When transferring blood from a syringe to evacuated tubes, what device is recommended for best practice?

  1. Needle guard

  2. Syringe holder

  3. Blood transfer device

  4. Vacuum seal

The correct answer is: Blood transfer device

Using a blood transfer device is recommended for transferring blood from a syringe to evacuated tubes for several important reasons. This specialized device is designed specifically to facilitate the safe and efficient transfer of blood, minimizing the risk of contamination and preventing hemolysis of the blood specimen. Blood transfer devices typically allow for a controlled flow, which helps to fill the evacuated tubes without creating excessive turbulence that could affect the integrity of the sample. They often have features to ensure a secure connection to both the syringe and the tube, further reducing the risk of spills and ensuring that the blood is transferred directly and efficiently. Additionally, the use of a transfer device helps to minimize the risk of needlestick injuries, promoting safer handling practices. Other options, such as a needle guard or vacuum seal, do not provide the same specific functionality and protection for this particular procedure, while a syringe holder is generally used to stabilize the syringe but doesn't assist with the transfer itself.
