when drawing blood which tube is used for glucose
Sterile blood collection tubes for laboratory procedures requiring plasma or whole blood chemistry procedures where glycolytic inhibition of specimen is required. The anti-glycolytic properties prevent the blood cells from using the glucose in the sample. Used instead of red top when there will be a delay in getting blood to the lab for a glucose level. Oxalate and EDTA are anticoagulants which will prevents the blood from clotting, sodium fluoride is a stabilizer.
