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 process, and digita

We use a small hair sample in AFIL’s proprietary bioenergetic wellness assessment. Our system records response patterns from your sample and compares them with AFIL’s reference library to create a personalized wellness profile covering foods, nutrients, and digestive wellness.

This assessment is for general wellness exploration. It does not diagnose allergies or medical conditions.

After your sample is received and logged, processing typically takes 1–3 business days.

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.

Our digital, 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.

Colored or bleached hair is accepted only if you have untreated regrowth near the scalp. Collect 10–20 strands by gently plucking them or cutting them as close to the scalp as possible. Include the 1 inch nearest the root so the sample contains untreated regrowth.

Make sure your hair is clean and completely dry. Avoid heavy styling products or additional treatments.

No scalp hair? Facial or body hair can be used.

Collect all strands from one localized area. Provide at least 10-20 strands that are each 0.5 inches or longer.

You can gently pluck the strands or cut them as close to the skin as possible. Make sure the hair is clean, completely dry, and free of products or metallic residue.

AFIL does not prescribe dietary changes or a specific timeframe. If you choose to adjust your diet, some people prefer to try a short period, such as a few weeks, while noting their personal experience.

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

No. AFIL is not an allergy test and does not diagnose clinical allergies or measure allergen-specific antibodies or immune responses. If you suspect an allergy, consult a qualified healthcare professional, who can evaluate your history and determine whether clinical testing is appropriate.

AFIL uses a hair sample in a general wellness assessment. It compares response patterns from the sample with proprietary reference patterns associated with selected foods, nutrients, and environmental items. The report does not identify allergens.

AFIL is not intended to diagnose, treat, cure, or prevent any disease or medical condition.

Children may participate with a parent or legal guardian’s consent and help with sample collection. AFIL is a general wellness assessment, not a pediatric medical or allergy test, and it is not intended to diagnose or monitor a health condition.

For a child’s health or allergy concerns, consult their pediatrician.
