How long do Fecal Calprotectin results take? Update: Got my results!

It depends on the lab but the longest I've had to wait is a week.
At my last hospital they did all the calprotectin tests on Wednesday afternoon. You could hand your sample in at any time but if you handed it in by 9am Wednesday you'd get the results on Thursday. But if you handed in at 10am you'd have to wait 8 days till the following Thursday...
At my current hospital they wait until the tray is full (of samples) then do the test. Because it is expensive and something to do with centrifuges and cost efficiency. So sometimes the results come the next day and sometimes the next week.
Right now I'm in a clinical trial doing calprotectin tests at home! It's a bit complicated but you get the results in half an hour.

Hi I’m a lab scientist and work in a hospital lab. At my hospital we don’t perform the test in house we send it to mayoclinic - as do so many other hospitals and lab it’s sent out somewhere else. It takes about a week. If you’re worried I would call the doc and have them call the lab to see what’s up

Thanks for the responses, sounds pretty consistently that it takes a week so that sets my mind at ease!

10 business days! Oh boy. That means I have another week to go.

I’ve just had mine done two weeks ago. It took about a week. I’m in Toronto. I’ve heard that the calprotectin takes longer because they need to cultivate the bacteria or something like that. Anyway, mine went from 2454 in June to 125 last week. Waiting to chat with the doc to see what the plan is now.

I'm wondering if you're thinking of fecal tests for bacterial infections rather than calprotectin? Calprotectin takes a while either because of the small number of samples meaning the lab only performs it every few days (because multiple samples go in the centrifuge together so it's most economical to do them in batches), or because it gets sent on to another lab. Should not depend on bacteria?
Other than that, congratulations with the huge drop. I'd say that's a very good sign
