Description

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. Results are reported as AU/mL. Per manufacture’s package insert protective level is ≥50.0 AU/mL.
