Sodium fluoride is found in which tube color?

Sodium fluoride is used as a glycolysis inhibitor in blood collection tubes for glucose testing. It’s included in the gray top tube, which also contains potassium oxalate as an anticoagulant. Fluoride blocks glycolysis, preventing glucose from being consumed by cells after draw, so the measured glucose more accurately reflects the patient’s true level at collection. Other common tube colors don’t contain sodium fluoride, as they’re used for different tests or purposes (for example, red top for serum without anticoagulant, blue for citrate, green for heparin, and purple for EDTA).
