The Complete Blood Count with Differential (CBC w/ Diff) is the most commonly ordered blood test. It counts your red blood cells, white blood cells, and platelets, and provides a detailed breakdown of the five types of white blood cells. This helps detect infections, anemia, clotting disorders, immune system conditions, and blood cancers.
Complete Blood Count with Differential evaluates red cells, white cells, and platelets — screening for anemia, infection, and clotting issues.
Anyone doing an annual checkup, investigating fatigue, frequent infections, easy bruising, or unexplained bleeding. Standard in any pre-op workup and monitoring TRT or chemotherapy.
