Test Description
The Giardia Lamblia Antigen, Stool test is a diagnostic examination that checks for the presence of the Giardia lamblia parasite in the stool. This parasite is a common cause of diarrhea and is found in the gastrointestinal system, being excreted in the stool. The test specifically looks for the Giardia antigen, which is a sensitive screening method for the detection of Giardia antigens present in fecal specimens[4].
Indications of the Test
The test is typically ordered to diagnose giardiasis, an infection of the small bowel caused by the Giardia lamblia parasite. Symptoms of giardiasis include watery diarrhea, foul-smelling, fatty stools, bloating, excessive gas, nausea, vomiting, abdominal cramps, dehydration, and weakness. The test may also be recommended for individuals with unexplained diarrhea or those who have been exposed to contaminated water, food, or have a history of travel to different countries[2][3].
Patient Preparation/Instructions
No special preparation is usually required for this test. Patients may be asked to provide a stool sample, and they will be given instructions on how to collect the sample. It’s important to follow the instructions provided by the healthcare provider or the lab to ensure an accurate test result[2][3].
Typical Reference Values
The test results may vary depending on the laboratory used. If the Giardia antigen is detected in the stool sample, it is indicative of giardiasis. However, due to the parasite’s life cycle, more than one sample may be needed for an accurate diagnosis[2].
Turnaround Time
The typical turnaround time for this test is 1 to 3 days[4].
