How do I prepare for the blood draw for covid long haulers?

  • Fasting or other special requirements are not required for testing.
  • It is important the blood specimen arrives at the lab within 48 hours of collection to get valid results. The specimen may be rejected, and you may be asked to redraw if it’s older than 48 hours at your own cost. Any repeat testing is not covered in this fee. So, please schedule your draw and ship only Monday through Thursday and use the Priority overnight FedEx label provided for delivery the next morning.
  • Please do not freeze the blood, it will clot the specimen and will be rejected. You can refrigerate temporarily if needed to.
  • When the testing is complete, we will provide your test report and a receipt to claim from your insurance. Please note that, due to restrictions in some states, your insurance may not reimburse the test fee, and Radiance is not responsible for the insurance reimbursement.
  • Please check your spam folder for results and delivery confirmation. If you don’t receive results within two weeks, please contact us immediately.
