# Complete Blood Count (CBC)

The most common blood test, a Complete Blood Count (CBC), is done to get information on the number of red, white and platelet cells in the blood. It tells your medical team the state of your health.

## Overview

This blood test can be done at any time in a lab, hospital or doctor's office.

A tourniquet or rubber strap is tied around the upper arm to gently keep blood in the vein. Then, a needle with an attached container is inserted into a vein. Often, a large vein in the bend of the elbow or the top of the hand is used. After the container is filled, the needle is removed and a bandage is placed to stop the bleeding.
