Which test is recommended for diagnosing enterobiasis in a child?

The recommended test for diagnosing enterobiasis, commonly known as pinworm infection, in a child is the scotch tape test. This test is specifically designed to detect the presence of Enterobius vermicularis eggs, which are often laid around the anal area. The method involves placing a piece of clear tape against the skin around the anus, typically in the morning before the child has bathed or gone to the bathroom. The tape is then examined under a microscope for any eggs that may have adhered to it, making it a highly effective method for identifying this particular parasitic infection.

Other tests, like stool cultures and sensitivities or stool for ova and parasites, focus on different types of gastrointestinal pathogens or other parasites and may not be as effective for specifically diagnosing enterobiasis. The Hemoccult test is used to detect hidden blood in stool and does not pertain to parasitic infections like enterobiasis. The scotch tape test's targeted approach for pinworms is why it is the preferred method for diagnosis in this scenario.
