About this test
IgG food reactivity measures antibodies your immune system has made to specific foods, from a few drops of blood. The report ranks each food by class, from little or no reactivity to high.
Reactivity is information, not a verdict: IgG shows exposure and immune response, not a food allergy, and it does not diagnose a condition. The ranked list is a place to start a conversation with a clinician or dietitian about what to look at first.
What’s in the box
- Collection card
- Circles to fill with a few drops of blood. Let it dry before you pack it.

- Prepaid return mailer
- Addressed to the lab. Drop it in any USPS mailbox, ideally the same day.
- Instructions and kit ID
- Register the ID online before you collect, so your results reach your account.
Reading your result
Your report shows your IgG food reactivity next to the lab’s reference range, with plain-language context for what a higher or lower value can mean. A single value is a snapshot: it is read alongside how you feel, and a repeat shows whether it moved.
