[On the importance of new test of HDL-cholesterol in lipoid diagnostics with geriatric patients (author's transl)].

1. By introducing a HDL-cholesteroltest in the multiple screening we have the chance to valuate the diagnostical validity of the test value of triglycerides, total cholesterol and HDL-Cholesterol and of the calculated value of LDL-cholesterol and ratio HDL/LDL-cholesterol. 2. We studied the incidence of lipoid findings of 210 patients by graphical statistics. 3. The test values of triglycerides, total cholesterol and HDL-cholesterol manifest a mixed collection with a graph having different maximums whereby statistically a "normal" population can be differentiated from a "pathological" population. 4. The calculated value LDL-cholesterol is normal distributed, the ratio HDL/LDL-cholesterol is logarithmic normal distributed. The causes therefore are statistic effects.
