PTH Intact Hight out of Range

My Rheumatologist included PTH Intact lab in my bloodwork. It came back High at 86; Reference Range 10-65. My eGFR is Low at 54.80; Reference Range 60-130. Both BUN and Crea are High, Out of Range.

Calcium is normal at in mid-range, and after being on prescribed and over the counter vitamin D for over 6 months, my D level is within range.

I have fibromyalgia and osteoporosis and undifferentiated auto-immune disease. I feel TERRIBLE all the time and have for years.

The doctor is sending me to a endocrinologist next week because of the PTH Intact result.

He commented that it was odd that it was high because my vitamin D was within range. I have read that my Calcium level would typically be high if I have a parathyroid problem.

So what is going on with me? Any idea from prior experience?

I wish my patience was a virtue, but it is not.

Thanks
