Background: As covid-19 is declared as public health emergency since January-2020 Medical Professionals and researches were eagar to test the lethal virus. One test was Real time polymerase chain reaction (RT-PCR) and another was Antibody tests have emerged as vital technique to prove positivity of the virus. Method: 92 patients having clinical symptoms of covid-19 and 92 controlled have studied. Throat swab is collected by using a foam swab with transport medium for detection by RT-PCR detection. Blood sample (5 ml) was collected from each patient for antibody test. Results: RT PCR was 75% positive sensitivity was 81.5 % and specificity was 100%. Antibody positivity was 80%, sensitivity was 86.9%, and specificity was 84.7%. In combined (Antibody + RT-PCR) test 96.7% positive 96.7% was sensitivity, 93.4% was specificity. Conclusion: RT-PCR test gives an idea if people within the immediate proximity of newly confirmed patients are infected by the virus. However first negative result does not completely lack of infection. Therefore (two) 2 weeks quarantine isolation is essential. In such scenario antibody test data gives an important insight on spread of the virus. Hence both tests are equally important to confirm the diagnosis of covid-19.
