Overview

A CBC is a blood test that checks the levels of different cells in your blood. It gives doctors a general picture of your health and can help detect issues like low iron (anemia), infections, and immune system problems.

Candidates for CBC

You may need this test if you:

  • Have symptoms like tiredness, fever, or weakness
  • Are being checked for anemia or infection
  • Have a condition that affects the blood or immune system
  • Are preparing for surgery or other medical procedures
  • Need routine bloodwork as part of your care

Preparation for CBC

You don’t need to fast or follow any special instructions. Just show up for your appointment as directed.

Risks for CBC

CBCs are very safe. The most common side effect is a little soreness or bruising where the blood was drawn.

Recovery from CBC

There’s no downtime after the test. You can return to work, school, or your regular schedule right away.
