Because parasite morphology will not be preserved, specimens sent on diaper or tissue paper are not acceptable to the laboratory because of risk to lab personnel. Grossly leaking specimens may not be processed. Specimen containing interfering substances (eg, castor oil, bismuth, Metamucil®, barium specimens delayed in transit and those contaminated with urine) will not have optimal yield; unlabeled specimen or name discrepancy between specimen and test request label; expired transport device; specimen not received in O & P preservative transport containers with formalin and PVA. |
