What is CBC with auto diff blood test?

Answer 1

* The CBC is a series of lab tests that measure the amount, shapes, and sizes of red and white blood cells in a sample. The CBC is routinely ordered during annual physicals and other routine checkups, as it is an inexpensive and easy test to run that provides a lot of information about the patient's health. The CBC is also used to diagnose various illnesses.

The differential count measures the different types of white blood cells and compares their amounts to the total count. It is usually done by a machine (automated differential) but it can be done by a technologist who hand-counts the cells using a microscope (manual differential).
