Allow serum tube to clot completely at room temperature for a minimum of 20 mins. Separate serum from cells within 2 hours of collection. (Min: 0.3 mL serum or plasma)
If ordering test "COVID 19 IgG Antibody (NUCLEOCAPSID)", the provider must indicate specifically that the NUCLEOCAPSID is what they want to order.
If the provider writes "COVID IgG," the Spike protein assay, "COVID IgG Antibody, Spike, Semi-Quantitative," should be ordered.
Performed

Chemiluminescent
Reported
Within 24 - 48 hours.
Synonyms
SARS-CoV-2
Reference Interval
1.4 (Negative)
Interpretive Data
Comment: This test detects IgG antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has received Emergency Use Authorization (EUA) from the FDA. A negative result does not rule out active /recent COVID-19. Follow-up testing with a molecular test is recommended in symptomatic patients. A positive result suggests a recent infection with SARS-CoV-2. Infrequently, false-positive results may be due to prior infection with other human coronaviruses.
