The Genrui brand of Covid-19 antigen tests is being pulled from the shelves of retailers following advice from the Health Products Regularity Authority.
The brand was under investigation after there were numerous reports of the tests producing false positive results.
A GP said '100s' of people got in touch with her about false positive results when using the Genrui brand.
A spokesperson for the regulator said in a statement: "The Health Products Regulatory Authority (HPRA) today 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."
They added: "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, are advised to still follow the current public heath advice on the HSE website.
Cork GP Dr Niamh Ni Loinsigh posted on social media that hundreds of people had contacted her about false positive test results with the Genrui brand.
She wrote on Twitter: "Received 100s of messages through my Insta about Genrui antigen tests. When pcr was available there seemed to have been lots of false positives with these kits. This could have major implications for people now with no pcr available."
