What does this test include?
This direct stool test looks for the specified antigen, toxin, or group of markers in the submitted specimen. It detects components of an organism rather than an antibody response.
Why might it be ordered?
- For acute gastrointestinal symptoms when clinically appropriate.
- To distinguish several listed organisms or markers that are included in the combined test.
- As part of an assessment that also considers symptoms and other microbiology tests.
What sample is needed?
A stool specimen is required. Confirm the container, minimum amount, delivery time, and whether storage before delivery is permitted.
How should you prepare?
No special dietary preparation is stated. Report medicines and follow clean-collection instructions; do not mix the specimen with water or cleaning products.
How are the results reported?
The report states whether the relevant marker was detected in this specimen. A reactive result is interpreted with symptoms, while a non-reactive result does not exclude every possible cause.
