Laboratory Studies. Most patients with parvovirus B19 (B19V) infection do not require laboratory studies because symptoms are mild and the illness resolves over 5-7 days. Parvovirus serology (anti-parvovirus B19 immunoglobulin M [IgM] and immunoglobulin G [IgG] antibodies) can be determined using enzyme-linked immunoassay (ELISA.

Une sérologie permet d'effectuer la r echerche d'une exposition à un agent pathogène, son état d'immunisation et potentiellement son état de protection. " En fonction du type profil d'immunoglobines trouvée (IgG et/ou IgM) et du type de sérologie, on peut savoir si l'infection est aigüe (donc en cours) ou ancienne " explique le Dr Kuentz.

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.

In pregnant women exposed to parvovirus B19, obtain IgG and IgM serology as soon as possible following exposure - Negative IgG and IgM results indicate that the mother is not immune and that no evidence of acute infection is noted. In this case, repeat the tests in 3 weeks. In patients with clinically significant anemia or transient aplastic.

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.

The prevalence of parvovirus B19 IgG antibodies increases with age. The age-specific prevalence of antibodies to parvovirus is 2-9% of children under 5 years, 15-35% in children 5 to 18 years of age, and 30-60% in adults (19 years or older).. Likely non-specific false positive IgM reactivity.

Le test parvovirus B19 IgG peut être prescrit accompagné du test parvovirus B19 IgM. Si les IgG et IgM sont positifs, il est possible que la personne testée soit en infection active ou ait eu une infection récente au parvovirus B19. Si seulement les IgM sont positifs, l'infection est possiblement en cours de développement.

Le parvovirus B19 est virus à ADN monocaténaire qui entraîne une suppression transitoire de l'érythropoïèse qui est légère et asymptomatique, sauf chez l'enfant qui présente des hémoglobinopathies sous-jacentes (p. ex., une drépanocytose) ou d'autres troubles des globules rouges (p. ex., une sphérocytose héréditaire) et qui peuvent provoquer des crises aplasiques transitoires.
Parvovirus B19 symptômes et traitements
Background: Human Parvovirus B19 (B19V) is a DNA virus, transmitted through respiratory secretions, hand-to-mouth-contact, blood transfusion and trans-placental transfer.It causes high mortality and morbidity in pregnant women, thus contributing to poor maternal and child health. B19V has been neglected due to dearth of epidemiological data.

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.

Positive for IgM (irrespective of the IgG result), this suggests recent infection with parvovirus B19, and the diagnosis is confirmed by testing an antenatal booking blood sample or a repeat blood test after 7-10 days. Seek specialist advice on any additional testing needed. Rubella infection (if the woman is not known to be immune).
