A full blood count (FBC) is a common blood test that provides valuable information about your overall health by analyzing red and white blood cell counts. Here’s what these counts can reveal:
- Red Blood Cells (RBCs)
- What They Do: RBCs transport oxygen from your lungs to the rest of your body. Adequate oxygen delivery is vital for energy and normal organ function.
- Low RBC Count (Anemia): Can be caused by iron deficiency, vitamin B12 deficiency, or chronic disease. Symptoms include fatigue, weakness, and shortness of breath.
- High RBC Count (Polycythemia): May result from dehydration, lung disease, or living at high altitudes. It can increase the risk of clotting and heart problems.
- White Blood Cells (WBCs)
- What They Do: WBCs are essential for the immune system, fighting infections and responding to inflammation.
- High WBC Count (Leukocytosis): Often indicates infection, inflammation, or, in some cases, blood disorders such as leukemia. It can also be a response to stress or physical exertion.
- Low WBC Count (Leukopenia): May signal immune suppression, bone marrow issues, or chronic illnesses like HIV or autoimmune diseases.
An abnormal result in either RBC or WBC counts typically requires further investigation to identify underlying causes, whether they be infections, nutritional deficiencies, or more severe conditions like cancer or bone marrow disorders.
Recommended Tests
- Ferritin Test
A ferritin test measures your body’s iron stores, often used in conjunction with an FBC to investigate the cause of anemia.
Ferritin Test - Complete Blood Count (CBC)
The CBC test is the full panel for evaluating red and white blood cells, as well as hemoglobin, hematocrit, and platelets.
