Fecal sedimentation is a diagnostic method effective for detecting giant liver fluke infections, particularly caused by Fasciola hepatica or Fasciola gigantica. This technique involves concentrating eggs from the feces of an infected animal, allowing for the identification of parasitic eggs under a microscope. Since these flukes reside in the liver and gall bladder, their eggs are passed in the host's feces, making this method particularly useful for diagnosis.

Other diagnostic methods listed, such as X-ray imaging, skin scraping, and CT scans, are not appropriate for identifying liver fluke infections. X-rays are generally not effective for visualizing soft tissue such as the liver where these parasites reside. Skin scraping is typically utilized for detecting skin parasites or dermatological conditions, while CT scans, although they provide detailed images of internal structures, are less commonly used specifically for diagnosing fluke infestations due to the presence of eggs in feces. Therefore, fecal sedimentation remains the most applicable method for diagnosing giant liver fluke infections.
