Meet Our Founders

Darin & Samantha Upchurch

Darin and Sam Upchurch are the husband-and-wife team behind Advanced Food Intolerance Labs (AFIL) — united by a shared mission: to help people make sense of their wellness.

They created AFIL to bridge the gap between confusion and clarity, offering at-home, non-diagnostic wellness testing that makes it easier to understand possible patterns related to foods, lifestyle, and overall wellbeing. Their approach is designed to help you feel more informed about the choices you make every day — from how you eat to how you care for your body.

We believe: "Your body already knows — we simply help you listen."

Frequently Asked Questions

Find quick answers to your questions and get clarity on everything you need to know about our tests, process, and results.

Our wellness technology is designed to explore possible patterns connected to your everyday relationship with foods — helping you notice connections that may influence how you feel day to day.

It’s completely non-diagnostic and not intended to assess medical conditions. Instead, it offers gentle, educational insights that may support clearer, more confident decisions about your nutrition and overall wellness.*

We use a small hair sample because it’s a simple, non-invasive, and convenient way to take part in our wellness process. Hair grows gradually, which makes it a useful input for exploring possible wellness-related patterns over time — without needles, swabs, or discomfort.

Our digital, non-diagnostic wellness technology uses your sample to highlight general patterns that may relate to foods, nutrients, and overall digestive wellness. And with processing times typically within 72 hours of receiving your sample, you can explore your wellness insights without the wait.*

Don’t worry — color, treatments, or bleach is perfectly acceptable. Take your sample from as close to the root as possible (no follicle needed!)

Just make sure your hair is clean and free of products like gels, sprays, or anything metallic (except for using scissors when taking your sample.)

Shampoo and conditioner are fine to use before collecting your sample.

No hair, no problem! We also accept facial or body hair.

Please provide 10 strands at least 0.5 inches long. If the hair is shorter, provide 20 strands instead.

Hair must be clean and free of products or any metallic residues. You may use scissors to take your hair sample.

If you decide to experiment with adjusting your diet based on your wellness insights, many people try a short trial period — sometimes a few weeks — to notice what feels supportive for them. During that time, you can simply pay attention to how you feel and whether any shifts in your overall wellbeing stand out.*

Always consult your medical professional before making any changes to your diet or health routine.

No.
If you’re trying to understand fast, immune-related reactions — the kind that happen within minutes or hours — an allergy test from a qualified healthcare professional is the appropriate path.

That’s not what we do.
Our wellness technology does not measure immune activity, biochemistry, antibody levels, or anything diagnostic. It cannot detect clinical allergies, clinical deficiencies or otherwise. Instead, it explores possible long-term wellness patterns related to everyday foods, nutrients, and environmental items that some people find helpful for reflecting on their overall wellbeing over time.*

The fine print:
This is a general wellness tool, not a medical test or clinical diagnosis. It is not designed to detect, treat, cure, or prevent any disease. Always consult a qualified healthcare provider for any medical concerns — especially anything related to allergies.*

Absolutely — this non-invasive wellness tool can be used for all ages. For children under 6, wellness patterns may naturally change more frequently as they grow, so some parents choose to explore possible wellness patterns periodically to support their understanding over time.*

Note: This is a general wellness tool, not a clinical or allergy test. Please ensure you consult a qualified healthcare provider or paediatrician for any medical concerns, including allergies or health conditions.*
