Result Interpretation

<0.60 AU/mL (negative):  Absence of detectable CMV IgG antibodies. A negative result generally indicates that immunity has not been acquired. If exposure to CMV is suspected despite a negative finding, a second specimen should be drawn and tested on <1 to 2 weeks later.)
 
0.60-0.69 AU/mL (equivocal):  The equivocal specimen should be repeat tested. In case the result should remain in this range after repeat testing, a second specimen should be drawn.)
 
≥0.70 AU/mL (positive):  Presence of detectable CMV IgG antibodies. A positive result generally indicates either recent or past exposure to CMV.)
