Introduction: Hemolysis is the commonest causeof pre analytical error. Hemoglobin released interferes with analyte concentration chemically and optically.

Analytical – theoretical study on SWTs in terms of pre-selection of the aero layouts best suited for further optimization

to assess the effects of pre-analytical handling (storage time and temperature) on selected hematological parameters, whole blood samples were collected in edta coated tubes from each of 30 clinically normal male adult beagle dogs. each sample was separated in 2 aliquots, of which one was stored in ambient temperature (25 ˚c) and the other one was refrigerated (2 to 4 ˚c). complete blood counts...
