Abstract

The invention encompasses an immunoassay technique based on the agglutination of two different particles having measurably different properties and coated with a substance specifically bindable to a substance to be determined. The agglutination is measured by using an optical or electrical counter, such as those designed to count blood cells, to measure the aggregate formed by measuring a distinct property associated with each particle, generally, size and fluorescense.
