3 Crucial Health Lessons From My GPL-TOX Test

As a clinician, I have also used the data from lab tests to guide my decision making. Both for my personal life, and for my clients. It’s just how I was trained, in the same way a disciplined private detective goes through each meticulous step when investigating a murder—sorry, I’ve been on a huge murder mystery kick lately. 

Whenever I can, I choose to base my protocols from various tests instead of opinion. It’s a mindset that has served me well throughout my career, and it’s one that led me to dive into the world of nutrigenomics

Since testing applies to my personal nutrition journey as well as that of my clients, I use Great Plains Lab. They’re the best company in the world when it comes to diagnosing metabolic, mitochondrial, and environmental factors as they relate to chronic illnesses. 

They offer a wide variety of tests, and provide in-depth details for various markers. 

The most recent test I did on myself is the GPL-TOX test, which tests your body for its non-metal toxin profile across 19 different markers. 

And, if I can be honest with you, my test results were quite shocking because I had WAY more toxic markers than I would’ve thought. Which, as you’ll see, proves that your diet alone isn’t enough to achieve optimal health. 

As a practicing nutritionist, I eat healthy. I don’t eat a “perfect” diet (I’m not even sure if that’s possible). But I eat much healthier than the average person, and that also extends out to the average wellness-focused person. 

How do I know this? 

Well, I limit my carbs and almost never eat sugar or refined carbs or processed foods. I eat organic food whenever possible. My house is filled with different supplements and nutrition drinks to support my health. I enjoy cooking, and cook the majority of my meals at home. And, as previously alluded to, I take various tests most people have never even heard of to gauge my metabolic health. 

Enter the GPL-TOX test where I discovered I had more toxic markers than I would’ve thought, considering my lifetime dedication to nutrition and healthy living. 

Let’s look at some of my results from my GPL-TOX test, so you can see this for yourself: 

Analyzing My GPL-TOX Results 

The GPL-TOX test looks at 19 different markets. 9 of the 19 markers were “green,” meaning I have a low level of toxins. 6 of the 19 were “yellow-orange,” meaning moderate levels of toxins. And 3 of the 19 were “red,” meaning I had high levels of toxins. (If you’re adding up the numbers, you might realize that only adds up to 18… there was no data for one marker.) 

I’m going to show you a few markers from the moderate or high level of toxins groupings. Then, I’ll explain what these markers mean, why they might’ve happened, and what I can do to get rid of them. 

According to Great Plains, the first three markers I’m showing you (marker #1, #4, and #8) are common. But the last one (marker #15) is not common. 

If you’re looking for a more in-depth scientific dive into the common toxin markers—like the first three in this article—I recommend checking out this article: GPL-TOX: Health Concerns and Exposure of Common Markers

But for a more personalized analysis, keep reading: 

1. Marker #1 — 2-Hydroxyisobutyric Acid (2HIB)

This marker comes from two types of gasoline additive (MTBE and ETBE), which are used as octane enhancers to replace lead. Of course, they’re also toxic. 

And while we’ve been phasing these out since the early 2000’s, they still lurk in the soil, potentially contaminating water supplies. 

Having this marker can lead to acute problems like nausea, headaches, dizziness, ocular irritation, and confusion. As well as chronic symptoms like central and peripheral neurologic change, liver and kidney damage, leaks from the gallbladder into other areas of the body, unshakeable sleepiness, and low white blood cell count. Plus, in animals, it has been shown to be carcinogenic. 

Great Plains recommends sauna use, niacin supplication, glutathione (reduced) supplementation, and even ketogenesis as possible solutions. And it makes me wonder if following a ketogenic protocol means I have fewer toxins than I otherwise would have for this marker. 

2. Marker #4 — Phenylglyoxylic Acid (PGO)

This next marker, Marker #4, tests for styrene — a man made chemical found in car exhaust fumes, cigarette smoke, and in plastics, rubbers, and resins. 

Plastic food containers and styrofoam cups cause the most styrene exposure, which is why this is a common toxin many people have. Heating these containers is especially dangerous for toxin levels, so I would avoid putting them in direct sunlight or your microwave if you don’t have glass tupperware. 

While this toxin can cause acute symptoms, it generally only happens during extended styrene exposure, which would only happen if you work with styrene. The more common problems caused by styrene happen because of chronic ongoing exposure. 

If you’re feeling fatigued, weak, depressed, notice CNS dysfunction (such as reaction time, memory, visuomotor speed and accuracy, intellectual function), have difficulty hearing, or peripheral neuropathy, you might have had a chronic exposure to styrene. 

