Serology testing allows the determination of immunity against different infecting organisms via the dosage of IgG. When the direct detection of a pathogen is not possible, detection of specific IgM antibodies or antigens may also help to diagnose an acute infection.
What is the importance of serologic diagnosis of protozoan infections?
