Description

1. This assay is used for quantitative detection of specific IgM antibodies to TORCH in serum samples. 2. Positive result for TORCH IgM indicates possible acute infection with TORCH. False positive reaction due to rheumatoid factor and persistence of positive IgM (except Herpes Simplex virus) for upto 2 years is not uncommon. 3. Negative result indicates no serological evidence of infection with TORCH. False negative can be due to immunosuppression or due to low/undetectable level of IgM antibodies. A suspected diagnosis of acute TORCH infection should be confirmed by PCR analysis or repeat test after 10-14 days.
