Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like persistent diarrhea, unexplained weight loss, or signs of a fungal infection (e.g., persistent thrush, skin rashes, or abnormal lab results). It’s also used in people with weakened immune systems, chronic illnesses, or those taking medications that increase infection risk.

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 stool softeners or laxatives unless directed by your provider.

How the Test Works

A small sample of your stool is cultured in a lab to grow fungal organisms, if present. Sensitivity testing identifies which antifungal drugs could effectively treat any detected fungi.

Results and Follow-Up

Results take 5–14 days. If fungi are found, your provider will discuss next steps, including treatment options and monitoring. Follow-up may involve retesting or additional tests to confirm eradication.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
