Interpretive Data
Component | Interpretation |
---|---|
Parvovirus B19 Antibody, IgG | 0.90 IV or less: Negative - No significant level of detectable Parvovirus B19 IgG antibody. 0.91-1.09 IV: Equivocal - Repeat testing in 7-21 days may be helpful. 1.10 IV or greater: Positive - IgG antibody to Parvovirus B19 detected, which may indicate a current or past infection. |
Parvovirus B 19 Antibody, IgM | 0.90 IV or less: Negative - No significant level of detectable Parvovirus B19 IgM antibody. 0.91-1.09 IV: Equivocal - Repeat testing in 7-21 days may be helpful. 1.10 IV or greater: Positive - IgM antibody to Parvovirus B19 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. |
