Hemolyzed tube

WebA hemolyzed test result or ‘hemolysis’ can happen when the red blood cells in the sample burst. When this happens, it is usually not possible to get a test result. Hemolysis can happen with any blood tests, regardless of the method of blood collection (eg. finger prick sample or venous blood draw) and where it was collected (eg. at the ... WebHemolysis can be caused by rough handling of a blood specimen, leaving the tourniquet on too long (causing blood stasis) or squeezing the tip of the finger too hard during capillary collection, dilution, exposure to contaminants, extremes in temperature, or pathologic conditions. The primary purpose of the white cells is to fight infection.
