What is the Complete Blood Count (CBC)?
The Complete Blood Count (CBC) is also known as Full Blood Count (FBC) or Full Hemogram (FHG). It’s a fundamental blood test that evaluates the three main types of cells in your blood: red blood cells, white blood cells, and platelets. It is one of the most common and informative diagnostic tools used to assess general health status and screen for a wide range of disorders.
Why is the CBC/FHG Test Performed?
Your doctor may order a CBC as part of a routine check-up or if you are experiencing:
- Unexplained fatigue or weakness (potential anemia).
- Frequent bruising or bleeding (potential platelet issues).
- Persistent fever or signs of infection (white blood cell response).
- Chronic inflammation or suspected bone marrow disorders.
What does a complete blood count evaluate?
A CBC analyzes several components of your blood:
- Red Blood Cell (RBC) Count: Cells that carry oxygen throughout your body.
- Hemoglobin (Hb): The protein in RBCs that holds oxygen.
- Hematocrit (Hct): The proportion of red blood cells to the fluid component (plasma).
- White Blood Cell (WBC) Count: Your body’s primary defense against infection.
- Platelet Count: Small cells that help your blood clot.
- Mean Corpuscular Volume (MCV): The average size of your red blood cells.
What is the Clinical Significance & Interpretation of the CBC test?
Doctors use your CBC results to access vaoius dieases and health conditions such as:-
- High RBC/Hemoglobin: May suggest dehydration, smoking, or certain lung/heart diseases.
- High WBC: Typically indicates an active infection, inflammation, or an immune system disorder.
- High Platelets: Can be caused by inflammation or bone marrow disorders.
What do low levels indicate?
- Low RBC/Hemoglobin/Hematocrit: This is the primary indicator of Anemia, which can be caused by iron deficiency, vitamin B12 deficiency, or blood loss.
- Low WBC: May indicate a bone marrow problem, an autoimmune condition, or a side effect of certain medications.
- Low Platelets: Increases the risk of excessive bleeding or bruising.
Understanding Your Results
Results are presented as numerical values alongside a “reference range.” If your values fall outside these ranges, it does not always indicate a disease, but it does warrant a discussion with a physician.
| Component | Typical Adult Range (Approx.) |
| Hemoglobin (Male) | 13.5–17.5 g/dL |
| Hemoglobin (Female) | 12.0–15.5 g/dL |
| White Blood Cells | 4,500–11,000 cells/mcL |
| Platelets | 150,000–450,000/mcL |
