Study Notes

Order of Draw and Tube Characteristics

The Order of Draw is a standardized procedure to minimize cross-contamination of additives and prevent sample hemolysis.
Blood Culture collections are associated with yellow tube stoppers.
Tubes with Light Green stoppers contain Heparin as an additive.
Coagulation tubes are associated with blue tube stoppers.
PSTs stand for Plasma Separator Tubes.
Plasma-preparation tubes (PPTs) are associated with lavender tube stoppers.

Blood Collection Systems

The Evacuated Tube System (ETS) is considered the most efficient for collecting blood samples.
The syringe system has a resheathing feature in its needle component.

Tube Preparation and Additives

Evacuated tubes are filled with a vacuum to prevent exposure of the specimen to contaminants.
Additives in ETS tubes are primarily used for anticoagulation, clotting, and separation of blood components.
"Nutrient" is NOT a category of additives used in blood collection.
Color coding is used to identify additives in blood collection tubes, ensuring correct tube selection for each test.

Infection Control and Vein Location

Antiseptics and disinfectants are used during venipuncture to prevent the spread of infection.
Phlebotomy needles used in evacuated tube systems or syringe systems include winged needles.
A vein-locating device is used in venipuncture to facilitate vein visualization and minimize errors.
Gloves and glove liners are worn during venipuncture to prevent exposure to infectious materials.
Iodine is NOT used as an antiseptic in venipuncture procedures.
The function of an Evacuated Tube System (ETS) is to facilitate the safe and efficient collection of blood samples.
