The things we do for science... Today my work includes processing rectal swab samples to assay for antiviral drugs in that compartment. I love my job... Not (today). Actually i mostly do love my job. But poo samples, not so much...
I read that Consumer Reports tests things for efficacy and smell by hiring professional sniffers (they have a more official title that escapes me). They stand behind a screen and sniff the armpits or feet or etc of volunteers on the other side (to reduce variables), and they rate the odor with and without deodorant and other products. I’m glad to know that people do such things—like your work also—to help the rest of us.
Thanks to my new puppy, I learned that tapeworms can’t be reliably confirmed from fecal tests because the eggs float to the top of the centerfuge and escape capture when slides are made. So it’s a diagnosis literally made by the process of (the dog’s) elimination. ?
I used to care for the dogs in a lab some of my undergrad years. They were involved in dental, flea product and other studies. The test was sniffing their breath after they ate Brand A or Brand B. I laughed, They were beagles and one greyhound that got loose on the campus about ever another week when it was my turn to feed her. I used to look under a microscope at puppy and kitty fecal samples.
