| Reference Interval: |
|
0.89 IV or less: Negative - No significant level of detectable Parvovirus B19 IgG antibody. 0.90-1.10 IV: Equivocal - Repeat testing in 10-14 days may be helpful. 1.11 IV or greater: Positive - IgG antibody to Parvovirus B19 detected, which may indicate a current or past infection. |
| Interpretive Data: | |
|
The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
