Phlebotomy
For
Health Care Workers
Phlebotomy
Phlebos is Greek for “Vein”
Tome means to “cut”
Phlebotomy means to cut a vein
Phlebotomy is a term used to describe the specialized technique of blood
collection by a venipuncture
“Veni” is a prefix which means vein
Puncture refers to the penetration of the vein for any
reason, including the administration of IV’s and other
medications. (Venipuncture)
Phlebotomy is an invasive procedure that invades the body
through cutting or puncture, and is performed by
professionals known as a:
Phlebotomists
History of Phlebotomy
First documented in Egypt around 1000 BC
Removing blood from the veins dates back as far as 1400 BC
Leeches: Were used in 1800s
Venesection: Vein was pierced with a sharp object to drain blood
Cupping: Produced a vacuum effect by pulling blood to the
capillaries under a heated glass cup
Phlebotomy profession emerged as a result of technology and
expansion of lab function in the late 1980s and 1900s
Bloodletting as a profession is believed to have originated with
Barber Surgeons in the 12th Century , in Italy.
The Barber Surgeon carried a red and white staff or cane crowned
with a ball as a symbol of his skills in bloodletting and his role in the
health care of the day.
The red stripe of his staff or cane stood for the blood of the patient
The white stripe was for the bandages of the procedure
The ball on the top was for the cup which was used to catch the
blood flow
The Barber Surgeon could perform surgeries, administer enemas, let
blood, pull teeth, and even cut hair.
A blue and white staff signified patriotism
Following developments in the history of
phlebotomy in chronological order
• Hippocrates’ theory on the relationship between excess body fluids
and disease
• Appearance of the barber pole symbol
• Collection of blood for diagnostic testing
• Development of structured phlebotomy training programs
• Certification of phlebotomists
Two behaviors that represent negative body
language:
• Shuffling into the room
• Avoiding eye contact
Demonstrate good telephone communication skills
• By making sure the call is not an emergency before
placing them on hold
• Providing instructions to a patient
• Explain you are going to transfer their call
Why is the appearance and personal hygiene
of the phlebotomists important to the patient?
Patients feel that the quality of care they receive is
reflected by the appearance and cleanliness of the
caregiver
Five barriers to effective verbal communication and
means to overcome each:
• Hearing Impairment: Speak slowly and look directly at the person
• Emotions: Use a calm tone of voice and demonstrate confidence &
concern
• Age: Use age-appropriate phrases and words
• Educational Level: Use terminology appropriate to the educational
level
• Language Proficiency: Attempt to locate a translator; use basic
words and sign language
Clinical and Laboratory Standards Institute (CLSI)
Established the techniques and principals for
the phlebotomy profession.
Primary role of the phlebotomist is: To obtain blood
specimens and transport specimens for diagnostic testing.
Representative of the laboratory to the patient and the
health care staff of the institution. Requires a
professional, courteous, and understanding manner in all
contacts with the patient.
Two methods for collecting blood is:
1. Venipuncture
2. Microtechnique (dermal/capillary puncture)
Sometimes arterial blood is collected by phlebotomists.
Functions of a phlebotomist
1. To obtain venous blood specimens for
diagnostic testing
2. To remove blood from donors for blood
transfusions
3. Collect and properly package urine
specimens
4. Accept incoming specimens
5. Route specimen to the proper
departments to be tested and analyzed
Phlebotomist is a valuable member of the
health care team
Responsible for:
1.Collection
2.Processing
3.Transportation of specimens

Entering the Room
Should greet the patient and identify themselves and the
procedures that will take place. Put the patient at ease.
Effective communication is essential. Both verbal and nonverbal.
Inpatient
Proper identification of the patient is mandatory. Ask for full
name, and check armband. Hospital identification number is the
primary means for identifying the patient.
Outpatient (OPD)
Use the requisition as a reference. Birthday and social security
Number is a source of information about the patient and a
method of communication between the phlebotomist and the
laboratory staff. Today OPD patients also are given an armband.
Post Venipuncture
Thank the patient after the procedure and excuse yourself
courteously, leaving the patient with a positive impression of
you and the laboratory you represent. (Clean up work areas)

Forensic or Chain of Custody Specimens
Forensic specimens, which may be required for law enforcement agencies or
litigation, must follow a special protocol called chain of custody.
Chain of Custody: is a process of in-depth documentation that accounts for every
personnel contact with the specimen from time of collection through
Recording of the final results
Blood Alcohol: Must carefully follow institutional procedure when collecting these
specimens. Use a non alcohol antiseptic or soap and water for cleansing .
Use a vacuum tube with sodium fluoride
Toxicology
Specimens evaluated for the presence of drugs
Therapeutic Drug Monitoring (TDM):
Collection and testing of blood to evaluate and manage medication therapy
effectively and safely
Important to the diagnosis and safe management of drug treatment of the client
Peak Level:
A drug level in the blood collected 15 to 30 minutes after the dosage
has been administered or when the highest serum concentration is expected
Trough Level:
A drug level in the blood collected when the lowest serum concentration
is expected, which is usually immediately before administering the next dosage

Have walls only one cell thick for exchange of
substances between the blood and tissues
