A Complete Blood Count (CBC) test is a blood test used to evaluate your overall health and detect a wide range of disorders. By measuring different components of your blood, a CBC test provides critical information about your blood and overall health.
A complete blood count test price in delhi is a common blood test that is often part of a routine checkup. It involves multiple measurements that include the number of blood cells and some of their physical features. The test can tell a lot about a person’s overall health and can help detect a variety of disorders including infections, anemia, diseases of the immune system, and blood cancers.
Components of a CBC Test
Red Blood Cells (RBC)
Red blood cells are responsible for transporting oxygen from your lungs to the rest of your body. The CBC test measures the number of RBCs to help detect conditions such as anemia and polycythemia.
White Blood Cells (WBC)
White blood cells are crucial for fighting infections. The CBC test counts the number of WBCs to help identify infections, inflammation, and immune system disorders.
Hemoglobin
Hemoglobin is the protein in red blood cells that carries oxygen. The level of hemoglobin is a key indicator of anemia and other blood disorders.
Hematocrit
Hematocrit measures the proportion of red blood cells in your blood. This helps diagnose conditions like anemia and dehydration.
Platelets
Platelets are essential for blood clotting. The CBC test evaluates the number of platelets to help detect bleeding disorders and other platelet-related conditions.
Why is the CBC Test Important?
The CBC test is a valuable diagnostic tool for several reasons:
Detecting Anemia
Anemia, characterized by a lack of healthy red blood cells, can be identified through low hemoglobin and hematocrit levels.
Identifying Infections
Elevated white blood cell counts can indicate infections, inflammation, or immune system disorders.
Monitoring Blood Disorders
The CBC test helps monitor conditions like leukemia, which affects white blood cell counts, and thrombocytopenia, which involves low platelet counts.
When Should You Get a CBC Test?
Routine Health Check-ups
A CBC test is often part of regular health check-ups to monitor your overall health.
Symptoms Indicating the Need for a CBC Test
Symptoms such as fatigue, weakness, bruising, or unexplained infections may prompt your doctor to order a CBC test.
Preparing for a CBC Test
Fasting Requirements
Typically, no fasting is required for a CBC test, but always follow your doctor’s instructions.
Medication Considerations
Inform your doctor about any medications or supplements you are taking, as some can affect CBC results.
How is the CBC Test Performed?
Sample Collection
A healthcare professional will draw a small amount of blood from a vein, usually in your arm.
Laboratory Analysis
The blood sample is sent to a laboratory where automated machines analyze the different components.
Understanding Your CBC Test Results
Normal Ranges for Each Component
Normal ranges can vary slightly between laboratories, but typical ranges are:
- RBC: 4.7 to 6.1 million cells per microliter for men, 4.2 to 5.4 million for women
- WBC: 4,500 to 11,000 cells per microliter
- Hemoglobin: 13.8 to 17.2 grams per deciliter for men, 12.1 to 15.1 for women
- Hematocrit: 40.7% to 50.3% for men, 36.1% to 44.3% for women
- Platelets: 150,000 to 450,000 per microliter
Interpreting Abnormal Results
Abnormal results can indicate various conditions, such as:
- Low RBC, hemoglobin, or hematocrit: Anemia
- High RBC: Polycythemia
- High WBC: Infection, inflammation, leukemia
- Low WBC: Bone marrow problems, autoimmune conditions
- Low platelets: Bleeding disorders
- High platelets: Risk of clotting
Common Conditions Detected by CBC Test
Anemia
Low levels of RBCs, hemoglobin, or hematocrit can indicate anemia, causing symptoms like fatigue and weakness.
Leukemia
Abnormal WBC counts can signal leukemia, a type of cancer affecting blood and bone marrow.
Infections
Elevated WBC counts typically indicate infections or inflammatory conditions.
Blood Clotting Disorders
Abnormal platelet counts can lead to conditions that affect blood clotting, such as thrombocytopenia or thrombocythemia.

Follow-Up After Abnormal CBC Results
Additional Tests
If your CBC results are abnormal, your doctor may order further tests, such as a blood smear, bone marrow biopsy, or specific blood tests to identify the underlying cause.
Treatment Options
Treatment will depend on the specific condition diagnosed but may include medications, lifestyle changes, or more intensive therapies like chemotherapy for cancer.
