Giardia Antigen Test - More Information

The giardia test, sometimes known as a giardia ag test, checks for the presence of giardia antigen in the stool.

Giardia is a parasitic protozoan that causes gastrointestinal infections after one ingests contaminated water or food. Once giardia settles into the intestines, symptoms typically start within two days. Giardia wreaks havoc on the GI system, causing smelly and violent diarrhea and cramping with nausea at times. Untreated, symptoms can last for up to six weeks and can cause excessive water loss without active rehydration. Longer term, a giardia infection can lead to giardiasis, a disease that results in malabsorption from damage to the intestinal tract.

This giardia antigen test analyzes the stool for the presence of antigens specific to giardia. This stool test requires at least 5 grams or mL of stool which can be provided at the lab location. To get a giardia test near you at Quest Diagnostics, simply order online and submit your stool at the selected lab on the day of testing. As can be seen on the sample giardia lab report, a not detected result will be reported if no giardia is detected.
