Data from 2 major civic labs in Mumbai shows that as much as 65%of symptomatic clients who had evaluated negative for Covid in antigen tests were later on validated positive in RT-PCR testing. While this underscores the danger of false negatives in fast antigen screening, Delhi has actually reported a substantially greater success rate than Maharashtra using the exact same method.
