Werkwijze voor het opsporen van antigenen in lichaamsvloeistoffen, en een hierbij toegepast reagens.

摘要

A highly sensitive direct particle agglutination test capable of routinely detecting as little as 0.2 nanograms of antigen per milliliter of clinical fluid and characterized by uniform sensitivity as well as stability is disclosed as well as coated particles having a sensitivity of 0.2 nanograms antigen per milliliter and methods for preparing such coated particles. In addition, a method to reduce the frequency of non-specific agglutination with human sera to 2% or less is described.
