What error might cause hemolysis in a blood specimen?

• A. Transporting the tubes horizontally
• B. Using a dull needle for collection
• C. Filling the tube too quickly
• D. Allowing the specimen to freeze

Answer: (A)

The correct answer pertains to the potential for hemolysis caused by the manner in which blood specimens are transported. Transporting blood tubes horizontally can lead to agitation of the blood within the tubes. When blood components are disturbed, especially red blood cells, they can rupture, leading to hemolysis. This is a crucial consideration for maintaining specimen integrity, as hemolyzed samples can compromise test results, making them unreliable for clinical decision-making. While using a dull needle might cause issues during venipuncture, such as pain or difficulty in obtaining an adequate sample, it does not directly lead to hemolysis as transporting the tubes might. Filling the tube too quickly could introduce air bubbles or cause other collection issues but is less likely to result in hemolysis compared to improper transportation. Allowing a specimen to freeze can adversely affect the stability of certain analytes but is not a direct cause of hemolysis. Each option presents a different risk, but the manner of transport specifically relates to the potential for disrupting the red blood cells in the specimen.
