How is the differential count affected parasitic infections?

In parasitic infections, the differential white blood cell count often shows an increase in eosinophils, a type of white blood cell that plays a crucial role in the body's immune response to parasites. This eosinophilia is typically a response to helminths (worms) and certain protozoan infections. Additionally, there may be changes in other cell types, such as lymphocytes, depending on the specific parasite and the stage of the infection. Overall, a differential count can provide valuable insights into the presence and type of parasitic infection.
