KLANG: Shah Alam MP Khalid Samad can now heave a sigh of relief after testing negative for Covid-19 following a polymerase chain reaction (PCR) test. In a rapid antigen test (RTK-Ag) on Wednesday (Aug 11), he tested positive for Covid-19. “I first did the RTK test and it showed positive, but I felt fine and did not have any indication of being infected. Given that the PCR test is deemed more conclusive than the RTK test, Khalid said he would regard himself as negative for Covid-19. Khalid, who is also Amanah’s communications director, had been under self-quarantine from early this month after his first aide tested positive.
