Special Info
Testing performed only on stool specimens. Do not send swabs. Formalin preserved stool is preferred. Fresh specimens must be less than 6 hours old. Patient Preparation: No administration of barium, bismuth, psyllium (Metamucil), castor oil, mineral oil, or administration of antiamoebic drugs within one week prior to the test. Positive Cryptosporidium results are confirmed with microscopy after concentration of the specimen. CPT codes that may apply include: 87015, 87206, 87207.
Clinical Info
Average TAT for this test is 34 hrs. The Cryptosporidium test uses microscopic staining methods (Modified Acid Fast) to rule out infection due to Cryptosporidium, Cyclospora, and Cystoisospora sp. in stool. Infection with these agents generally occurs through ingestion of contaminated water or food and causes diarrhea. Immunocompromised patients are more susceptible to infection. One negative result does not rule out the possibility of infection.
