PETALING JAYA: The Antibody Rapid Test Kit (RTK) for Covid-19 or serological tests that use blood samples from a finger prick cannot be used to diagnose the disease, says the Health Ministry.
Health director-general Datuk Dr Noor Hisham Abdullah (pic) said this is because the presence of antibodies are unable to validate active infections while negative results are no guarantee that the individual tested is not infected with the disease.
