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.


A Niche for HbA1c Testing in Youth

Glycated hemoglobin and fasting plasma glucose levels performed equally in detecting hyperglycemia according to current screening criteria, but HbA1c better identified youth at higher long-term cardiometabolic risk.
