[Evaluation of the usefulness of the ELISA method for determining the level of enterovirus antibodies in serum and cerebrospinal fluid]

Abstract

The usefulness of the methods was compared: complement fixation test (CFT), neutralization test (NT) and ELISA IgG and IgM against enteroviruses for the evaluation of specific immune reaction in sera and cerebrospinal fluid (CSF) samples of patients with confirmed enterovirus infections. The criteria were established for the assessment of ELISA results in rapid diagnosis of enterovirus neuroinfections. The criteria accepted by the producer lowered the sensitivity of the method and the possibility of recognition of local synthesis of antibodies in the CNS. The use of serum negative in CFT and negative CSF as reference for the determination made possible using of that kit for rapid diagnosis of neuroinfections. The modified ELISA IgG test makes possible determination of antibodies in CSF and serum, and accepting the generally recognized criteria for local production of antibodies in the CNS the ELISA test makes possible rapid diagnosis of neuroinfections which is not possible by other methods.
