Complete Blood Count (CBC)

Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. RBCs are the abundant cells in the blood that consist of a protein called hemoglobin, which helps transport oxygen throughout the body. WBCs form part of the immune system that helps protect the body against infections and other diseases. Platelets are tiny blood cells that help form clots to stop bleeding after an injury. As these blood cell types perform vital functions, determining their levels helps provide important health information.

Any imbalance in these cells, either too few or too many cells, can indicate underlying health concerns. A CBC test helps in the early detection of these changes even before symptoms appear.

Some of the common conditions that can be identified or monitored with the help of a CBC test include:

• Anemia: Deficiency of RBC or low hemoglobin levels may lead to anemia.
• Infections: Elevated levels of WBC can be a sign of underlying infection or inflammation.
• Bleeding or Clotting: Abnormal platelet count can lead to easy bruising or prolonged bleeding.
• Immune Disorders and Cancers: Certain changes in blood cell counts and abnormal blood cell appearance may indicate some serious conditions like leukemia or autoimmune diseases.

No special preparation is needed for a CBC test. Eat and drink as per the normal routine. However, inform the doctor about all the current medications or any underlying health conditions to ensure accurate interpretation of the test results.

Test result ranges are approximate and may differ slightly between labs. Talk to the doctor about your specific test results. The results will help them determine your medical condition and formulate an overall treatment plan. They may suggest lifestyle recommendations and medications if required to manage your condition.
