Parvovirus B19 (Human), IgG, IgM
Also known as: Human Parvovirus B19, IgG, 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
Special Instructions
The test uses an enzyme immunoassay (EIA) methodology to detect IgG and IgM antibodies to human parvovirus B19. Turnaround time is typically 1 to 5 days from specimen pickup to result release. Testing schedules may vary, and additional time may be required for confirmatory or reflex tests.
Limitations
The test results are dependent on the quality of the specimen submitted. Hemolysis, lipemia, or gross bacterial contamination can lead to sample rejection. Cross-reaction with other antibodies or immunoglobulin classes, technical issues, or sample interference may also affect the results, potentially leading to false positives or negatives. The specific sensitivity and specificity of the test are not provided.
