Graphical representation of the study design. The study was divided into two parts: A and B. In Part A of the study, 200 fresh stool samples were analyzed using the Orienter Model FA280 automatic digital feces analyzer. Species identification was evaluated by a skilled medical technologist through user audits, and the results were reported by the analyzer’s artificial intelligence program. In Part B of the study, 800 preserved stool samples were subjected to parasite detection using both the FA280 feces analyzer (with user audit) and the formalin-ethyl acetate concentration technique (FECT). All preserved stool samples were analyzed once with each method
