Phlebotomy
Gray top tubes

Contain an inhibitor of glycolysis, such as sodium fluoride.May also contain an anticoagulant such as potassium oxalate. Used for accurate determination of glucose levels.

Collection tubes

Blood may be collected into either:Red top (clot) tubes.Speckle top tubes (serum separator tube).Gray top tubes specifically designed to preserve glucose levels. Gray top tubes contain additives such as sodium fluoride or potassium oxalate, which prevent metabolism of glucose by blood cells.

Normal Crystals

Normal crystals include uric acid, calcium oxalate, amorphous urates or phosphates, triple phosphate, ammonium biurate and calcium carbonate.

Crystals in Normal Acid Urine

Crystals found in normal acid urine include uric acid, calcium oxalate and amorphous urates. This slide shows an example of uric acid crystals.

Crystals in Normal Alkaline Urine

Crystals found in normal alkaline urine include triple phosphate, ammonium biurate, calcium carbonate, amorphous phosphates, and calcium oxalate. This slide shows an example of triple phosphate crystals. These may appear as four to six sided prisms resembling coffin lids. They indicate either stasis of the bladder or a stale sample.

Calcium Oxalate Crystals

Calcium oxalate crystals have a characteristic octahedral or envelope shape. Fine focusing will cause the "x" to be refractile. Size may vary from extremely small to quite large. They are associated with diets high in oxalic acid or chemical toxicity. Occasionally calcium oxalate crystals are dumbbell or oval in shape.
