Question

Quizplus · Accepted Answer

A green tube top is used for collecting plasma specimens that are needed for chemistry testing, including amino acid screens. The green top tube contains the anticoagulant heparin and a gel separator that separates the plasma from the blood cells. This allows for easy and accurate testing of the plasma without interference from the cells. The other tube tops listed (lavender, red, gray) are not typically used for amino acid testing.
