FEATURED AACC ARTERY DISCUSSION

False Positives Rapid Testing in Hospital

One Artery user has a COVID-19 patient who, after three weeks of hospitalization, tested negative for SARS-CoV-2 in the central lab, but tested positive with a rapid test. He is wondering how to determine if the positive result is false and if he should retest the patient. A respondent pointed out that CDC no longer recommends a test-based strategy for discontinuing transmission-based precautions, even for hospitalized patients, because persistence of SARS-CoV-2 PCR positivity does not generally correlate with infectiousness. Instead, CDC recommends using symptom- and time-based determinations to determine if a patient is still infectious.
