Question

Option C is the correct method for transferring blood from a syringe to a vacuum tube. A needless transfer device is specifically designed for this purpose and reduces the risk of accidental needlestick injuries. Option A is not recommended as the needle tip can become dull or damaged by inserting it into the stopper multiple times, which can cause hemolysis of the blood sample. Option B can also cause hemolysis and may introduce air bubbles into the sample. Option D is not a viable option as the lab may require the sample to be in a vacuum tube for proper processing.
