The problem with that idea, is that a fecal test involves using a special solution, mixed with the feces to separate eggs out of stool, then it is examined under a microscope, or some tests centrifuge the sample prior to microscope. If you have not been trained, you won't know what you're looking at. You may get false results. Check with your vet to see if there is an after hours drop off location, (the vet I used to work at had a box near the door, we would collect any "gifts" left after hours in the am). This would possibly make it easier for your husband to drop one off?
