title: [Evaluation of methods of studying hemostasis].
abstract: Comparative assessment of the methods for studies of platelet aggregation, used in the USSR and in Hungary, has demonstrated the usefulness and reproducibility of both. The reagents manufactured by Reanal (Hungary) are characterized by a higher sensitivity, inducing a more distinct and rapid formation of aggregates. This fact is of particular importance when no aggregometers are available and the 'snow whirl' is assessed visually. Another advantage of the Hungarian aggregants is the presence of the whole set of reagents in the kit and standardization of these reagents. Assessment of the activated partial thromboplastin time of mixed donor native plasma with the use of the Soviet native partial thromboplastin stored frozen and with the use of the Reanal reagent has demonstrated a high variability of the results; this may be explained by the employment of nonstandard reference plasma. The advantages of the imported lyophilized reagent are a year's shelf life and the possibility of transportation.
