A method for determining the presence of occult blood in the bowl of a toilet includes the steps of suspending from the seat of the toilet an absorbent test sheet carrying a test reagent, defecating onto said sheet, flipping said sheet over to deposit the fecal matter in the bowl water, applying a developing solution to said sheet and observing whether a portion of said sheet is dyed blue. Preferably the test sheet is an absorbent paper printed or impregnated with guaiac.
