A Complete Blood Count (CBC) is a common blood test that measures various components of your blood, providing valuable information about your overall health. Here's what a CBC typically includes: *Components of a CBC:* 1. *Hemoglobin (Hb)*: Measures the amount of hemoglobin in red blood cells, which carries oxygen. 2. *Hematocrit (Hct)*: Measures the percentage of red blood cells in your blood. 3. *Red Blood Cell Count (RBC)*: Measures the number of red blood cells. 4. *White Blood Cell Count (WBC)*: Measures the number of white blood cells, which fight infections. 5. *Platelet Count*: Measures the number of platelets, which help blood clot. 6. *Mean Corpuscular Volume (MCV)*: Measures the average size of red blood cells. 7. *Mean Corpuscular Hemoglobin (MCH)*: Measures the average amount of hemoglobin in red blood cells. 8. *Mean Corpuscular Hemoglobin Concentration (MCHC)*: Measures the average concentration of hemoglobin in red blood cells. 9. *Red Cell Distribution Width (RDW)*: Measures the variation in red blood cell size. *Purpose of a CBC:* 1. Diagnose and monitor conditions like anemia, leukemia, and lymphoma. 2. Detect infections, inflammation, or bleeding disorders. 3. Monitor the effectiveness of treatments. 4. Screen for blood disorders before surgery or chemotherapy. *Normal Range Values:* (Note: Values may vary slightly depending on the laboratory and individual factors.) - Hemoglobin (Hb): 13.5-17.5 gdL (male), 12-16 gdL (female) - Hematocrit (Hct): 40-54% (male), 36-48% (female) - RBC: 4.32-5.72 millionμL (male), 3.90-5.30 millionμL (female) - WBC: 4, 500-11, 000μL - Platelet Count: 150, 000-450, 000μL - MCV: 80-100 fL - MCH: 27-31 pg - MCHC: 32-36 gdL - RDW: 11.9-14.5% *Abnormal Results:* If your results fall outside the normal range, it may indicate: - Anemia (low RBC, Hb, or Hct) - Infection (high WBC) - Bleeding disorder (low platelet count) - Blood cancer (abnormal WBC or RBC) - Nutritional deficiencies (e.g., iron, vitamin B12) Consult your doctor or healthcare professional to discuss your CBC results and determine the next course of action.
