Question regarding fecal calprotectin testing

I've been previously diagnosed with microscopic ulcerative proctosigmoiditis (UC), but have been in remission for a long time. I also have IBS so I still have symptoms to some degree but I would keep an eye on things by doing fecal calprotectin testing to make sure my levels were normal. I'd had some bowel discomfort/rectal burning and other symptoms around October-November last year so I had two fecal calprotectin sample tests done in November two weeks apart, one was 152µg and the other one two weeks later was 105µg. I spoke to my IBD nurse who said it wasn't overly high, only mildly elevated and to repeat in 6 weeks time (so around now.)

I've recently been on Doxycycline as a preventative for skin inflammation issues (once a day 100mg) which I recently finished a 6 week course of just this week. My question is whether I should wait until it clears from my system fully to do the retesting of the fecal calprotectin or whether I should just go ahead with it. I don't know whether this sort of thing is affected by it, but I don't want to mess up the test and get an inaccurate result.

I'm also on a PPI for chronic gastritis and I know the PPI can mildly elevate levels, but I've had fecal calprotectin tests in the past while on this which weren't affected by this medication.

Just figured I'd see if anyone else has had testing done while on any antibiotics like this and if I should be waiting before I test so I get an accurate result
