Die spontane, standardisierte Thrombozytenadhäsion und -aggregation in der Zählkammer

Abstract

An easy, economic and standardised method of orientation about the 3 most important platelet functions, out of a small quantity of blood is described. In order to examine the reliability of this method a comparative study between the aggregation results in the counting chamber and the platelet aggregation test (PAT) according to BreddIN was carried out. To obtain an exact determination of aggregation in the counting chamber not only the classification into aggregation grades (visual criterium) was taken but also after counting the ‘free platelets’ the aggregation index (PAgI) according to Reuter et al. was calculated. The good concordance of the comparative results of these 2 technically totally different methods are discussed.
