METHOD FOR QUANTITATIVE DETERMINATION OF BLOOD ERYTHROCYTE Russian patent published in 2004 - IPC

FIELD: medicine, laboratory diagnosis. SUBSTANCE: method provides the permanent retention of amount of potassium ions that makes ability to determine erythrocytes in samples of hemolyzed blood up to 6 months after blood samples taking off for analysis. Blood sample is hemolyzed with 1.25% Triton X-100 solution in dilution 1:10, respectively, followed by determination in blood sample of potassium ions content in ion-selective analyzer device and amount of erythrocytes in 1 l of whole blood (A) is measured by the formula: A = Cex/Cs*X wherein Cex is content of potassium ions in experimental sample as mmole/l; Cs is content of potassium ions in standard sample as mmole/l; X is amount of erythrocytes in 1 l of blood of standard sample. EFFECT: improved method for determination. 2 tbl
