What Does the Full Blood Count (FBC) Measure? (250 words)
The Full Blood Count (FBC) is a crucial diagnostic tool that provides detailed information about the health and composition of your blood. It measures the following key components:
- Red Blood Cells (RBCs):
RBCs transport oxygen throughout your body. Low RBC count or hemoglobin levels may indicate anemia, which can cause fatigue, shortness of breath, and weakness. High RBC counts might suggest dehydration or other health conditions. - White Blood Cells (WBCs):
WBCs are the body's defense against infections. Elevated WBC levels may indicate infection, inflammation, or even certain cancers, while a low count can point to issues with bone marrow, autoimmune diseases, or the effects of certain medications. - Hemoglobin (Hb):
Hemoglobin is the protein in RBCs responsible for carrying oxygen. Low hemoglobin levels are typically seen in anemia, while high levels could suggest lung disease or dehydration. - Hematocrit:
Hematocrit measures the proportion of red blood cells in your blood. Abnormal levels may point to dehydration, anemia, or polycythemia. - Platelets:
Platelets help in blood clotting. Low platelet counts increase the risk of bleeding, while high counts may indicate clotting disorders or inflammation.
This test plays a vital role in diagnosing a wide range of conditions, from anemia and infection to clotting issues and blood cancers. It’s often a first step in investigating symptoms like fatigue, weakness, or unexplained bruising.
Recommended Tests
- Vitamin B12 (Active B12) Test
This test helps diagnose deficiencies that may cause anemia or neurological issues, complementing the FBC results.
Vitamin B12 Test - Iron-binding capacity (TIBC) Test
Measures the blood's ability to bind iron, essential in diagnosing iron-deficiency anemia often indicated by abnormal FBC results.
