Phlebotomy Q&A:

Based on my experience working in phlebotomy practice, hemolysis is indeed one of the most frequent causes of specimen rejection in blood collection procedures. Hemolysis refers to the rupture or destruction of red blood cells, which releases hemoglobin into the plasma and can interfere with lab test results. Preventing hemolysis requires careful technique during venipuncture and handling of blood samples. For example, using appropriate needle size, avoiding excessive suction when drawing blood into tubes, and not shaking tubes vigorously can help maintain red blood cell integrity. It’s also important to avoid drawing blood from hematomas or areas with bruising, as contaminated tissue fluid can increase rejection risk. In addition, high lipid content in blood samples can sometimes cause issues, though it’s less common than hemolysis for specimen rejection. For students preparing for phlebotomy exams or those practicing phlebotomy, understanding these common errors and how to avoid them is crucial. It improves not only your technical skills but also patient experience by reducing the need for redraws and delays in diagnostics. Always remember to follow your facility’s protocols closely and communicate with lab personnel if you suspect hemolysis or sample quality problems. Proper training and ongoing practice sharpen your ability to collect clean, usable specimens every time.
