Reference Range

Note: The magnitude of the measured result, above the cutoff, is not indicative of the amount of anitbody present. The presence of CMV IgM should also be determined to assess the stage of the CMV infection. Diagnosis of infectious diseases should not be established on the basis of a single test result, but should be determined in conjunction with clinical findings and other diagnostic procedures as well as in association with medical judgement. Diseases such as Epstein-Barr viral syndrome, toxoplasmosis and hepatitis may cause symptoms similar to CMV infection and must be excluded before confirmation of diagnosis.

U/mL	Value	Result Interpretation
Below 0.6	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 sample should be collected and tested no less than one or two weeks later.
0.6-0.69	Equivocal	The equivocal sample should be repeat tested. In case the result remains in this range after repeat testing, a second sample should be collected.
Equal or Above 0.7	Positive	Presence of detectable CMV IgG antibodies. A positive result generally indicates either recent or past exposure to CMV
