Clear knowlege of common phlebotomy terminology also ensures compliance with healthcare standards and improves patient trust.
Basic Phlebotomy Terms Every Aspiring Professional Should Know
1. Blood Draw / Venipuncture
Blood draw or venipuncture refers to the process of collecting blood from a vein, usually in the arm, for laboratory testing or donation.
2. Phlebotomy
This term describes the entire practice of drawing blood, including patient identification, collection, and sample labeling.
3. Venous Blood
The blood collected from veins; most commonly used in diagnostic testing.
4. Capillary Blood
Blood obtained through skin pricks, typically from fingertips or heels, especially in pediatric or point-of-care testing.
5. Tourniquet
A rubber or fabric band tied around the arm to restrict blood flow and make veins more prominent for easier access.
6. Vein / Blood Vessel
Part of the circulatory system; the target site for venipuncture.
7. Needle Gauge
An indicator of needle size, with lower gauge numbers representing larger needles (e.g., 21G is larger then 23G).selecting the correct gauge is vital for patient comfort and sample quality.
8. Vacuum Collection Tube
A specialized tube that uses vacuum pressure to draw blood automatically during venipuncture.
9. Butterfly Needle / Winged Infusion Set
A small, winged needle used for difficult vein access or pediatric patients.
10. Blood Collection Tubes
Containers for collecting and transporting blood samples, marked with additives necessary for specific tests.
11. Additives in Blood Collection Tubes
- EDTA: Used for hematology tests.
- SST (Serum Separator Tube): Contains gel for serum separation.
- Heparin: For plasma testing.
- Citrate: Used in coagulation studies.
12.Labeling and Specimen Handling
The process of properly labeling blood samples promptly after collection to prevent errors and ensure accurate results.
Advanced and Technical Terminology for Proficient Blood Collection
13. Hemolysis
The destruction of red blood cells, which can compromise sample integrity if blood is mishandled.
14. Tourniquet Time
The duration the tourniquet remains tied-longer times increase the risk of hemoconcentration and hemolysis.
15. Hemoconcentration
Concentration of blood cells and substances caused by prolonged tourniquet application, affecting test accuracy.
16. Aspirating / Drawing Blood
The act of pulling blood into the collection tube using vacuum or syringe.
17. Palpation
Feeling for veins with fingers to locate the best site for blood draw.
18. Access Site
The specific location on the body where blood is drawn,typically a vein in the antecubital fossa.
19. Order of Draw
The correct sequence of blood collection tubes to prevent cross-contamination of additives, such as sterile, microbiology, serum, and plasma tubes.
20. Post-Phlebotomy Care
Steps taken after blood collection to ensure patient comfort,such as applying pressure or a bandage.
