Blood collection (Venepuncture)

General information

Venepuncture (Blood Collection)

Venepuncture is a quick and routine procedure used to collect a blood sample from a vein, most commonly from the arm. The procedure is performed by trained medical professionals and provides the necessary material for laboratory testing.

What the procedure involves

• The patient is comfortably seated and the arm is positioned for support.

• The skin is cleaned with a disinfectant.

• A sterile needle is inserted into a vein, and the required amount of blood is collected.

• After the needle is removed, gentle pressure is applied to the site to prevent bruising.

The entire process takes only a few minutes and is generally well tolerated.

Why venepuncture is performed

Blood samples are used for a wide range of laboratory tests, including:

• complete blood count

• biochemical analysis

• hormone testing

• immunological and serological tests

• coagulation studies

Patient preparation

Some tests may require:

• fasting for 8–12 hours

• avoiding heavy meals or alcohol the day before

• drinking water to ensure easier vein access

Specific instructions may vary depending on the test.
