[The hemolysis index as quality indicator for extra-laboratory part of preanalytical phase].

The article considers the new indicator of quality - percentage of samples with hemolysis of free hemoglobin in blood serum lesser than 500 mg/l that corresponds the index of hemolysis lesser than 50 measured using analyzer VITROS 5.1FS (Ortho-clinical diagnostics, USA). The indicator basically is related to quality of implementation of extra-laboratory section of pre-analytical stage of laboratory analysis namely drawing and transportation of blood. This indicator is especially valuable for laboratories charged with organization of samples drawing and transportation at particular territory. The first attempt is made to determine the requirements to quality according this indicator. The optimal level of quality, is the percentage of samples with hemolysis index less than 50 is lower 6.4%. acceptable - 6.4%-8.6%, minimal - 8.7% - 10.9%. The percentage af samples more than 10.9% corresponds to unacceptable level of quality.
