|CERNER / EPIC MNEMONIC:|
This test includes testing for IgG and IgM antibodies to Parvovirus B19
Monday - Friday
3 - 7 days
It is the responsibility of the requesting physician to see that both acute and convalescent specimens are obtained. The physician should arrange for the collection of the convalescent serum 14- 28 days after the acute is collected. Paired testing of acute and convalescent phase sera is recommended, if clinically indicated.
Red top Vacutainer tube or SST tube
Excessive hemolysis, gross contamination of specimen, chylous serum, improper storage of specimen, inappropriate specimen container, insufficient specimen volume.
5 mL blood (1mL serum)
Specimen should be transported as soon as possible. When transportation is delayed, refrigerate.
Parvovirus B19 AB IgG = <0.9, Parvovirus B19 AB IgM = <0.9 Refer to Quest Test Code 8946.
Enzyme Immunoassay (EIA)
This test determines the presence of Parvovirus B19 infection which can cause Fifth disease in children, aplastic anemia in immunocompromised individuals, aplastic crisis in chronic hemolytic anemia patients, and "Lyme-like" arthritis in the absence of serological evidence of B. burgdorferi infection. Specific IgG antibodies are usually detected in 2-3 weeks after exposure, reach peak concentrations, and then decline, but remain detectable for years. Specific IgM antibodies are detected 1-2 weeks after exposure, reach peak concentrations and then decline to undetectable concentrations within 2-3 months after exposure.
