GRAY

ADDITIVES

Potassium Oxalate and Sodium Fluoride
Sodium fluoride/Na2 EDTA
Sodium Fluoride (no anticoagulant, will result in serum sample)

ACTION

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. The resulting supernatant fluid is PLASMA. Sodium fluoride is an anti-glycolytic only, resulting fluid is SERUM.

The tube must be inverted 4-5 times after collection to allow adequate mixing of the blood with the additive. Failure to mix may result in the sample clotting. Clotted tubes will be rejected.

DEPARTMENT

Clinical Chemistry -The clinical chemistry laboratory performs a wide variety of analytic procedures, both specialized and routine. These include tests for the evaluation of endocrine and metabolic disorders, therapeutic drug monitoring and toxicology, protein electrophoresis, lipid panels, as well as those tests commonly called routine such as hepatic function tests, electrolytes and markers of cardiac damage.

TESTS PERFORMED

Glucose Levels
Blood Alcohol Levels

Lactate
Bicarbonate
