The formalin-ether concentration technique (FECT) is a widely used sedimentation technique for the diagnosis of intestinal protozoa in preserved stool samples . The most commonly used fixatives for stool preservation are either formalin or sodium acetate-acetic acid-formalin (SAF) (3, 24, 40). Of note, the FECT has some drawbacks.

Comparison of a Urine Antigen Assay and Multiple …

ABSTRACT. Detection of worm antigen in urine is a sensitive diagnostic method for opisthorchiasis, particularly for light-intensity infections; however, the presence of eggs in feces is essential for validating results from the antigen assay. To address the issue of low sensitivity of fecal examination, we modified the protocol for the formalin-ethyl acetate …

Macroscopic and Microscopic Examination of Fecal Specimens

This chapter discusses about macroscopic examination and microscopic examination of fecal specimens. The microscopic examination of the stool specimen, normally called the ova and parasite examination, consists of three separate techniques: the direct wet smear, the concentration (sedimentation and flotation), and the permanent …
