Specimen Collection Procedure
- Remove slide from paper dispensing envelope. Using a ballpoint pen, write your name, age and address on the front of the slide. Do not tear the sections apart.
- Fill the sample collection date on section 1 before the bowel movement. Flush toilet, and allow to refill. Unfold flushable collection tissue and float on the surface of the water. Allow edges to stick to sides of bowl. Let stool fall into collection tissue. Collect sample before it contacts the toilet bowl water. You may use any clean dry container to collect your sample.
- Open front of section 1. Use one stick to collect a small sample. Apply a thin smear covering Box A. Collect second sample from different part of stool with same stick. Apply a thin smear covering Box B. If used, flush collection tissue and discard stick in a waste container. DO NOT FLUSH STICK.
- Close and secure front flap of section 1 by inserting it under tab. Store slide in this paper envelope until the next day. Important: This allows the sample to air dry. Do not place sampled slide in any moisture-proof material such as plastic bags. Do not store slide in refrigerator at any time.
- Repeat steps 2-4 for the next two days using sections 2 and 3. After completing the last section, store the slide to dry in this paper envelope overnight. The next day, remove slide from this paper envelope and place in the mailing pouch. Seal pouch carefully and immediately return to your doctor or laboratory.
