Abstract：
:Whole blood electrical aggregometry (WBEA) has become an accepted method to gain quick information on platelet disorders. Compared to the optical method WBEA is closer to physiology and less complicated, but on the other hand more difficult to standardize. Different approaches have been attempted in the past to improve the reliability and practicability of this technique. The influence of sample age has not been defined so far. In a first step a mathematical modelling program was established, which is able to characterize the aggregation curves obtained after collagen stimulation. In a mathematical analysis various characteristics of the curve function were calculated and their sensitivity for aging investigated. Regression was performed for each characteristic, and correction factors defined. Our results indicate, that whole blood specimen for collagen induced aggregation can be used without correction factor up to 30 minutes. Data obtained with an age exceeding half an hour have to be corrected following a quadratic regression.
