Differential Staining is a staining process which uses more than one chemical stain. Using multiple stains can better differentiate between different microorganisms or structures/cellular components of a single organism.
The differential is often performed as part of the complete blood count (CBC) , which may be ordered at the time of a routine health exam. A differential may be included as part of the CBC when someone has general signs and symptoms of an infection and/or inflammation, such as: 1  Fever, chills. 2  Body aches, pain. 3  Headache.
