[Is there interrelationship between percentage of hemolysis and clots in samples of venous blood?].

The most failures in the process of laboratory analysis occur at the pre-analytical stage. The percentage of samples of blood serum with hemolysis and percentage of samples of EDTA of whole blood with clots are largely applied as indices of quality of venous blood sampling. The analysis of data from 28 laboratories established no relationship between percentage ofsamples with hemolysis and percentage of samples with clots.
