COVID-19 Diagnostic and Antibody Tests

ARUP offers a nucleic acid amplification (NAA) test for the diagnosis of a current COVID-19 infection and an immunoglobulin G (IgG) antibody test (targeting nucleocapsid proteins) for the evaluation of exposure to SARS-CoV-2.

 

Diagnostic Test

SARS-CoV-2 (COVID-19) by NAA (3002638)

Clinical Use:

Recommended molecular test (NAA) to detect SARS-CoV-2 in symptomatic patients. Because symptoms of COVID-19 are similar to those of other respiratory infections, a clinical evaluation alone is not sufficient to make a COVID-19 diagnosis.

Benefits:

  • We offer a rapid turnaround time.
  • ARUP’s molecular assays are designed to detect several SARS-CoV-2 RNA gene targets, allowing for the detection of COVID-19 variants.
  • We accept multiple specimen types, including nasopharyngeal swabs, oropharyngeal swabs, nasal swabs, and saliva specimens.

Antibody Test

COVID-19 IgG, Qualitative by CIA (3002776)

Clinical Use:

Use for the qualitative detection of IgG antibodies against the nucleocapsid protein of SARS-CoV-2 that develop in response to natural infection with SARS-CoV-2 (COVID-19 infection). These antibodies do not develop as a result of a COVID-19 vaccination.

Benefits:

  • Our highly sensitive and specific assay detects low levels of IgG antibodies.

Vaccine-Induced Immune Thrombotic Thrombocytopenia

Unusual thrombotic events with thrombocytopenia have been reported in a small number of patients following receipt of two SARS-CoV-2 vaccines (AstraZeneca and Johnson & Johnson/Janssen).
