GRAY 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.

Determining the Accuracy of Your Glucose Meter For example, if your glucose meter result was 100 mg/dL, it could vary on the downside to 80 mg/dL or on the up side to 120 mg/dL and still be considered clinically accurate. All blood glucose meters use whole blood to measure glucose. Whole blood is simply a blood sample that contains the red blood cells.

Glucose meter It is a key element of home blood glucose monitoring (HBGM) by people with diabetes mellitus or hypoglycemia. A small drop of blood, obtained by pricking the skin with a lancet, is placed on a disposable test strip that the meter reads and uses to calculate the blood glucose level. The meter then displays the level in units of mg/dl or mmol/l.
