CDC researchers analyze the earliest batch of COVID-19 tests

The earliest batch of COVID-19 tests distributed by the US Centers for Disease Control and Prevention (CDC) exhibited false positive reactivity of negative controls due to flaws in assay design and contamination in one of the assay components, according to a CDC internal investigation published this week in the open-access journal PLOS ONE.

Eating before saliva collection may interfere with detection of SARS-CoV-2

A new study, published on the medRxiv* preprint server, has aimed to determine if children's diet impacts the detection of SARS-CoV-2 virus in saliva. Scientists performed diagnostic tests to detect this virus using real-time self-collected specimens provided by five healthy children. The samples were collected before and after eating selected foods. The specific time of collection of samples after eating were 0 minutes, 20 minutes, and 60 minutes after eating.
