True. The Kato-Katz technique is a World Health Organization (WHO)-recommended method for the qualitative and, more importantly, quantitative diagnosis of soil-transmitted helminth (STH) infections. It involves preparing a thick smear of stool on a microscope slide, clearing it with glycerol-soaked cellophane to make the eggs visible, and then systematically counting the eggs under a microscope. The egg count per gram of feces can be estimated, which provides information on the intensity of infection—a critical parameter for public health decisions and monitoring control programs. While it is excellent for detecting and quantifying helminth eggs (e.g., Ascaris, Trichuris, hookworm), it is not suitable for diagnosing protozoan infections. Protozoan cysts and trophozoites are often distorted or destroyed by the glycerol clearing process and are not reliably detected with this method.
