An almost painless removal of blood taking 5 seconds versus a home fecal test.

First you have crap in a paper tray (as you cant get toilet water in the sample), wipe your bum, put on gloves, then you have to scoop a reasonable amount of crap (using the plastic spoon provided) into a test tube yourself. Quite hard to hold your nose while doing that (if you put your gloves on before taking a crap you may not want to hold your nose). Repeat the following day to complete the number of samples required.

I prefer the easy needle thanks.
