Abstract
Methodology which avoids the problems associated with interference from whole blood is provided for instrumented determination of platelet binding function. Particularly, small particles to which fibrinogen is bound, and which contain an infrared light absorbing dye, are used to determine the binding of platelets in a whole blood sample to the fibrinogen. Agglutination of the platelets with the coated particles is determined by a change in infrared light absorption characteristics.
