From the diagnostic perspective, Reverse transcriptase polymerase chain reaction remains the gold standard. However, issues associated with gene primer variation in different countries, low analytical sensitivity, cross-reactivity with certain human coronaviruses have raised serious concerned within the scientific community. Alongside longer turnaround times, requirements of sophisticated equipment and trained technicians are the other challenges for conventional reverse transcriptase polymerase chain reaction testing. The recent biotechnological boom has now allowed newer nucleic acid testing options for diagnosing severe acute respiratory syndrome coronovairus 2 with much better diagnostic efficiency, reduced turnaround times and possible benefit for use as a point-of-care test. ---Continue Author Biographies Sabeen Khursheed Zaidi, Department of Pathology, Karachi Institute of Medical Sciences, Karachi, Pakistan Assistant Professor of Pathology & Clinical Virologist Mehreen Gilani, Department of Pathology, PNS Hafeez Hospital, Islamabad, Pakistan Consultant Microbiologist Downloads Full Text Article Published 2022-02-12 How to Cite Sikandar Hayat Khan, Zaidi, S.
