What does a "hemolyzed blood sample" indicate?

A hemolyzed blood sample indicates that the red blood cells within the sample have ruptured, leading to the release of hemoglobin and other intracellular components into the surrounding plasma. This phenomenon can occur due to various factors, such as mechanical trauma during blood draw, improper handling, or the presence of certain antibodies. Hemolysis can significantly impact laboratory results, as it can influence the concentration of various analytes. For example, it can lead to falsely elevated levels of potassium and other substances that may be present in higher concentrations within the red blood cells than in the plasma.

The other options, while they indicate potential issues with blood sampling or the health of the donor, do not accurately describe the specific condition of hemolysis itself. Understanding hemolysis is crucial for laboratory technicians to ensure accurate test results and maintain patient safety.
