The following procedures are for Occult Blood Collections also known as stool samples.

1. Remove slide from paper dispensing envelope. Using a ball-point pen, write name, age, and address on the front of the slide. DO NOT TEAR THE SECTIONS APART.
2. Fill in sample collection date on section 1 before a bowel movement. Flush toilet, and allow to refill. Unfold flushable collection tissue and float on surface of water. Allow edges to stick to sides of bowl. Let stool fall onto collection tissue. Collect sample before it contacts the toilet bowl water.

5. Repeat steps 2-4 for the next two days, using sections 2 & 3. After completing the last section, store the slide to dry in paper envelope provided overnight.
6. After third collection, remove slide from the paper envelope and place in mailing pouch. Seal pouch carefully and immediately return to the laboratory.
