The CBC with Differential (CBC w/ Diff) Panel is a comprehensive blood test that evaluates different components of blood. It includes a complete blood count (CBC) along with a differential white blood cell count. This panel assesses red and white blood cell counts, hemoglobin, platelets, and various white blood cell types, providing a detailed analysis of overall blood health. The CBC w/ Diff is crucial for diagnosing and monitoring various conditions, such as infections, anemia, and immune system disorders.
