Don't feel bad about not knowing these things. I have met parents in the infusion center who have never been on a forum, have no clue what their kids CRP, Sed Rate or Fc is...have never even heard of FC! They are off living their happy normal lives.
I sit somewhere in the middle. I know what the tests are so if doc calls and tells me this or that is up or down, I understand what that could potentially mean but I do not get results. I go by how my kid is feeling and what is going on. I know what isn't normal for her. I let the docs worry about the blood results as with chronic conditions a little movement one way or the other is tolerable but as a lay person I have no idea what is or isn't tolerable. Plus I know me...I get results and I am off to google every little movement one way or the other so I guess it is also a bit of self preservation. But if you could strike a balance go for it. I know a few moms here have identified normal for their kid that didn't exactly fit in the lab ranges and that is a good thing...I am not that patient or advanced.
You can also just look at the IV pump...a display will run across telling you how many mg/kg she is getting.
I have caught a few things in my day..ie: labs not run or certain follow up that didn't happen but none of it earth shattering.
I do however believe that anyone inpatient should have someone with them 24/7 ..that is where most serious mistakes happen.
