[Redundancy reduction in laboratory studies--evaluated by the laboratory diagnostic follow-up program of an epidemiologic cardiovascular study].

In addition to our information about significant relations of certain laboratory parameters concerning probationers suspected of heart and vessel diseases, who were identified by means of x-ray screening (EBMO-Cor Berlin) is reported on laboratory parameters applied to follow-up examinations, which proved to be redundant for what was expected (referring the heart and vessel diseases). It refers to the parameters of total protein in the serum, serum electrophoresis, zinc-sulphate test, hematocrit and hemoglobin. The results are supported by mathematic--statistical returns. With regard to the exponential laboratory load in the result of screening and follow-up examination under suspicion of heart and vessel disease the necessity of such considerations is underlined. The statement gains in its significance by the original material concerning the population.
