The National Reference Center for Hantavirus in Belgium is currently using the Hantavirus IgM/IgG ELISA Progen kit (Heidelberg, Germany) for the detection of the most prevalent Hantavirus in Western Europe, Puumala virus (PUUV). Two commercially available PUUV kits were compared: Progen and RIDASCREEN® Hantavirus Puumala IgM/IgG ELISA assay (Darmstadt, Germany). The sensitivity was evaluated with a panel of 68 samples from patients with an acute infection (n = 44) or a past infection (n = 24). Specificity was evaluated with a panel of 62 samples from patients with potentially false borderline results (n = 7) (no seroconversion), seronegative samples (n = 25) and potentially cross reacting samples (n = 30). Discordances were resolved by immunoblot. Substantial agreement was calculated using Cohen kappa coefficient. The RIDASCREEN® kit showed a higher specificity (IgM: 94.3%; IgG: 94.4%) than the Progen kit (IgM: 77.0% IgG: 93.0%). The sensitivity for IgM ELISA was 100% for both assays. IgG sensitivity was, respectively, 98.3% and 100% for Progen and RIDASCREEN®. A Cohen kappa coefficient of 0.76 and 0.90 was found between Puumala IgM and IgG, respectively. This study showed a higher specificity for the RIDASCREEN® kit than the Progen kit, while the sensitivity was as good as for the Progen kit.

D003429 Cross Reactions Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen. Cross Reaction,Reaction, Cross,Reactions, Cross
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D018778 Hantavirus Infections Infections with viruses of the genus ORTHOHANTAVIRUS. This is associated with at least four clinical syndromes: HEMORRHAGIC FEVER WITH RENAL SYNDROME caused by viruses of the Hantaan group; a milder form of HFRS caused by SEOUL VIRUS; nephropathia epidemica caused by PUUMALA VIRUS; and HANTAVIRUS PULMONARY SYNDROME caused by SIN NOMBRE VIRUS.

D029262 Puumala virus A species of ORTHOHANTAVIRUS causing nephropathia epidemica, a mild form of HEMORRHAGIC FEVER WITH RENAL SYNDROME. It is found in most of Europe and especially in Finland, along with its carrier rodent, the bank vole (Clethrionomys glareolus).
