Test Details
Methodology
Enzyme immunoassay (EIA)
Result Turnaround Time
1 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Test Includes
Human parvovirus B19, IgG; human parvovirus B19, IgM
Use
Differential diagnosis of acute or recent infection from past infection with human parvovirus associated with erythema infectiosum (fifth disease), aplastic crisis, and fetal infection
Custom Additional Information
IgM antibodies are detectable two weeks after exposure. IgG antibody production usually occurs 18 to 24 days after exposure. The presence of IgM antibodies to parvovirus B19 provide definite evidence of recent infection.
