Phlebotomy Chapter 8

Also called a butterfly set of scalp needle set, the system can be used for difficult venipunctures due to small or fragile veins. The needle is typically smalled and has thin tuning with a Luer adapter at the end so that it can be used on a syringe or evacuated tube system.

Color-coded specimen collection tube that contains a vacuum so as to aspirate blood when a needle enters a patient's vein.

Used with the evacuated tube method of blood collection, these needles are attached to a holder/adpater and allow for multiple specimen tube fills and changes without blood leakage

Specialized collection devices designed for small quantities of blood

The size (diameter) of the internal bore (opening) of a needle.

Stainless steel beveled needle and tube with attached plastic wings on one end and a Luer fitting attached to the other.

Substance introduced into the blood or specimen to keep it from clotting.

Disposable narrow-bore pipettes that are used for pediatric blood collections and/or microhematorcit measures.

The breakdown or metabolism of glucose by blood cells.

Contains clot activator (serum sample) in plastic or K2EDTA

Used for nutritional studies, therapeutic drug monitoring and toxicology.

Additives include potassium oxalate/sodium fluoride, sodium Na2EDTA or sodium fluoride.

Used primarily for glycolytic inhibition tests (glucose tests)

Glass tubes contain liquid EDTA; plastic tubes have spray-coated EDTA.

Used for whole blood hematology tests. Also used for molecular diagnostic testing, immunology and HgbA1C

Contain lithium heparin and a gel for plasma separation during centrifugation.

Used for assays that require heparinized plasma.

Contain anticoagulants sodium heparin, ammonium heparin & lithium heparin.

Used for plasma or whole blood specimens in chemistry testing.

Contain additive thrombin which makes blood clot in less than five minutes.

Use these tubes for STAT specimens when serum is needed.
