Antigen detection, antibody test (elisa) and polymerase chain reaction (pcr) •• endoscopy with scrapings or biopsy and stained slides (iron hematoxylin or trichrome) may provide more definitive diagnosis of amebiasis •• diagnosis for liver abscess includes serology and liver scans (using isotopes by ultrasound or computed tomography [ct]) or mri. However, none of these are specific for liver abcess. In rare instances, needle aspiration of hepatic abscess may be attempted using ultrasound guidance pharmacologic therapy metronidazole (flagyl), dehydroemetine, and chloroquine (aralen) are tissue-acting agents, and iodoquinol (yodoxin), diloxanide furoate (furamide), and paromomycin (humatin) are well absorbed that the amounts of the drug remaining in the bowel may be insufficient to have luminal or local effects.