Switching from plastic containers to glass, paper, or stainless steel containers is an easy way to reduce your exposure. Great Plains also recommends sauna treatment and reduced glutathione supplementation.

3. Marker #8 — Diphenyl phosphate (DPP)

Marker #8 was by far my worst result. While it’s common, it’s not ideal. 

This marker tests for organophosphate flame retardant triphenyl phosphate, or TPHP, which is used in plastics, electronics, nail polish and resins. This toxin usually affects women and children more, but can also be found in your water supply. 

TPHP causes a bunch of health risks such as:

  • Endocrine disruption, 
  • Reproductive and developmental problems
  • And it’s potentially carcinogenic

Great Plains doesn’t offer much about reducing the toxins besides avoiding common exposure sources. But since saunas are a fantastic way to rid your body of toxins, I’d recommend jumping in one for 10-20 minutes a day. 

4. Marker #15 — Diethylphosphate (DEP)

This is the only marker I showed toxic levels for that isn’t common. This marker tests for one of the most toxic substances in the world—organophosphates—which are found in pesticides, particularly insecticide. 

Since I live in a suburban neighborhood filled with freshly sprayed lawns and lavish golf courses, two prime suspects for using insecticides (which can be inhaled from the ground), this one concerned me quite a bit. 

They inhibit certain cholinesterase enzymes, which can overstimulate your nerve cells, and result in excess sweating and salivation, diarrhea, aggression, depression, vomiting, tremors, muscle paralysis, and even death! 


Being exposed as a child doubles your risk of developing autism. Being exposed while pregnant can cause shorter pregnancies and children with impaired reflexes. 

And, unfortunately, in the U.S. we go through 749 million pounds of pesticides! 

Great Plains recommended eating organic foods, avoiding the use of pesticides in your house and garden, and staying indoors—with your windows shut—if someone’s spraying insecticides nearby. They also recommend avoiding lice shampoo, pet flea collars, and flea spray as these are other major sources of organophosphate exposure. 

3 Lessons From My GPL-TOX Test To Apply To Your Life

I didn’t write this article to scare you. But instead, to give you a better picture of how complicated your health and wellness can be. 

With that said, there are 3 lessons you can take from this and apply into your own wellness regimen:

Lesson #1: Health and wellness extends far past eating a healthy diet. 

Toxins surround us. We cannot escape them. Every time we eat, drink, or breathe we may let toxins in. 

But simply knowing how omnipresent they are will help you make smarter, healthier decisions. (Like taking your own GPL-TOX test for example.) 

Here’s the cold, hard truth: 

You’re going to come into contact with toxins no matter what you do. Instead of trying to avoid them, you should try to minimize the impact they make. Adding a 10-20 minute sauna session to your daily routine, for example, goes a long way for eliminating toxins.  

Lesson #2: You cannot be perfectly healthy when toxins are present. 

The bad news? 

You can’t avoid this. 

The good news? 

Your body can handle a good amount of toxins before they sabotage your quality of life. And your body can handle even more toxins when you optimize the controllable aspects of your health such as:

  • Your lifestyle
  • Diet
  • Exercise regimen
  • Sleep Hygiene 

In fact, these controllable habits can be the difference between feeling great and feeling meh.

Lesson #3: You need lab tests to determine your overall health and wellness. 

Remember how I said I like to use data from lab tests to base my decisions on instead of my opinions? This GPL-TOX test proves why. 

All the biohacks, fasts, meditations, exercise, etc. you do doesn’t mean that toxins aren’t lurking in your body, gradually derailing your health. 

The body is a complex machine — and it’s impossible to know exactly what’s causing ill-health without tests. 

Ready To Get Tested? 

After reading this article, I bet you’re wondering how you can take a GPL-TOX test too. 

Well, here’s some more good news: 

I’m a practitioner with Great Plains Lab, so I can help you get a test. 

Even better news? 

The GPL-TOX test is a urine test, meaning you don’t need to stick needles in your body or go through a more “personal” testing process. 

The GPL-TOX test only costs $229, which is a small price for clarity into your overall health and wellness. 

If you’d like to order a GPL-TOX test through me, you must have an account on my practice portal: www.GetHealthie.com – let me know you are interested in this test and I’ll have one sent to you in the mail. 

If you don’t already have an account on my portal , you can set one up here.

If you do have a GetHealthie account already, simply reach out to me there and I’ll order one for you. Then, you can administer the test yourself (it’s a simple urine collection), mail it back to Great Plains, and I’ll help you interpret your results.
