Who is eligible to purchase and take a Picnic Home Allergy Test?

The Picnic Home Allergy Test can be purchased and used by adults 18 years or older in all US states except for Delaware, Idaho, New Hampshire, New Mexico, New York, West Virginia, and Washington, DC. This is due to state laws around the use of telemedicine or at-home allergy testing specifically.

Can the Picnic Home Allergy Test clinically diagnose my allergies?

Yes! Doctors can make a specific allergy diagnosis using either a skin prick test or a specific Immunoglobulin E (IgE) test like the Picnic Home Allergy Test. Once your lab results are available, your Picnic doctor will interpret them in the context of your clinical history to provide you with a diagnosis.

However, this only applies to environmental allergens like pollens, pets, dust mites, and mold. Other kinds of allergies like food, latex, and insect stings require a higher level of interpretation with an in-person allergist before you can receive a diagnosis. While you’ll see specific IgE levels for these allergens in your test report, these results describe sensitization only.

What’s the difference between sensitization, allergy, and intolerance?

This test measures IgE, an antibody your body makes to defend itself against allergens. If IgE is present in your blood for any given allergen, you’re considered to be sensitized to it.

You’re only allergic to something if you’re sensitized to it and you have a history of symptoms around it. If you’ve never had a history of allergic reactions to a particular trigger, any results that seem positive based on your IgE levels could be false positives.

Food intolerances are something different. While allergies affect the immune system, intolerances affect the digestive system. And in fact, there’s no evidence that the presence of the antibodies that at-home food intolerance tests measure can reliably predict intolerances anyway.

What’s the difference between Immunoglobulin E (IgE) and Immunoglobulin G (IgG)? Which one does the Picnic Home Allergy Test test for?

When you have a genetic or environmental predisposition to developing allergies, your body’s T-cells and B-cells interact to produce an antibody called IgE in response to a specific allergen.

IgG is another antibody your body produces after encountering certain foods. However, the presence of specific IgG in your blood only indicates past exposure to that food and not necessarily an intolerance.

The Picnic Home Allergy Test only measures IgE as IgG is not involved in allergic reactions.

How reliable are the results compared to other at-home allergy tests?

The results of the Picnic Home Allergy Test are comparable to those of ThermoFisher’s ImmunoCAP, considered the gold standard in allergy testing in terms of specificity and sensitivity, but with a significantly reduced risk of false positives—due to our unique CCD-blocking technology—relative to other at-home allergy tests that don't utilize this technology.

What testing technology does the Picnic Home Allergy Test use?

We use the ALEX2 technology developed by our global partner MacroArrayDx. This is a multiplex IgE test that uses a solid-phase immunoassay to test for 294 allergens (which cause 99% of all allergies). This proprietary technology also significantly reduces the risk of false positives due to the presence of cross-reactive carbohydrate determinants (CDS).

How does Picnic’s Home Allergy Test compare to other at-home allergy testing products?

The Picnic Home Allergy Test tests for 294 potential allergens, which is 85% more than most other at-home allergy tests. Our partner lab is CLIA-certified as well as CAP- and COLA-accredited, ensuring that they adhere to the most comprehensive and scientifically endorsed laboratory standards.

Plus, because we consider your clinical history of symptoms as well as your blood test results, we’re able to provide true allergy diagnoses rather than just a report of IgE sensitization.

What happens after I order my Home Allergy Test?

After you complete your purchase, we’ll direct you to answer a few questions about your allergy symptoms so your doctor can provide you with a real allergy diagnosis. We’ll also ship you your test kit. Once it arrives, follow the step-by-step instructions provided in the box to collect your blood sample and activate your test online.

Then, you’ll pack your sample in the prepaid return envelope provided and mail it to our lab for testing (within 24 hours of taking it). When your results are available, we’ll share them with you as well as your doctor to assess and put together a diagnosis. If you have any questions after receiving your results, you can message your doctor directly.

How much blood do I need to provide?

600 microliters (that’s about ⅛ of a teaspoon). Any less and we can’t guarantee we’ll be able to test your sample. All you need to do is fill the sample tube to the 600 line and you’ll be set.

Please note that you’ll also need to write your date of birth on your sample tube so the lab can verify it’s yours.

How long will it take to receive my results?

About a week after you mail us your blood sample, you’ll receive your test results as well as a note from your doctor containing your specific allergy diagnosis. We’ll send you an email when they’re ready.

What does the Picnic Home Allergy Test kit include?

The kit includes everything you’ll need for your allergy test: an instruction booklet, a sample tube, three sterile lancets, alcohol wipes, bandages, a welcome card with your unique activation code, and a prepaid return label and envelope.

Is the Picnic Home Allergy Test FSA/HSA-eligible?

Yes, most FSA and HSA cards are accepted by Picnic. If yours isn’t accepted during the checkout process, simply shoot us an email at help@picnicallergy.com asking that we add your card to the list of accepted cards, and we’ll work with our payment processor to get your payment approved.
