Decontamination of hands as a substitute for hand washing provided that the hands are not visibly soiled.
Hand Sanitizers
Why are the ethylenediaminetetraacetic acid (EDTA) tubes drawn second to the last?
These tubes are drawn near the end of the order as EDTA binds many metals, in addition to calcium, thus, causing complications in other tests.
It is responsible for more carryover problems than any other additive as it could falsely elevates sodium and potassium levels, chelates and decreases calcium and iron levels, and elevates PT and PTT results.
Why is a winged infusion set more recommended to be used for collecting blood from small or difficult veins such as hand veins and veins of elderly and pediatric patients?
It allows much more flexibility and precision than a needle and syringe.
A device that is applied or tied around a patient’s arm prior to venipuncture to restrict blood flow.

The number of inversions of Clot Activator Additives.

Enumerate the Order of Draw in chronological order.
❖ Sterile Tube (Blood Culture)
❖ Blue-Top Coagulation Tube
❖ Serum Tube with or without Clot Activator, with or without Gel
❖ Heparin Tube with or without Gel Plasma Separator
❖ EDTA Tube
❖ Glycolytic Inhibitor Tube
Is any substance placed within a tube other than the tube stopper.
Blood Additives
It can occur from improper storage, opening the tube, dropping the tube, advancing the tube too far onto the needle before venipuncture, or if the needle bevel becomes partially out of the skin during venipuncture.
Premature Loss of Vacuum
How can carryover/cross contamination commence?
It can commence when blood in an additive tube touches the needle during ETS blood collection, or
When blood is transferred from a syringe into ETS tubes.
