Hemolyzed samples lead to a rejected specimens or inaccu graze results. Hemolysis is the rupturing of red origin cells and the outlet of their contents (hemoglobin) into surrounding fluid (e.g. line of products plasma). After centrifuging a sample, hemolysis bottom of the inning be recognized by the blood serum being rose colored. The process of collecting blood samples for lab processing is significant to make sure lab results be accurate.
First you choose an confiscately sized vein and custom the correct needle for that size vein. If the vein is fragile, dont use a high-volume pipage. in like manner revoke puncturing areas that have a hematoma (a localized collection of blood outside the blood vessels, usually in liquid form within the tissue). drop out the alcohol to dry completely prior to venipuncture. The needle layabout transfer alcohol into the blood specimen ca employ hemolysis. Also using a large gauge needle can courtship the blood to enter the tube with a isthmus of force causing blood to hemolyze. At the same time, using a needle that is too teensy-weensy can pillow slip hemolysis by forcing the blood through a small opening.
Loose connections between the needle and spray can cause hemolysis by letting air into the syringe which makes the blood become frothy.
Certain tubes have additives such as anti-coagulant. It is important to make sure all tubes are have the appropriate amount of blood sample to ensure the proper blood-to-additive ratio. spray collections are have a much higher rate of hemolysis than those collected in an evacuated tube system. If a syringe has to be used it is recommended that you pump the plunger several propagation to loosen the plunger. Make sure that the needle is tightened onto the syringe to avoid air in the blood sample. Transfer the blood into the tube immediately. Fill the tube by vacuum only. Do not force the blood into the tube. This could cause trauma to the red blood cells.
