If both IgG and IgM are positive, then this indicates recent infection within 7-120 days and the fetus is at risk of B19 transmission. If IgG results are negative with positive IgM results then that indicates acute infection with no previous antibodies against B19 and the fetus is at greater risk as the mother is not immune.

Parvovirus B19 Antibodies, IgG and IgM, Serum. Serologic detection of recent or past parvovirus B19 infection. This assay may be used to determine the serostatus of patients at risk for infection with parvovirus B19. Alongside clinical evaluation and other laboratory findings, results may be used to determine if the patient has recent or past.

The virus. B19V, a member of the Parvoviridae family, Parvovirinae subfamily, Erythroparvovirus genus, and Primate erythroparvovirus 1 species 10, is a small non-enveloped DNA virus, discovered in 1975 by Yvonne Cossart in the blood of a healthy blood donor 11.The name parvovirus originates from the Latin word parvum, which means small.In fact, parvoviruses are among the smallest known viruses.

Parvovirus B19 is a common infectious disease that spreads from person to person and most often results in no or very mild symptoms. The virus sometimes targets the cells that mature into red blood cells. Infection causes a temporary stoppage of the production of these cells. The effect of this stoppage is only apparent in individuals who don.

VirusHost Interactions of Enteroviruses and Parvovirus B19 in Myocarditis
Parvovirus B19 (B19V) is a member of the family Parvoviridae, genus Erythrovirus.B19V-specific IgG and IgM react differently against conformational and linear epitopes of VP1 and VP2 antigens, leading to the development of IgG avidity and epitope type specificity (ETS) enzyme immunoassays (EIAs) for distinguishing past from recent infection.

Parvovirus B19. Parvovirus B19 is part of a family of viruses that can cause infection. Most parvoviruses infect animals, such as cats and dogs. People cannot get infected with these parvoviruses. Dogs and cats can get vaccinated to protect them from parvoviruses that commonly affect them. Parvovirus B19 only infects people.
