I understand your concerns... I'm sort of in the same boat. When Stephen first started remicade (Feb. 13), labs were every infusion but, at some point in the summer/fall, they moved to every other infusion. I don't know exactly when because I don't go with Stephen and then there was some confusion that the GI's standing orders were not renewed by the infusion centre! Anyway, as of now, they are every other infusion.
I agree that there isn't any harm in doing them at every infusion - other than the fact that I'm sure there are regular fluctuations in levels and seeing them too often might only cause anxiety unnecessarily. But, if not at every infusion, then why not every other infusion???
I thought I was in the exact situation you're in now and I wasn't comfortable with it either.. The reason I found out that Stephen's 'testing schedule' renewal hadn't been made was because I happened to go to one infusion and they didn't run bloodwork (when I'd thought it was being done each time). I questioned what was the 'normal' testing schedule for other patients and the nurse said some GIs do it every infusion, some every other, some once a year. I asked about Stephen's, she checked and said 'oh he doesn't have a set schedule, it's whenever the GI asks.' I was really uncomfortable with this, thinking why would the GI sporadically be thinking 'oh let's test Stephen' when he has so many other patients with much more serious issues. So, I called the remicade nurse and asked her about it and that's when we realized that the standing orders are only good for six months and should've been sent for renewal by the centre, which they didn't do! Sorry, I do ramble... my point of this is that I was not comfortable with an ad hoc schedule... in Stephen's case, at least, after his first flare, he's barely shown outward signs of inflammation, if they is the case with your son, I would not be comfortable with random checking (or if they're are signs). :ymad:
I can understand it's hard to go back to the GI after he's already said 'no' but can you explain the situation and your concerns and ask your ped to run tests every other infusion (even if it is an extra poke)?
