The Extend Toxin Test
Just pee once and discover the terrifying truth inside your body No fasting No waiting Just a single morning urine sample and you’ll know exactly what’s poisoning you
by Dr. Darshan Shah
You will discover how I...
...use advanced toxin testing to uncover hidden environmental, chemical, and heavy metal exposures often long before symptoms show up
...help patients eliminate brain fog, fatigue, and chronic inflammation by identifying the toxic root causes standard labs miss
...create targeted detox, nutrition, and lifestyle protocols based on real toxin data not trends, guesswork, or generic advice
P.S. This is not your typical “detox kit.” Trusted by high performers, wellness pros, and physicians, the Extend Tox Burden Test gives you the clarity to cleanse smarter, feel better, and protect your long term health.
Meet Dr. Darshan Shah, the Doctor Trusted by Celebrities, CEOs, and Health Optimizers Worldwide
This isn’t some random online test, it’s built by a physician at the top of his game.
I'm Dr. Darshan Shah, founder of NextHealth, a longevity and performance medicine clinic trusted by world class athletes, CEOs, and health optimized individuals around the world.
For over two decades, I’ve helped thousands of patients who seemed perfectly healthy on the surface but were silently carrying toxic burdens that sabotaged their energy, focus, and long term vitality.
That’s why I created the Extend Toxin Test to help you uncover what’s truly disrupting your health from the inside out before it turns into chronic illness or burnout.
“Symptoms are the smoke. Toxins are the fire.”
— Dr. Darshan Shah

Feeling Off, But Told You’re Fine?
What This Test Can Reveal That Others Don’t:
• Think your yearly labs mean you’re in the clear? Most traditional tests completely overlook the toxins quietly building up and disrupting your body’s balance
• Three types of toxic overload nearly everyone is carrying right now, including heavy metals, mold byproducts, and environmental chemicals that can sabotage your brain, gut, and hormones
• Still guessing with cleanses and detox teas? Without real toxin data, you are spinning your wheels and missing what your body actually needs to eliminate
• Most people have no idea how toxic their environment has become. This test shows you exactly what your body is storing and how it is impacting your health
• The same toxin markers used by functional medicine doctors and high performance health programs are now available through a simple at home test with physician level insights
• That nagging fatigue, brain fog, or bloating might not be about stress or aging. It could be your body fighting a silent toxic burden you have never been tested for
• Struggling with skin issues, hormone swings, or mood dips? Toxin exposure could be the hidden trigger and this test brings it into focus
• If your energy crashes in the afternoon or your sleep never feels restorative, the problem might be toxic interference with your mitochondria or nervous system
• Your detox pathways may be blocked without you even knowing it. This test helps identify how well your body is processing and clearing what it is exposed to
• Forget confusing detox trends. This is precision testing paired with a clear action plan personalized to your toxin profile

Common Questions
How long does it take to get my results?
Once your sample reaches the lab, your results are typically available in about 1-2 weeks. You’ll get a notification as soon as your report is ready in your secure online portal.
Will I be able to understand the results on my own?
Yes, but you won’t be alone. You’ll receive a beautifully designed results dashboard, an easy-to-follow interpretation guide, and a 1-on-1 consultation with a trained health specialist to walk you through every key biomarker and what it means for your health.
Is the test covered by insurance?
This test is not covered by insurance, but it’s designed to provide a level of insight most insurance-covered tests don’t offer. It’s an investment in personalized, preventative care — not a generic, reactive approach.
Do I get a 1-on-1 consultation?
Yes. Every test includes a private, one-on-one video consultation with one of our trained health experts. They’ll walk you through your results and help you create a plan tailored to your goals.
Is this available across the U.S.?
We currently ship to 49 states in the U.S. Due to local lab regulations, we’re not able to ship to New York at this time. However, all other states are fully supported with fast and secure shipping.
Do you offer international shipping?
We currently ship to the U.S. and Canada only. We’re working on expanding internationally very soon — if you're outside North America, stay tuned.
Is this test just for people with health problems?
Not at all. In fact, some of our biggest success stories are from people who were already considered healthy — but wanted to take control of their future. This test helps you identify silent imbalances before symptoms appear and optimize everything from energy and focus to aging and recovery.
Do I need to take this test more than once?
We recommend retesting every 3–6 months. Your body is dynamic, and regular testing allows you to track progress, catch issues early, and make real-time adjustments to your nutrition, supplements, and lifestyle.
Can I use these results to guide my supplement and lifestyle plan?
Absolutely. This is exactly what the test is built for. You’ll not only receive data-backed recommendations, but your personal health consultant will help you design a plan that’s tailored to your biology — no more guessing.
What happens after I get my results?
Your results will be uploaded to your secure online portal with visual graphs, explanations, and key takeaways. Then, you’ll meet with one of our certified consultants who will walk you through every detail, answer your questions, and help you decide exactly what to do next.
