title: [Application of the time-resolved immunofluorometric assay in the detection of viruses].
abstract: Two systems of time-resolved immunofluorometric assay (TR-IFMA), i.e., LKB system detection of viruses. The viruses detected were mainly adenovirus, influenza virus, parainfluenza virus, respiratory syncytial virus rotavirus, hepatitis B virus, human immunodeficiency virus, rubella virus, etc. Compared with methods of ELISA and RIA, TR-IFMA has the merits of high sensitivity, specificity and consistency with clinical diagnosis. The low detection limit of virus antigen by TR-IFMA is between 10-100 pg. The application of dual-label TR-IFMA also showed good effect. TR-IFMA can also be used in the detection of viral nucleic acids. The target region detected may reach the level of pg.
