Post Positive PCR Antibody Testing Initiative (PPPATI)

A UK-wide national antibody programme is being launched across England, to support the UK Government and NHS to better understand vaccine effectiveness and immune response to COVID-19.

The new antibody testing service will be known as the Post Positive PCR Antibody Testing Initiative (PPPATI).

PPPATI will offer everybody over the age of 18 the opportunity to opt-in to antibody testing when registering for a PCR test via GOV.UK. Randomly selected individuals, out of those who opt in and subsequently test positive for COVID-19 following a PCR test, will be sent two finger prick antibody tests to complete at home and send to labs for analysis.

The first antibody test will be taken immediately after testing positive, and the second test will be taken 28 days after testing positive.

Individuals will receive their antibody test results directly and the results will be linked to GP records.
