When a venipuncture is performed using a lavender top vacutainer tube, the sample?

Should be immediately centrifuged
Requires no special handling
Contains a clot activator
Both a and c

The correct answer is: Both a and c

When a venipuncture is performed using a lavender top vacutainer tube, the sample should be immediately centrifuged because the tube contains an additive that helps prevent blood from clotting. This is important for accurate testing because clotting can alter the composition of the blood sample. B is incorrect because all blood samples require proper handling to maintain integrity. Additionally, lavender top vacutainer tubes do not contain a clot activator as stated in option C, but rather an anticoagulant. Therefore, D is the most accurate answer as it combines the correct handling method and mentions the type of additive present in the tube.
