Vivek Sinha: The Science Behind a CBC Test
Vivek Sinha, Student at Ganpat University, shared a post on LinkedIn:
“CBC Test: The Story Hidden in Your Blood
Complete Blood Count (CBC) Test
A CBC (Complete Blood Count) is a blood test that measures different components of blood such as red blood cells, white blood cells, hemoglobin, hematocrit, and platelets.
Use: Used to evaluate overall health and detect a wide range of disorders like anemia, infection, and blood diseases.
CBC analyzes cellular components of blood.
- RBC (Red Blood Cells): Carry oxygen
- WBC (White Blood Cells): Fight infection
- Hemoglobin (Hb): Oxygen-carrying protein
- Hematocrit (Hct): percentage of RBC in blood
- Platelets: Help in blood clotting
How is the Test Performed?
Procedure:
- Blood sample collected from vein
- Sample sent to laboratory
- Analyzed using automated hematology analyzer
Preparation:
- Usually no fasting required
- Inform doctor about medications
Role of CBC Test:
A routine diagnostic test for general health check.
Use:
- Detect anemia
- Identify infections
- Diagnose blood disorders
- Monitor treatment (e.g., chemotherapy)
Normal Range (Approx):
Hemoglobin:
- Men: 13–17 g/dL
- Women: 12–15 g/dL
- WBC: 4,000–11,000 cells/µL
- Platelets: 150,000–450,000/µL.”
