cord-309986-p7pqla6l	Harkin, Timothy J	Delayed diagnosis of COVID-19 in a 34-year-old man with atypical presentation	2020-05-18		.txt	text/plain	2110	118	52	[1] [2] [3] Infection with SARS-CoV-2 is confirmed by real-time RT-PCR, typically done on naso pharyngeal (NP) swabs or, less commonly, samples from the lower respiratory tract, including broncho alveolar lavage (BAL). 5 Here, we present a man who developed rapidly progressive pulmonary disease and, following two negative NP tests, was diagnosed with COVID-19 on the basis of broncho scopic biopsy and BAL after 9 days of illness. Both the finding of acute lung injury in the area of lung affected at the onset of symptoms, and the positive RT-PCR test for SARS-CoV-2 in the BAL, support the diagnosis of COVID-19 to explain the entire hospital course. normal in the first 48 h (appendix p 1), serum and BAL galactomannan were negative, and the pathological finding of acute lung injury in the lesion was already present on day 2, which argue against this explanation.	./cache/cord-309986-p7pqla6l.txt	./txt/cord-309986-p7pqla6l.txt
