Pediatric Collection/Transport: 0.1 mL serum or plasma at 2-8°C.

Remarks: Separate serum or plasma from cells ASAP. Acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Please mark specimen plainly as "acute" or "convalescent."  

Unacceptable Conditions: Heat-inactivated, hyperlipemic, icteric, hemolyzed, or contaminated serum specimens.

Stability: After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

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.
