A complete blood count (CBC) with automated differential is a common laboratory test that provides a comprehensive evaluation of the cellular components of blood. This test analyzes red blood cells, white blood cells, and platelets. The “automated differential” portion uses technology to identify and count the different types of white blood cells (neutrophils, lymphocytes, monocytes, eosinophils, and basophils) present in a sample. For instance, an elevated neutrophil count might indicate a bacterial infection, while an increase in lymphocytes could suggest a viral infection.
The availability of a complete blood count with an automated differential offers significant benefits in medical diagnosis and monitoring. The test aids in the early detection and assessment of a wide range of conditions, including infections, anemia, and leukemia. Historically, performing a manual differential was a time-consuming process requiring skilled technicians to visually count cells under a microscope. Automated systems provide faster turnaround times, reduce inter-operator variability, and increase the precision of cell counts, enhancing the efficiency of healthcare delivery.
