title: Factor-VIII-related antigen: measurement by enzyme immunoassay.
abstract: Factor-VIII-related antigen was measured, both by an enzyme immunoassay using a microplate method and by the Laurell technique, in normal people, patients with von Willebrand's disease, haemophiliacs, and obligatory haemophilia carriers. The enzyme immunoassay was simpler to perform and gave equally reliable and reproducible results. Many more assays could be carried out at any one time.
