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)
Storage/Transport Temperature
Refrigerated.
Stability (from collection to initiation)
After separation from cells:
Room temperature (15 to 30°C) – 2 days
Refrigerated at 2‑8 °C - 7 days
Frozen (- ≤20 °C) – Longer stability
Cerner Orderable(s)
COVID 19 IgM Antibody
Performed
St. Joseph's Hospital
Methodology
Chemiluminescent
Reported
Within 24 - 48 hours.
Synonyms
SARS-CoV-2
Reference Interval
Negative
Interpretive Data
Comment: This test detects IgM 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.
