Recent study by Wang et al (6) using 1070 clinical specimens such as bronchoalveolar lavage fluid (BLF), fibrobronchoscope brush biopsy (FBB), sputum, nasal and pharyngeal swabs, urine, feces and blood collected from 205 patients revealed a dynamic profile with high detection rate of virus from lower respiratory tract (LRT) specimens, i.e., BLF and zero detection from urogenital tract specimen, i.e., urine. Therefore, the aim of this systematic review was to establish the profile of detecting SARS-CoV-2 from different types clinical specimens using a standard diagnostic test (qRT-PCR). A systematic review protocol was developed based on the question "What is the positivity rate for SARS-CoV-2 using qRT-PCR in different types of clinical specimens".	./cache/cord-343128-sh77c0af.txt	./txt/cord-343128-sh77c0af.txt
