We have a large number of patients who test positive through CT, but are not reported,\u201d he said.<\/p>\n<p>Dr Hassan said RT-PCR, which uses swab for the detection of Covid-19 infection has a sensitivity of 60%-70%. That means more than 30% of positive cases may be missed by the test.<\/p>\n<p>\u201cAnother swab test which is now widely used is rapid antigen test. It has a sensitivity of around 50 percent, which raises the possibility of missing more than half of the positive cases,\u201d he said.<\/p>\n<p>\u201cLow sensitivity of swab tests implies that many patients with Covid-19 infection may not be identified and consequently are not isolated from healthy population. And these individuals will continue to spread the disease in the community,\u201d he added.<\/p>\n<p>\u201cStudies have shown that CT has a greater sensitivity ranging from 86% and 98% for detecting positive cases, while having a lower false negative rate than the lab tests,\u201d Dr Nisar said<\/p>\n<p>\u201cIn a study of 1,014 patients published in the Journal Radiology, researchers in china found that 88% of the patients showed chest CT findings indicative of Covid-19, while RT-PCR test detected only 59 percent of cases.
