Subtitle: Common Causes of Hemolysis During Blood Collection
Hemolysis is the breakdown of red blood cells, leading to the release of their contents into the surrounding medium. This can occur during blood collection, and is a major concern for medical professionals. Hemolysis can cause medical complications, and can lead to inaccurate laboratory test results. To ensure that hemolysis does not occur during blood collection, it is important to understand what the common causes are. Below are five of the most common causes of hemolysis during blood collection.
Improper Collection Techniques
Using improper techniques when collecting blood samples can lead to hemolysis. This includes improper anticoagulant or preservative use, inadequate mixing of the sample, or incorrect storage temperatures. In addition, the needle used for collection must be of the proper size and not cause any physical damage to the red cells.
Contamination
Contamination of the sample with bacteria or other substances can cause hemolysis. This can be caused by the technician not following proper aseptic technique, or not using clean needles and collection containers.
Excessive Trauma
Excessive trauma to the blood sample can cause hemolysis. This includes excessive shaking or mixing of the sample, as well as using needles that are too large.
Improper Storage
Storing the sample at temperatures that are too high or too low can cause hemolysis. Samples should be stored at the recommended temperature, which is typically between 4 and 8°C.
Exposure to Chemicals
Exposure to certain chemicals, such as certain detergents, can cause hemolysis. These chemicals can be found in the collection containers, needles, or on the technician's hands. It is important to use only clean and sterile collection supplies to avoid hemolysis due to chemical exposure.
