-Arm on side of mastectomy
-Edematous areas
-Hematoma
-Arm in which blood is being transfused
- Scarred areas
-Arms w/ fistula or vascular grafts
- Sites above IV cannula
6The most preferred because blood is collected directly from the vein in the tube, minimizing the risk of specimen contamination and exposure to the blood
Evacuated Tube System (ETS)
7What are the 3 basic components of ETS?
1. Multi-sample needle
2. Tube holder
3. Evacuated tubes
8used on small, fragile and damaged veins
needle and syringe method
9can be used with the ETS and syringe used to draw blood from infants and children, hand veins and other difficult to draw situations
Winged Infusion Set (Butterfly)
10It is a special sequence of tube collection that reduces the risk of cross contamination by the tube additives that could lead to erroneous results
Order of draw
11Correct Order of draw
1. Yellow (SPS)
2. Light blue (citrate)
3. Plain red (additive)
4. Plastic red (clot activator)
5. Gold (SST/Gel w/ Clot Activator)
6. Green
7. Lavander/Pink

18an alternative collection procedure when minute amounts of blood are needed for testing, or for patients for whom venipuncture is inadvisable or impossible.

1. Blood smear
2. Lavender- EDTA microtainers
3. Green- Lithium Heparin
4. Mint green- Lithium Heparin PST
