Interpretation

Application

Acute parvovirus B19 infection causes erythema infectiosum or fifth disease (slapped cheek).

 

Parvovirus DNA detection is suitable in the following situations:

1. Human parvovirus B19 antibodies are not detectable in some immunocompromised patients with chronic and persistent infection.

2. Diagnosis of infection for prenatal diagnosis of non-immune fetal hydrops.

3. During aplastic crisis parvovirus IgM antibodies may not be present until some days after crisis onset. DNA testing may be useful.

 

Serology is recommended in immunocompetent individuals, including pregnant women, patients with erythema infectiosum or transient aplastic crisis.

 

Interpretation

PCR performed on serum is useful for the recognition of chronic parvovirus (aplastic anaemia) B19 infection in immunocompromised individuals.

 

PCR performed on amniotic fluid or fetal blood can be useful for the diagnosis of inter uterine infection. Detection of parvovirus B19 in these specimens is presumptive evidence of fetal infection, but does not provide information about the consequences of the infection.

 

Parvovirus B19 DNA can also be detected in the peripheral blood of almost all patients with fifth disease.

 

Parvovirus B19 can be detected by PCR in serum, urine, CSF, pleural fluid, respiratory secretions, peripheral mononuclear cells, bone marrow cells, tissue, synovial fluid, joint aspirates and amniotic fluid.
