Analysis of different variants of erythrocyte survival using digital computers

In the paper a method is presented, enabling parameter estimation of erythrocyte survival patterns, what is an important element in the diagnosis of haemolytic anaemias. The method is based on a computer program, fitting the experimental data to eight variants of theoretical patterns with use of a weighted least squares criterion. A simple statistical test of approximation quality is described and several interpretational examples are given. The program may be easily handled by a physician with small programming experience.
