Abstract

To determine the influence of oseltamivir phosphate (Tamiflu) on the results of microneutralization and hemagglutinin-inhibition (HI) tests in human sera with H5N2 influenza virus, ten volunteers were administered Tamiflu and blood samples were collected. In the microneutralization test, no consistent effects were observed. However, in the HI test, specimens from all volunteers taken at 4 and 7 h after drug administration showed a higher titer as compared to 0 and 24 h after administration when mammalian cells (horse, guinea pig, and human) were used. These results suggest that the administration of Tamiflu may affect the results of HI tests for H5N2 virus.
