What is a "blood differential test"?

A blood differential test measures the different types of white blood cells in a blood sample. White blood cells are crucial for the immune system as they help fight infections and other diseases. This test provides a count of the various types of white blood cells, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each type of cell plays a specific role in the immune response. By analyzing the amounts of these cells, doctors can diagnose and monitor conditions such as infections, allergies, and certain blood disorders. The results help in understanding how well the immune system is functioning and in identifying potential health issues.
