Which of the following statements about hemolysis is true?

Hemolysis refers to the breakdown of red blood cells, leading to the release of hemoglobin and other intracellular components into the plasma or serum. This phenomenon can interfere with laboratory test results, making option C true. When hemolysis occurs, it can cause significant analytical errors, particularly in tests that measure electrolytes, enzymes, and certain proteins. For instance, elevated potassium levels may occur due to the release of potassium from red blood cells, leading to potentially inaccurate assessments and clinical decisions.

Understanding hemolysis is crucial for laboratory professionals, as they must be vigilant in preventing it during blood collection and handling. Factors that can contribute to hemolysis include improper venipuncture techniques, using small needles, or vigorous shaking of samples.

The other options do not accurately reflect the nature of hemolysis. It is not always preventable due to various factors that may contribute to it during specimen collection and processing. Additionally, hemolysis affects samples from all individuals, not just those collected from women. Lastly, hemolysis does not improve the quality of serum samples; in fact, it typically degrades sample quality, complicating the interpretation of laboratory tests.
