What This Test Measures

The test involves growing stool samples in a controlled environment to detect and identify fungal organisms. If fungi are present, they will grow and can be identified under a microscope or through further testing.

Why It’s Done

Your healthcare provider may order this test if you have symptoms like persistent diarrhea, abdominal pain, or other signs of gastrointestinal infection, especially if you’ve been taking antibiotics or have a weakened immune system.

Preparation

No special preparation is needed. Bring a fresh stool sample to your appointment. If you’re taking antibiotics, inform your provider before testing, as this may affect results.

What to Expect

The sample is sent to a lab where it’s cultured for up to 7–14 days. Results may take longer if specific fungal identification is needed. You’ll receive a report once the lab confirms or rules out fungal growth.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

This test is crucial for diagnosing fungal gastrointestinal infections, which can cause chronic diarrhea, weight loss, or other symptoms. Early detection helps guide treatment with antifungal medications.
This test is qualitative, meaning it only tells whether fungi are present or not, not their exact type or amount. False negatives can occur if the sample isn’t collected properly or if the infection is mild.
Common fungal causes in stool include *Candida* (yeast), *Aspergillus*, or other molds. Symptoms like bloating, nausea, or unexplained weight loss may signal an infection.
If you have a history of fungal infections, immune disorders, or recent antibiotic use, your provider may recommend this test. Follow-up may include additional tests if fungi are detected.
How long does it take to get results?
Results typically take 7–14 days, depending on lab methods. If your provider suspects a specific type of fungus, further testing may extend the wait time.
