The stool sampling device is a pliant laminate which can be used to obtain direct anal stool smears for use in testing for occult blood in the stool. Predetermined fold lines are disposed on the laminate, and combine with linear adhesive strips so that, after the stool smear is on the device, the laminate can be folded quickly and easily into a closed pouch. The adhesive is preferably releasable so that the pouch can be reopened for stool testing purposes. The stool-receiving layer of the pliant laminate may be removed, if desired, from the remainder of the device to be used in special chromatographic testing of the stool specimen.
