Hemolysis problem, Bad habits during blood collection can cause the following hemolysis:
1) During blood collection, the positioning or needle insertion is not accurate, and the needle tip probes around in the vein, resulting in hematoma and blood hemolysis.
2) Excessive force when mixing test tubes containing additives, or excessive action during transportation.
3) Take blood from a vein with a hematoma. The blood sample may contain hemolytic cells.
4) Compared with the additives in the test tube, the blood collection is insufficient, and hemolysis occurs due to the change of osmotic pressure.
5) The venipuncture is disinfected with alcohol. Blood collection is started before the alcohol is dry, and hemolysis can occur.
6) During skin puncture, squeezing the puncture site to increase blood flow or sucking blood directly from the skin can cause hemolysis.
