The Food Sensitivity Testing Package
Price: $450
Acne, bloating, headaches, fatigue, and inflammation can be tied to foods your body isn’t tolerating well. The tricky part? Reactions are often delayed, which makes it really hard to figure out on your own. This package shows you your top food triggers using real data so you can make changes with confidence.

How do I know if this test is right for me?
If you’ve ever said, “I swear food is breaking me out”… this is for you.
Your skin flares. Your stomach gets puffy. You cut dairy. Then gluten. Then sugar. And you’re still confused.
This gives you a clear list so you can stop guessing and start being strategic.
Minimum required age: 2 years old.
What if I'm taking medications?
Most medications are fine. But a few are important to flag.
Steroids (like prednisone) can suppress immune reactions and may need to be discussed with your doctor before testing.
Immunosuppressants can affect how your body produces antibodies (IgG), which is what this test measures.
Digestive aids like enzymes or stomach acid blockers can impact gut function and are worth reviewing.
Never stop prescription medication without speaking to your doctor first. If you’re currently taking any of these and aren’t sure what to do, email us at support@katiestewartwellness.com and we’ll help you figure out the right timing.
How is this different from regular blood work?
Standard blood work doesn’t test your immune response to 190 foods like this. This looks at delayed reactions that can show up 24–72 hours later… which is why they’re so hard to catch on your own.
How is this different from an allergy test?
Allergy tests look for fast, intense reactions like hives or throat swelling. This looks at slower immune reactions that can show up as acne, bloating, headaches, or fatigue. Different system. Different clues.
I’ve done functional testing before. Why would this be different?
First, this gives you a clear list of 190 foods in one place.
Second, your results are reviewed through an acne lens by a practitioner trained to connect food patterns to skin inflammation.
You’re not just handed numbers. You’re shown exactly what to do with them.
Who does my consult?
Your results are reviewed and interpreted by a qualified practitioner.
One of our KSW nutritionists who's been trained directly by Katie and has been on the team for years. Every single one of our qualified practitioners knows our method inside and out and specializes in acne-focused nutrition.
How does the process work and when do the results come in?
After purchase, you’ll get an email to set up your account in our client portal. Fill out the intake forms. Once everything’s submitted, we’ll send your testing instructions, ship your test kit, and provide your consult booking link (within 24 business hours).
You’ll book your consult for about 4 weeks after you ship your sample. Labs usually take 2 to 3 weeks once they receive it. If timing needs adjusting, we’ll easily move your appointment.
Will I just get my results or an actual plan?
We review your results with you and give you clear, step-by-step instructions on how to use them day-to-day. You’ll also get a simple digestion-focused protocol (supplements + general eating recommendations) to support your gut while you implement.
This does not include a custom meal plan unless you add it on at checkout (see the cart area).
Is this covered by insurance?
We don’t direct bill. You can submit your receipt to your provider, but coverage depends on your plan.
Do I have to live in North America?
No you don't! If you live in NY, NJ, RI, PR or outside of North America, additional shipping fees may apply (please email support@katiestewartwellness.com) to check for shipping rates.
