When using a winged blood collection set,a light blue stopper tube should be collected first.

Question

Quizplus · Accepted Answer

When using a winged blood collection set (butterfly), the light blue stopper tube, which is for coagulation tests and requires a specific blood-to-additive ratio, should not be collected first due to the air in the tubing that can lead to underfilling. A discard tube or another non-additive tube is typically drawn first to ensure proper fill and ratio in the light blue tube.
