Which method is not primarily used to detect endoparasites?

• A. Fecal examination
• B. Serology
• C. Skin scraping
• D. Biopsy

Answer: (C)

Detecting endoparasites relies on samples from inside the body. Fecal examination is used to find intestinal parasites by identifying eggs, cysts, or larvae shed in stool. Serology detects antibodies or antigens indicating infection, useful for certain systemic or tissue-dwelling parasites. Biopsy allows direct examination of tissues to locate parasites within organs. Skin scraping, by contrast, targets parasites on or just beneath the skin, such as mites and other ectoparasites, and is not primarily used to detect endoparasites.
