Why This Test Is Done
Your healthcare provider may order this test if you have symptoms like persistent diarrhea, abdominal pain, or unexplained weight loss that could suggest a fungal infection. It’s also used in people with weakened immune systems, certain medical conditions, or after taking long-term antibiotics.
What to Expect Before the Test
No special preparation is needed. Bring any stool sample collected at home (if instructed) or provide a fresh sample during your visit. Avoid using laxatives or antibiotics unless approved by your provider, as they may affect results.
How the Test Works
A small sample of your stool is cultured in a lab to grow any fungi present. After a few days, the lab identifies the type of fungus and, if possible, determines which antibiotics or antifungal medications could effectively treat it.
Possible Results and Next Steps
A positive result means fungi were detected. A negative result means no fungi were found in the sample. Your provider will discuss next steps based on your symptoms, medical history, and test results, which may include further testing or treatment recommendations.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Fungal infections in the gastrointestinal tract can cause severe illness, especially in immunocompromised individuals. Identifying the specific fungus helps tailor treatment to prevent resistance and reduce complications. Early detection and targeted therapy improve outcomes and minimize risks of spreading infection.
