Target population included all patients who developed COVID-19 related symptoms and/or also had history of recent travel or closed contact with Covid-19 patients. Total 1500 nasopharyngeal PCR tests were done by a team of trained technicians. Systemetic probability sampling technique was utilized. Subjects were divided into two groups by using even and odd serial numbers. Proportion of positive test results were compared between two groups by using chi square test.</p><p><strong>Results:</strong> Results were collected for 3000 nasopharyngeal swab sample for RT-PCR testing. Mean age was 31.68 ± 11.89 years. In study group with modified technique, 470 tests were found positive for a total of 1500 samples while only 297 out of 1500 samples were detected positive in control group with standard technique. Chi square test applied to assess the difference between this proportion and it proved that the difference was highly statistically significant (p-value &lt;0.00).</p><p><strong>Conclusion:</strong> we interpret that modified samples collection technique is relatively safe for sample collector of Covid-19 PCR which has got potential benefits to get more genuine results of these......</p> ER -
