title: [THE PERCENTAGE OF BLOOD SERUM TESTS WITH HEMOLYSIS IN DIFFERENT GROUPS OF PATIENTS].
abstract: In the process of laboratory analysis most of the errors occur at the pre-analytical stage. The percentage of blood serum tests with hemolysis is largely applied as an indicator of quality of sampling and transport of blood tests in laboratory. The study was carried out to analyze percentage of tests with hemolysis in different groups of in- and out-patients. The percentage of tests with hemolysis was estimated according actual recommendation of IFCC working group "Laboratory Errors and Patient Safety" as percentage oftests with free hemoglobin more than 0.5 g/l of total amount of serum tests analyzed on biochemical analyzer capable to measure hemolysis index. The hemolysis was identified in 199 (1.4%) out of 14 170 samples. The large dispersion of results in different groups of patient was established. In children younger than 7 years treated in hospital percentage of hemolysis amounted to 2.44%, in patients of reanimation department - 2.38%. In adult patients of hospital this indicator of quality ranged from 0.31% to 1.59%. In two groups of out-patients this indicator amounted to 0.36% (clinic personnel, dispensarization) and 1.81% (out-patients). Such a dispersion complicates inter-laboratory comparison of quality according this particular indicator. The necessity is substantiated to apply more efforts concerning harmonization of indicators of quality in laboratory medicine.
