You're collecting blood for a STAT glucose test. Which of the following tubes is the most appropriate choice?
A
a tube with a gray stopper
B
a tube with a red stopper
C
an SST tube
D
an STAT tube
Blood cells continue to metabolize even after they're removed from the body. As part of this process, glucose gets broken down. Gray-stoppered tubes contain anticoagulants that act as glycolytic inhibitors, reducing the amount of glucose that gets broken down post draw which results in a more accurate STAT glucose test.
