METHOD OF OPTICAL ANALYSIS OF THROMBOCYTE AGGREGATION Russian patent published in 2011 - IPC G01N33/49 

FIELD: medicine.

SUBSTANCE: in a cell containing an agitated blood sample, a primary measuring channel is formed by means of a collimated narrow optical beam. Then a photoconverter is used to register light intensity through the primary and to isolate thereafter constant and variable electric signal components, and to determine a mean value of thrombocyte aggregates. Immediately before completion of sample agitation, a mean I_CK light intensity through termination the primary measuring channel formed in the cell at the bottom of the sample. On completion of agitation, an additional measuring channel similar to the primary one is formed at the top of the sample near to its level wherein time-stable light intensity value I_y is registered. A logarithm of the relation I_y/I_CK shows a degree of aggregation.

EFFECT: invention enables measurement of the same sample both of mean aggregate value, and the degree of thrombocyte aggregation, and more accurate evaluation of these characteristics.
