Testing of a fecal stool for parasites is primarily performed in which laboratory department?

1. Hematology

2. Microbiology

3. Immunology

4. Urinalysis

The correct answer is: Microbiology

Testing of fecal stool for parasites is primarily performed in the microbiology department. This department specializes in the study of microorganisms, including bacteria, viruses, fungi, and parasites. When fecal samples are analyzed for parasites, various techniques such as microscopy and culture may be utilized to detect the presence of parasitic organisms like Giardia, Entamoeba histolytica, or various helminths. Microbiology labs play a crucial role in identifying these pathogens which can cause gastrointestinal infections. The identification process often involves examining stool samples for eggs, larvae, or cysts of parasites, along with performing additional tests that may help confirm the presence of specific parasites based on their biological characteristics. Other laboratory departments focus on different areas of testing. Hematology deals with blood cell disorders and overall blood composition, immunology focuses on immune system function and responses, while urinalysis examines urine samples for various metabolic and systemic disorders. Each department has its specific scope, which highlights the specialized function of microbiology in the context of fecal analysis for parasitic infections.
