complete blood count (cbc)
A Complete Blood Count (CBC) is a common blood test used to evaluate overall health and detect various conditions. It measures the number and characteristics of red blood cells, white blood cells, and platelets. This test helps diagnose conditions like anemia, infections, and blood disorders, and is often part of routine checkups.
What a CBC measures:
- Red Blood Cells (RBCs): These cells carry oxygen from the lungs to the rest of the body.
- White Blood Cells (WBCs): These cells help the body fight off infections.
- Platelets: These cells help with blood clotting.
- Hemoglobin: The protein in red blood cells that carries oxygen.
- Hematocrit: The percentage of red blood cells in the blood.
Why a CBC is important:
- Diagnosis: A CBC can help diagnose a wide range of conditions, including anemia, infections, and blood disorders.
- Monitoring: It can be used to monitor the effects of treatments, such as radiation or chemotherapy, and to track the progress of certain conditions.
- Screening: A CBC can be part of a routine physical exam and can help screen for abnormalities before they become symptomatic.
