Critical Questions when Interpreting Coronavirus PCR Diagnostics	2020-06-14		.txt	text/plain	1912	121	57	In contrast to other PCR examinations, or laboratory medical analyses, currently SARS-CoV-2 diagnostic information about the device or the detection limit / sensitivity is not usually provided by the laboratory. Using a protocol without purification of viral RNA, i.e. the Munich Extraction Protocol (MEP) [2] , we could show that the type of transport medium had little influence on the detection sensitivity of SARS-CoV-2 in the PCR (Table 1) . By using this system, the sensitivity could be increased by at least one more dilution step compared to the use of commercial purification methods in PCR (Table 3) . . https://doi.org/10.1101/2020.06.11.20127241 doi: medRxiv preprint Table 1 Comparison of different types of transport media for their influence on the detectability of SARS-CoV-2. . https://doi.org/10.1101/2020.06.11.20127241 doi: medRxiv preprint Table 2 Comparison of different purification systems for their influence on the detectability of SARS-CoV-2 (Cp = crossing point).	./cache/cord-291281-ygrh8ces.txt	./txt/cord-291281-ygrh8ces.txt
