title: Determination of influenzavirus neuraminidase inhibition titres.
abstract: Representatives of the WHO influenza programme recently proposed a standard method of determining neuraminidase activity and neuraminidase inhibition (NI) antibody titres. Logit transformation of the data obtained with the WHO method for the NI assay permits a more efficient performance of the test and easy calculation of titres with a computer programme.
