Specimen Requirement
Stool (diarrheal) specimen
Patient Preparation:
The patient should be instructed not to take any antacids, oily laxatives, or anti-diarrheal medications unless prescribed by the physician.
Collection Instructions:
Collect the specimen using a Stool Collection for Ova and Parasites Kit provided by the laboratory. The kit includes a specimen bag, an absorbent sheet, and one Total-Fix vial to preserve the stool specimen. Label vial with patient's name, unique identifier (e.g., date of birth), and date of collection. Pass the stool into a clean, dry plastic disposable container or place a large plastic bag or kitchen wrap over the toilet seat to catch the specimen. DO NOT MIX URINE OR WATER WITH THE STOOL SPECIMEN.
Semi-formed stool: Using the spork built into the lid, add stool to the vial until the liquid reaches the red fill line. Any blood or mucous should be included.
Liquid stool: Pour the stool into the vial up to the red fill line.
Tighten the vial cap completely. A leaking specimen may be unsuitable for testing. Clean the outside of the vial with rubbing alcohol or soap and water if they are soiled. Check to make sure the patient name and date of collection are still readable.
Wash hands thoroughly. Avoid contact with the Total-Fix solution inside the vial. If contact occurs, flush the affected area with water. Contact a physician immediately if irritation develops.
