Retailers advised to remove Genrui antigen tests following false results

The Health Products Regulatory Authority (HPRA) tonight states that based on its advice, retailers are removing the Genrui SARS-CoV-2 Rapid Antigen Self-Test from sale on a voluntary basis pending further investigation.

This follows receipt by the HPRA of over 550 reports in recent days from Irish consumers of false positive results associated with the use of this particular antigen self-test.

Rapid antigen tests, like all diagnostic tests, have the potential to provide false negative or false positive results. However, the HPRA states that the rapid rise in the number of reports of false positive results relating to the Genrui self-test is significant and a precautionary removal from sale is warranted while the matter is further investigated by the manufacturer (Genrui Biotech, Shenzen, China) and its European representative. The HPRA also advises against the online purchase of Genrui self-tests at this time while the matter remains under investigation.

Individuals who have received a positive result following use of any rapid antigen self-test, including this test, should follow the current public heath advice on the HSE website.

The HPRA will continue to liaise with the manufacturer to investigate the matter further, and is also in contact with other European Competent Authorities in relation to this issue.

Individuals who have experienced a false positive or false negative result can report the occurrence via the HPRA website –

The HPRA acknowledged the cooperation and swift response of retailers in relation to this matter. Any retailers supplying this product who have not yet received communication in respect of this issue should contact
