Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, abdominal pain, or other gastrointestinal issues that could be linked to an overgrowth of *Candida albicans*. It may also be used in certain diagnostic workups for unexplained infections or immune-related conditions.

What to Expect Before the Test

No special preparation is needed. You’ll provide a sample of your stool in a provided container. If you’re using a stool collection kit, follow the instructions carefully to ensure accuracy. Avoid certain medications (like antibiotics) that might affect results, but always confirm with your provider first.

What the Test Results Mean

A positive result means genetic material from *Candida albicans* was detected in your stool. This doesn’t always mean you have an infection, but it may prompt further evaluation. A negative result means no detectable genetic material was found in this sample.

Possible Side Effects or Considerations

There are typically no side effects from providing a stool sample. If you experience discomfort or unusual symptoms after testing, discuss them with your healthcare provider.

Reference range

Negative (Candida albicans DNA not detected)N/A

Specimen: serum

No special patient preparation required. Specimen should be collected prior to initiation of antifungal therapy when possible, as antifungal agents may reduce organism load and affect detection sensitivity.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test helps identify potential *Candida albicans* overgrowth in the gastrointestinal tract, which can be important for diagnosing conditions like candidiasis (fungal infection) or assessing gut health in patients with immune disorders or chronic illnesses. While not all positive results indicate an active infection, it may guide further testing or treatment decisions.

Frequently asked questions

What does a positive result mean?
A positive result means the test detected genetic material from *Candida albicans* in your stool sample. This may suggest an overgrowth, but it doesn’t always mean you have an active infection. Your healthcare provider will discuss next steps, such as additional testing or treatment options.
Can antibiotics affect this test?
Yes, antibiotics can alter gut flora, potentially affecting test results. If you’ve recently taken antibiotics, inform your healthcare provider before the test, as they may recommend waiting or adjusting your treatment plan.
Is this test covered by insurance?
Coverage depends on your insurance plan and medical necessity. Check with your provider or insurance company to confirm if this test is approved for your situation.
