The unreliability of the routine fecal examination for parasitic ova and cysts

The unreliability of the routine fecal examination for parasitic ova and cysts and the reliability of concentration technics are proven. Facts and figures from researches done abroad and locally are presented which prove beyond any doubt the inefficiency of the commonly used routine fecal examinationIt is also shown that the examination of multiple specimens, especially with the aid of concentration technics, greatly increases the chances of getting a positive resultIt is therefore suggested that the routine fecal examination except for rare indications stated in the paper, should no longer be depended upon for specific laboratory diagnosis of intestinal parasitic infections.
