are willing to send new supplements to ZYTO to be scanned into the database. Personally, I wouldn’t work with a practitioner who hasn’t already done this.
• They should be an acupuncturist, or be very familiar with acupuncture, drainage, and detox pathways. Otherwise they can turn you into a monster (see Overview).
• Check with other patients to see if they have had good results.
• I am extremely skeptical of ZYTO practitioners who use ZYTO as a way to sell you supplements. I would work with practitioners who either don’t sell supplements at all, or who do not pressure you to buy supplements.

Interpreting ZYTO Scan Results

What useful information can be obtained from a ZYTO scan, and how do you obtain it? I’m still learning the answers to this question. The best I can do is summarize what I’ve learned in my four years of using ZYTO.

 
Every time I go to ZYTO, I get a scan of my database, which includes drainage remedies, detox items vitamins, medications, and other supplements that we have already on-hand. I usually get a full printout of these items, which ends up being quite a large document. It typically takes me about 45 minutes per person to ‘digest’ the information. It’s kind of like 45 minutes of homework. This includes updating our medication list, supplements list, drainage remedies, and detoxification support. I also consider if any ‘new’ balancers that my practitioner might have scanned make sense to order.

 
Here are some guidelines I use to interpret ZYTO scan results:

• Numbers – The ZYTO scan says all numbers should be taken as absolute values. I find that the negative numbers tend to be more chronic stressors. The positive numbers tend to be more acute stressors. The larger the number, the more stress it is placing on the body at that point in time.
• Stressors – I take any ‘diseases’ or infections found on a ZYTO scan with a grain of salt. I interpret them as detoxing or passing through my body, not necessarily that I have that particular disease. Sometimes the stressors seem to be pretty accurate. Other times they seem inaccurate.
• Drainage – I almost always use the top 2-3 drainage remedies that come up best on ZYTO. This is what I call ‘Disaster Prevention’. I usually apply 5 drops of each drainage remedy on the forearm or skin 2x/day. Sometimes I also take them orally. My experience is that the ZYTO drainage suggestions usually work pretty well.
• Supplement / Medication adjustment – I search the ZYTO document for any supplements that we are currently taking. If they are testing less than -5.0, then I usually scratch them. If they are still testing greater than 5, then I usually keep taking them. If they are between 5 to -5 then I make a judgment call.
• Additional Supplements / Medications – I sometimes add items that are testing the most positive to our regime. I don’t always add the most positive one(s). I add what makes sense to me. If something is testing at a very high number, I always give it consideration.
• Probiotics – I am very wary of any probiotic supplements testing well on ZYTO. ZYTO has difficulty seeing into the future, and FOS or inulin contained in the probiotic are like eating sugar – they can feed good bacteria as well as bad bacteria.
• Antibiotics – I am also wary of antibiotics that test well on a ZYTO scan. While that is interesting information, antibiotics can cause all kinds of other issues, like a candida flare-up or gastrointestinal dysbiosis. ZYTO can’t see into the future to see these other problems that might be caused by the antibiotics.
• Food allergies – If any food allergies come up for us on a ZYTO scan, then I ask the practitioner to look deeper for a bacterial or yeast infection. Avoiding certain foods is helpful, but it isn’t going to help with the root cause of the problem. I then focus on possibilities like tightening up diet, doing the stomach acid test, taking a stool test, and taking supplements for any dysbiotic organisms that appear in the stool test. All these details are in the healing leaky gut section. Another idea is to look for a parasite infection, which could also be the root cause. If things like ‘beef’ or ‘eggs’ show up as a stressor, this could be grain-fed beef or grain-fed eggs. Grassfed beef and grain-free eggs may actually test as beneficial.

Below are some example videos that show how I interpret ZYTO scan results. The first video also has an introduction that summarizes the information in this document.

FAQ

Q: Did you reverse your MTHFR (methylation) mutations with ZYTO?

A: No. We tried and failed. We all still have the genetic mutations. However, we appear to be methylating better with fewer supplements after ZYTO treatments. NOTE: Not all practitioners have methylation treatments. Also, it’s unclear now how well the treatments will work now-a-days without the stand alone laser.

Q: How often do you go to ZYTO?

A: We typically go to our ZYTO practitioner about once / month if we are working on a particular health issue (e.g. parasites, chelation, Lyme), otherwise 3-4 x per year for check-ups. ZYTO scan results can vary on a daily basis. I try to work on the ‘bigger picture’ issues that can be causing the ZYTO stressors. Bigger picture issues like gastrointestinal (GI) dysbiosis, heavy metal toxicity, parasites, hidden dental infections, etc. usually take on the order of months to fix, not weeks.

Q: We are in a very rural area and don’t have access to a well trained ZYTO practitioner. Is ZYTO something we could purchase and use to test products and find issues at home?

A: You can buy a ZYTO machine and do it yourself, but it’s a bit pricey. Pricing aside, I would recommend going to a good practitioner for ZYTO to see the maximum benefits. The machine doesn’t just run by itself. You have to understand the machine and put some thought power behind it.
 

Q: Can Qest4, ASYRA, Bioset, EAV, EDS be done remotely?
A: Not to my knowledge.
 

Q: Do you have any insight, opinions, or experience with the NES system?
A: I have never tried the NES Health system on my family. Why not? First off, I don’t like the fact that they are pushing their own line of products. It makes me wonder if the results of the scan are real or just designed to sell their products. Second, you can’t scan in any of your own supplements. Figuring out which vitamins, minerals, drainage remedies, and detox remedies will work best is one of the main reasons we still do these energetic scans. Again, this makes me wonder if their scans are only designed to sell their products. As for the NES energetic treatments, I have yet to have an independent person tell me that they were helpful. I also know of one practitioner who used NES who has since switched to another technology.
