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.

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.

Minimum Volume. 0.5 mL serum. Additional Information. 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% to 35% in children 5 to 18 years of age, and 30% to 60% in adults (19 years or older).

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 symptômes et traitements

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.

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.
