Abstract

We compared washed nasal epithelial cells with unfractionated nasal secretions as sources of respiratory syncytial virus (RSV) antigens in an indirect enzyme-linked immunosorbent assay (ELISA). Of 28 infants positive for RSV by virus isolation or direct immunofluorescence or both, 27 (96%) were positive by ELISA with whole nasal secretions, whereas only 19 (68%) were positive by ELISA with the matching washed-cell fractions. Furthermore, the ELISA absorbances obtained with nasal secretions were significantly greater than those seen with washed-cell fractions, indicating that whole nasal secretions contain relatively greater amounts of RSV antigens as measured by ELISA.
