After a couple of days of persuasion, I've finally managed to get a sample from ds2 (4) - but how much is enough?
We were given a smallish test tube and the lid had a little spoon attached - I'd say there is about a teaspoonful in there. Is that enough?
The test form says test for "faecal elastus and [can't read the next word but looks like] triducing substances" [I'm sure that's wrong but that's what it looks like] - in case that matters ....
