A positive result on the Giardia antigen test indicates the presence of giardiasis, an intestinal infection caused by the Giardia lamblia parasite. This test specifically detects Giardia antigens in stool samples, providing a reliable method for diagnosing giardiasis. Symptoms of giardiasis can include diarrhea, abdominal cramps, bloating, and fatigue, which arise as the parasite disrupts the normal function of the intestine.

Understanding the implications of a positive test is crucial for determining the need for treatment and recommending appropriate measures to prevent further spread of infection. In contrast, the other options are related to different medical conditions that are not assessed by the Giardia antigen test. Therefore, a positive result clearly points to giardiasis rather than conditions such as liver disease, bacterial infections, or hemolytic anemia.
