This test is rarely positive, and is no longer performed as a routine test. A staff physician or a member of the Infectious Diseases Service at the client site must contact the MLabs Client Services Center and consult with the laboratory regarding clinical necessity for the test before the specimen will be processed. Collect in stool culture transport available from MLabs. Add stool specimen to transport until liquid reaches fill line. Emulsify specimen thoroughly in transport fluid. For optimum recovery, send immediately. If specimen must be stored, refrigerate immediately after specimen collection. May be refrigerated up to 24 hrs. Indicate specimen source and collection date/time. If an unacceptable specimen is received, the client will be notified and another specimen will be requested before disposal of the specimen.
