Giardia antigen test

The Giardia antigen test is a medical test that detects a specific protein from the Giardia parasite in a person's stool sample. Giardia is a microscopic organism that can cause gastrointestinal symptoms like diarrhea, stomach cramps, and nausea. When a person is infected, the parasite releases these proteins into the intestines, which can then be identified through the test. This helps doctors determine if Giardia is the cause of the symptoms, allowing for accurate diagnosis and appropriate treatment. The test is quick, reliable, and non-invasive, making it a useful tool for diagnosing giardiasis.
