What is a complete blood count?
A complete blood count (CBC) is a common blood test used by doctors to screen for a variety of conditions including:
- Bone disorders
- Malnutrition (such as vitamin or mineral deficiencies)
- Autoimmune disorders
- Leukemia and lymphoma
- Sickle cell anemia
A CBC evaluates your overall health by measuring several components of your blood, including:
- Red blood cells
- White blood cells
Abnormalities in these blood levels may indicate the presence of an underlying health condition. In some cases, your provider may adjust any medication you may be taking in light of the results of your CBC.
Unlike other labs and blood tests, CBCs do not require fasting before your appointment.
