In simple words: This is a lab test that gives detailed information about the cells in your blood, like the red blood cells that carry oxygen, the white blood cells that fight infection, and the different types of white cells. It helps doctors check for things like anemia, infection, or other blood disorders.

This code represents a comprehensive automated blood analysis that includes measuring hemoglobin, hematocrit, red blood cell count, white blood cell count, and an automated white blood cell differential count. It does not include a platelet count.

Example 1: A patient presents with fatigue and shortness of breath. A CBC with differential is ordered to assess for anemia or other blood disorders., A patient has a suspected infection. A CBC with differential is ordered to check for an elevated white blood cell count and assess the types of white blood cells present., A patient is undergoing chemotherapy. Regular CBCs with differential are ordered to monitor their blood cell counts and detect any potential complications.

The documentation should include the reason for the test, the patient's signs and symptoms, and any relevant medical history.
