Quality of the analyze from a blood sample are often related to hemolysis. Hemolysis of blood is reality everywhere and cannot be eliminated but can be reduced. There is no exact way to avoid hemolysis but there is some precautions which can help to reduce the hemolysis.
Hemolysis is happening before stabilizing of the blood by a centrifuge so one thing is the time from the blood are tapped to the blood sample is centrifuged. Another thing that may affect the hemolysis process is the temperature.
G-forces has very often been one of the suspected criteria for hemolysis but a recent study from Greifswald University Hospital where they tested the effect of transporting blood samples in pneumatic pipe systems like Tempus600 showed that even when the blood samples was exposed for 16 G there was no hemolysis. But on the other hand there can be hemolysis of a blood sample even if the sample are dropped once on a table. It seems like the sudden shake or G-effect on a blood samples are worse than a high steady G-effect.
The importance of reducing hemolysis is very high grounded to the conclusion of the economic costs when a blood sample are rejected because of quality. The patient needs to come again, the staff needs to tap the blood again, the blood sample needs to be transported and this cycle is very time demanding and have high costs.
The conclusion of how to remove hemolysis totally is not possible, there will always be some kind of hemolysis but if the blood samples are stabilized fast and transported with care there is a significant low occurrence of hemolysis.
