Parvovirus IgM
Description:
Qualitative chemiluminescent immuno-assay for Parvovirus IgM antibodies. Test used for the diagnosis of primary parvovirus infection. Tested together with parvovirus IgG. Reliable following onset of rash in immunocompetent individuals. DNA testing may be required in immunocompromised hosts, sickle cell disease and pregnancy. This assay is available routinely Mon to Fri.
This test is not UKAS accredited

Clinical details:
Prodrome
Fever
Slapped cheek disease in children
Fine, erythematous maculopapular rash
arthralgia.arthropathy
Depressed reticulocyte count and fall in Hb
- Sickle cell/haemoglobinopathy patients may present with aplastic crisis during prodrome, before rash/arthropathy and serological response develop.
- Immunocompromised patients may present with anaemia (or pancytopenia) during prodrome, without development of rash/arthropathy or detectable antibody response.
- Parvo IgM may clear after one month, therefore parvo IgG alone may be detected following primary infection in pregnancy. Needs careful assessment
