ICMR has recommended the use of Standard Q COVID-19 Ag detection assay (antigen detection test) as a point of care diagnostic assay for testing under certain settings in combination with RT-PCR test. Those who test negative for COVID-19 by rapid antigen test should be definitely tested sequentially by RT-PCR to rule out infection, whereas a positive test should be considered as a true positive and does not need reconfirmation by RT-PCR test.
