Should i take calcitrol even if my intact pth is just slightly elevated and my ionized calcium is just slightly below the normal levels?

Not necessarily: Hi. For your calcium and PTH, you should only take calcitriol if calcitriol deficiency is the cause of the lab abnormality! And that would be unlikely in a person who's kidney function is normal. If vitamin D deficiency is the cause, you just take vitamin D, NOT the hormonally active form of vitamin D, calcitriol. We don't know the details of your case, so naturally can't tell you what you need.

Calcitriol: With your borderline lab values, I would NOT use rocaltrol (Calcitriol). It can result in vitamin D toxicity, severe high calcium, and kidney damage.
