To the Editor: Clinical experience confirms the data of Ahlquist and colleagues (1) that patients find the process of stool collection for occult blood testing confusing, difficult, and distasteful. My practice has been to withhold the little wooden sticks and advise patients to dab a small amount of stool from the toilet paper directly onto the guaiac card. This method requires no additional materials (except those usually available at toilet-side). Although I admire the investigators' courage and ingenuity in tackling a dirty clinical research problem, I suggest that the solution has been right at hand all along.
