Parasites Identification: Direct Smear Examination

. The direct wet smear examination of stool is a crucial diagnostic method to rapidly detect the presence of intestinal parasites, including motile trophozoites, cysts, eggs, or larvae, in fresh stool samples.
. It is particularly useful for identifying active parasitic infections, assessing gastrointestinal symptoms such as diarrhea, and guiding prompt treatment decisions.
