What is phlebotomy?

Phlebotomy is the process of drawing blood from a patient for medical testing, transfusions, donations, or research. A trained healthcare professional called a phlebotomist typically performs this procedure by inserting a needle into a vein to collect a blood sample. The blood sample is then sent to a laboratory for analysis.

Phlebotomy is a procedure in which blood is drawn from a vein for various medical purposes, such as:

- Diagnostic tests: Blood is analyzed for various substances (e.g., glucose, electrolytes, lipids, hormones) to detect and diagnose medical conditions.
- Monitoring: Blood is drawn regularly to monitor ongoing medical conditions or the effects of treatments.
- Blood donations: Blood is collected for transfusion or other uses.
- Therapeutic phlebotomy: Excess red blood cells are removed in certain conditions (e.g., hemochromatosis).

Phlebotomy typically involves the following steps:

1. The phlebotomist identifies the patient and the required tests.
2. The phlebotomist selects a suitable vein, usually in the arm or hand.
3. The vein is cleaned and a needle is inserted.
4. Blood is drawn into a syringe or collection tube.
5. The puncture site is bandaged.

Phlebotomy is a routine procedure that is generally safe and well-tolerated. However, it can occasionally cause minor discomfort, bruising, or infection at the puncture site.
