Reference Interval:
 
Test Number Components Reference Interval
0050165Cytomegalovirus Antibody, IgG 0.89 IV or less: Negative - No significant level of detectable CMV IgG antibody.
0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - IgG antibody to CMV detected, which may indicate a current or past CMV infection.
0050553Cytomegalovirus Antibody, IgM 0.89 IV or less: Negative - No significant level of detectable CMV IgM antibody.
0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - 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.
