Understanding Stool Testing
Stool tests examine a collected sample for a specific laboratory purpose, such as blood, infection, inflammation, or digestive function.
Why is this important?
Understanding the purpose and limits of laboratory information can support a more informed conversation with a qualified healthcare professional.
How laboratory testing relates
Collection instructions differ by test. Avoid mixing the sample with urine or toilet water and use the supplied container when the laboratory instructs you to do so.
Before testing
Preparation is test-specific. Follow the instructions given for the exact test and contact the laboratory if fasting, timing, medicines, or specimen collection is unclear. Do not stop medicines unless a qualified professional tells you to.
