Instructions
Submit as for Ova and Parasite Exam (see O&P Transport collection below)
OR
Submit 2 thin air-dried smears from fresh material.
O & P Transport (Total Fix):
1. Have the patient defecate into a clean container without contaminating the sample with urine or water (these will destroy protozoan forms).
2. Examine the specimen for blood, mucus, or adult worms and preferentially sample these sites. If blood or mucus is not present, sample a representative area of the specimen.
3. Unscrew the cap of the vial of the O & P Transport and using the attached spork, place enough stool into the container to bring the fluid level up to, but not beyond the red line on the container's label.
4. Thoroughly break up the stool, replace the lid securely and shake the container vigorously.
Note: It is critical that the stool be thoroughly emulsified.
5. Replace the vial into the zip lock bag.

Transport Container
See specimen collection information. Stool should be preserved as soon as possible but no later than 2 hours after collection. Submit O & P Transport or 2 slides.
Alternate container: Samples too small to allow sufficient material to be placed into the appropriate transport container may be submitted refrigerated in a sterile screw capped container. Transport to lab within 2 hours of collection. However, strong consideration should be given to collection of another sample. Small samples are subject to rejection.
