Cryptosporidium Antigen, Feces
Use
The test is crucial for establishing the diagnosis of intestinal cryptosporidiosis, which is an infection of the intestinal tract caused by Cryptosporidium parasites. These parasites are often spread through contaminated water, making the test especially useful in outbreak scenarios. It offers a sensitive and specific detection method for cryptosporidiosis, especially compared to the fecal ova and parasite examination which is less effective.
Special Instructions
For manual orders, complete and send one of the following forms with the specimen: Gastroenterology and Hepatology Test Request or Microbiology Test Request. Testing is performed Monday through Friday, and reports are provided 1 to 3 days after sample receipt.
Limitations
The test may require the examination of at least two fecal specimens to detect Cryptosporidium using antigen testing. False positives may occur if feces contain large amounts of red or white blood cells. Additionally, improper specimen collection or handling could lead to inaccurate results. The antigen test is more specific compared to traditional fecal ova and parasite examinations.
