A battery of tests to determine SARS-CoV-2 immune status:

1. The Abbott Architect SARS-CoV-2 IgG assay, run under an emergency use authorization from the FDA, is a qualitative test designed to detect IgG antibodies to the nucleocapsid protein of SARS-CoV-2.
2. The Abbott Architect SARS-CoV-2 IgG II assay, run under an emergency use authorization from the FDA, is a quantitative test designed to detect IgG antibodies to the spike protein of SARS-CoV-2 in serum and plasma.

Ordering: We are pleased to perform serology testing for all patients who have a valid provider order. We recommend outside providers arrange to have their patients' blood drawn at their usual clinical draw sites and sent to the lab, preferably after contacting Client Support Services at commserv@uw.edu to facilitate testing.

For patients who do not regularly seek care within UW Medicine, our phlebotomists at the University of Washington Medical Center-Northwest Campus (UWMC-NW) and UWMC-NW Outpatient Medical Center (OPMC) located on Meridian Ave. N. are able to perform blood draws for testing with a valid provider order.
