[The nephelometric method in the study of the hyperlipoproteinaemia: comparative analysis with chemical and electrophoretic methods (author's transl)].

On 814 subjects the cholesterolemia, the triglyceridemia and serum lipoproteins were determined; also the nephelometric analysis of the serum was conducted. The statistical analysis of the results allowed the following conclusions. 1) Approximately 98% of the pathological results are found in 3 types: type IV (about 49%), IIa (about 40%), IIb (about 11%). 2) The nephelometric determination of the M particles is particularly useful in the distinction between types IIa and IIb, because in type IIb there are pathologically increased values also when the triglycerides are normal or almost normal. There exists a significant correlation between the M particles determined by nephelometric analysis and the triglycerides determined by chemical methods.
