| Abstract | Abstract Objective: To compare the diagnostic efficacy of various stool examination techniques for detection of parasitic infections. Methods: Using a cross-sectional study, a total of 422 achieved fecal samples randomly selected from stool sample blank of DepartmentofParasitology,Phramongkutklao Collegeof Medicine, Bangkok, Thailand, were used for a comparison of stool examination techniques. All stool samples were mixed thoroughly and divided into four portions for examination of parasitic infection using simple smear, formalin-ethyl acetate concentration technique (FECT), Kato technique and fecal parasite concentrator kit. The diagnostic efficacy of each technique was evaluated for the prevalence, sensitivity and negative predictive value. Results: FECT provided the highest sensitivity for parasite infection (80.2%) and Opisthorchis viverrini infection (95.0%) followed by Katotechnique, fecal parasite concentrator kit and direct simple smear technique. The fecal parasite concentrator kit showed the higher sensitivity (30.2%) than the simple smear technique (24.5%). Conclusion: FECT showed the highest diagnostic efficacy among the four methods. Replacement of fecal concentrator kit for FECT and Kato technique is not recommended for detecting parasitic infections. |
