​Beginning April 13, 2020, APHL has conducted a weekly survey of up to 100 state, local and territorial public health laboratories (PHLs) to collect the status of current and projected capability and capacity of laboratories to test for SARS-CoV-2, the virus that causes the Coronavirus Disease (COVID-19). Data from this survey is used to inform HHS, FEMA, CDC and other federal partners to support public health laboratory supply and reagent needs. ​​

Below is a dashboard of high-level data from this survey, updated weekly with the previous week's data. PDF versions of the weekly reports are also available on the left side of the page.
