[Evaluation of thrombocyte retractile activity using a retractograph].
Direct measurement of the force of clot contraction from the plasma in normal subjects and standardization of plasma platelet count, carried out with a retractograph, a newly designed apparatus, have helped assess the platelet retractile activity. Linear relationship between platelet count in the clot from the plasma and the force of the clot contraction, detected in normal subjects, allows one to do without standardization of the platelet count to a preset level when measuring the blood platelet retractile activity in patients.
