Aid in discriminating between current and past cytomegalovirus infection in immunocompetent individuals.
Semi-Quantitative Chemiluminescent Immunoassay
New York DOH Approval Status
Serum Separator Tube (SST).
Allow specimen to clot completely at room temperature. Separate from cells ASAP or within 2 hours of collection. Transfer 2 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens.
Plasma or urine. Contaminated, hemolyzed, or heat-inactivated specimens.
Label specimens plainly as "acute" or "convalescent."
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|CMV Antibody IgM||29.9 AU/mL or less|
|Cytomegalovirus Antibody, IgG||0.59 U/mL or less: Not Detected.
0.60-0.69 U/mL: Indeterminate - Repeat testing in 10-14 days may be helpful.
0.70 U/mL or greater: Detected.
|Cytomegalovirus Antibody, IgM||29.9 AU/mL or less: Not Detected.
30.0-34.9 AU/mL: Indeterminate - Repeat testing in 10-14 days may be helpful.
35.0 AU/mL or greater: Detected - IgM antibody to CMV detected, which may indicate a current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.
This test should not be used for blood donor screening, associated re-entry protocols, or for screening Human Cell, Tissues and Cellular and Tissue-Based Products (HCT/P).
