Evaluation of a Commercial DNA Enzyme Immunoassay for Detection of Enterovirus Reverse Transcription-PCR Products Amplified from Cerebrospinal Fluid Specimens

We evaluated the DiaSorin DNA enzyme immunoassay (DEIA) kit for detection of enteroviral reverse transcription-PCR (RT-PCR) products amplified from cerebrospinal fluid. By use of an optical density of 0.05 as the absorbance cutoff, 35% of 198 specimens were PCR positive, whereas 16% were culture positive. DEIA was rapid and sensitive and can help implement enterovirus RT-PCR in clinical laboratories.
