Full Blood Count (FBC) Blood Test: A Comprehensive Guide

What is an FBC Blood Test?

A Full Blood Count (FBC), also known as Complete Blood Count (CBC), is one of the most commonly performed blood tests. It provides important information about the different types of blood cells in your body, including red blood cells, white blood cells, and platelets.

What Does an FBC Test Measure?

The test analyzes several components:

Red Blood Cells (RBCs)

• Hemoglobin levels

• Hematocrit (percentage of blood volume occupied by RBCs)

• Mean corpuscular volume (MCV)

• Red cell distribution width (RDW)

White Blood Cells (WBCs)

• Total white cell count
• Different types of white blood cells:

Neutrophils

Lymphocytes

Monocytes

Eosinophils

Basophils

Platelets

• Platelet count
• Mean platelet volume (MPV)

Why is an FBC Test Performed?

An FBC may be ordered to:

• Evaluate overall health

• Screen for various disorders

• Diagnose conditions like anemia

• Monitor existing blood conditions

• Check for infections

• Monitor treatment effects
