2. Prescription

Once your doctor prescribes the test, Adaptive will ship you a T-Detect COVID Test collection kit and our mobile phlebotomy (blood draw) partner will call you within two business days to schedule a blood draw.

3. Blood draw

A mobile phlebotomist (blood draw technician) will draw your blood and ship the kit to Adaptive for processing.

4. Results

Adaptive will send your doctor results to share with you.

Samples are processed in 5-7 days of receipt in the lab. Estimated total time for results is 7-10 days from the time of blood draw.

Why T cells?

  • T cells are the first responders of the adaptive immune system.
  • T cell responses persist in the blood long after antibody responses wane.1
  • High specificity: T cells can detect 70% of the parts of the virus, while antibodies can only detect 30%.2
