Phlebotomy Skills

phlebotomy blood glucose samplePhlebotomy is one of the routine procedures performed by phlebotomy technicians, which often are referred to as phlebotomists. The phlebotomist's daily routine consists primarily of performing venipunctures, or fingersticks to collected capillary, venous, and sometimes, arterial blood samples into blood collection tubes, blood tube labeling, recording, preservation, and transportation of such for laboratory analysis and testing.

Proper blood sample collection is a skillful art. Collecting blood specimens can carry an element of risk for everybody involved, from the laboratory personnel, to the phlebotomist, to the patient. Errors in judgment and technique leaves people vulnerable to injuries and serious consequences.

Adequate education and training of the person responsible for the collection of quality specimens is essential! Otherwise, an improperly collected sample will lead to false lab results and errors that can harm the patient, or even cause their death. Almost certainly it will increase the cost of care. Only through skillful and careful blood drawing procedure can a quality blood sample be obtained.

The right technique will...
prevent errors (e.g. false lab results)
prevent injuries (e.g. anticoagulant reflux, nerve injury)
prevent compromised samples (e.g. hemolysis, hemoconcentration, or agglutination)

The phlebotomist must...
properly identifies the patient
gives proper instructions
properly labels the collection tubes
uses the right blood collection devices and tubes
properly handles the collection tubes
properly secures and accesses the vessel
follows the right order of draw
maintains the sample's integrity while drawing
sufficiently fills the collection tubes
properly processes the blood sample
properly inverts the collection tubes
properly records all information about the sample
and properly stores or transports the tubes to maintain specimen quality.


Other areas of concerns are...
diurnal and circadian variations
patient preparation
patient general health and gender
physiologic variables
medications a patient is taking
patient's position when drawing
touniquet placement and venous stasis
puncture of a secondary site
safety and infection control to prevent complications or injury to self and others.

A phlebotomist must understand that each person is different, each situation is unique, know all possible problem areas and complications, and prevent procedural errors from ever happening. Special challenges arise when collecting blood from the antecubital fossa area is not possible because of the presence of indwelling intravenous lines (IV), or an arterial vessel must be accessed for arterial blood gas tests and there is a vascular access device (VAD) in place.
