Cryptosporidium RNA (Qualitative) in Stool Specimen by Gene Probe Detection

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, abdominal pain, or weight loss, especially if you’ve traveled to areas with poor sanitation or have a weakened immune system. It’s also used in diagnosing suspected cases of cryptosporidiosis in patients with HIV/AIDS or other immunocompromising conditions.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to collect a fresh stool sample in a provided container. If you’re on antibiotics or have recently had a bowel movement, your provider may give specific instructions to ensure accurate results.

What the Results Mean

A positive result means Cryptosporidium parasites were detected in your stool, suggesting an active infection. A negative result means no parasites were found, but it doesn’t rule out other possible causes of your symptoms. Follow-up testing or additional evaluation may be needed.

Common Causes of False Results

False negatives can occur if the sample wasn’t collected or processed correctly, or if the infection is very mild. False positives are rare but may happen if there’s contamination or if other substances interfere with the test. Your provider will discuss results in detail with you.
