A Cautionary Tale of False-Negative Nasopharyngeal COVID-19 Testing	2020-05-05		.txt	text/plain	944	62	52	We present the case of a patient that, based on known exposure to a COVID-19 positive family member, typical symptoms, suggestive labs, and consistent imaging, had a high pre-test probability of having COVID-19, yet tested negative on two successive NP RT-PCRs. Only on the third COVID-19 sample, taken from sputum, was the patient ultimately correctly diagnosed. Based on these observations, the authors theorized a de-isolation protocol that not only considers date from symptom onset as is suggested by CDC (7), but also viral load. In patients with a high pre-test probability of COVID-19, a single negative NP RT-PCR may be insufficient to rule-out disease.
