  • Know your levels: Measure antibodies from vaccination or natural infection
  • Test the right thing: Measure S protein antibodies, which most vaccines are designed to stimulate your body to produce
  • Test conveniently and painlessly: Painless blood collection with the TAP device
  • Be confident: Best-in-class, certified laboratory results
  • Online results: Results available on the YourBio Health portal just 1-2 days after the lab receives your results
  • Clear reports: Easy-to-understand reporting that shows whether your blood sample was positive or negative for S protein antibodies to the virus that causes COVID-19
  • Be vigilant: Purchase additional kits to monitor your antibody levels over time
  • Satisfaction guaranteed: If you are unsatisfied for any reason, in addition to your legal rights, you may request a refund within 90 days


  • Results from this test should NOT be used to diagnose a current COVID-19 infection or to inform about the status of an infection
  • Conclusions about protective immunity to future infection cannot be made on the basis of the results provided
  • If an acute COVID-19 infection or recent exposure is suspected, direct testing with a molecular or antigen based SARS-CoV-2 test (not this test) is necessary
