title: Laboratory diagnosis.
abstract: Diagnosis of internal parasitism is based on many factors, including clinical signs, case histories of individual animals and the herds of which they are a part, and, finally, specific laboratory findings. Laboratory methods used can be divided into those associated with the qualitative and quantitative examination of feces for parasite eggs, larvae, and oocysts, and laboratory findings on changes in physiologic status of individuals that may be produced by specific parasites.
