When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: IA

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• SARS-CoV-2 (COVID-19) IgG+IgM Ab [Presence] in Serum or Plasma by Immunoassay
• SARS coronavirus 2 Ab.IgG+IgM
• Qualitative results for the detection of IgG and/or IgM antibodies against SARS coronavirus 2 (SARS-CoV-2), also known as the 2019 Novel Coronavirus (2019-nCoV), by immunoassay methods. The assay does not distinguish between IgG and IgM Ab so cannot differentiate between a recent and past infection. Testing is performed for the diagnosis of Coronavirus Disease 2019 (COVID-19).
