|CERNER / EPIC MNEMONIC: |
|CPT CODE: |
|TEST INFORMATION: |
This test includes testing for IgG and IgM antibodies to Parvovirus B19
|DAYS PERFORMED: |

|REJECTION CRITERIA: |
Excessive hemolysis, gross contamination of specimen, chylous serum, improper storage of specimen, inappropriate specimen container, insufficient specimen volume.
|MINIMUM VOLUME: |
5 mL blood (1mL serum)
|HANDLING INSTRUCTIONS: |
Specimen should be transported as soon as possible. When transportation is delayed, refrigerate.
|REFERENCE RANGE: |
Parvovirus B19 AB IgG = <0.9, Parvovirus B19 AB IgM = <0.9 Refer to Quest Test Code 8946.
Enzyme Immunoassay (EIA)
|REFERRAL LABORATORY: |
|ADDITIONAL INFORMATION: |
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.
