The Complete Blood Count (CBC) consists of 20 tests that are an important screening tool for healthcare providers to help diagnose a wide range of disorders, including various infections and leukemia. Although the Complete Blood Count is not a definitive diagnostic test, it gives healthcare providers a starting point to isolate any disorders or diseases that might be present. Red blood cell count, hemoglobin, and hematocrit are three components of a CBC that can help diagnose anemia and other underlying causes. The CBC, when ordered alongside a Wellness Panel, allows healthcare providers to get an accurate assessment of overall patient health. This allows healthcare providers to better recommend effective treatment plans for the patient and a better outcome for overall patient wellness.
