At Polygenyn Ltd. we are now carrying out COVID-19 antibody tests at our laboratory in Newport. These tests have been CE marked and manufactured under ISO 13485 certified management system.

The COVID-19 antibody tests are used for determining whether a person has been exposed to the COVID-19 virus or how effective a vaccination has been. The tests have an overall specificity to the COVID-19 virus of 97% and a sensitivity of 95%. These tests are useful between 10 and 21 days after exposure to the virus.   These tests will show whether you have antibodies to the COVID-19 virus. Currently exposure to the virus has been shown to give at least 83% protection. The antibody tests can be used for people who have had no symptoms of COVID-19 but are interested to see if they have been exposed to the virus.

A simple small blood sample is taken by fingerprick from a qualified sampler. The results are available within 15 minutes of sampling using a lateral flow test cassette. Results can be used to determine whether you have been exposed to the virus. Retesting maybe needed to determine how long the antibodies are present in the blood. We have detected active antibodies in individuals 6 months after intial exposure. The results may also be used to determine the effectiveness of the COVID-19 vaccine. We have results to suggest  that long term antibodies are already detectable only 3 weeks following vaccination. Regardless of your antibody test result, you must continue to follow current government guidelines around social distancing and self-isolation.
