How it works

From your door to your results

Most tests are collected at home. The Full Immunology Panel needs a blood draw, included at a partner facility in Cedar Park.

  1. Order online

    Choose your test and whether you want interpretation.

  2. Receive your kit

    The kit and instructions are mailed to your address.

  3. Collect at home

    Collect your sample and send it to the lab with the prepaid label.

  4. Get your results

    Results arrive by email. With interpretation, the email includes a link to book your review with Xenia.

Testing information

Ordering a test on its own does not establish a patient-provider relationship. You become a patient after a new-patient visit.

Payment

Insurance doesn't cover these tests, but you can use HSA or FSA funds.

Availability

Not available in New York, New Jersey or Rhode Island, or outside the continental US. The immunology panel is for Texas only.
