A CBC test, or Complete Blood Count, is a common blood test that helps monitor your overall health. It measures red and white blood cells, hemoglobin, hematocrit, and platelets. How often you should get it depends on your age, health condition, and risk factors. For generally healthy adults, an annual CBC test is usually sufficient. People with chronic illnesses or ongoing treatments may need it more frequently. Your doctor may also recommend a CBC test before surgery or during routine checkups. Regular testing can help detect infections, anemia, and other blood-related conditions early. Staying on top of CBC tests ensures better health management and timely medical intervention.
