Hi Dr. Lupo,
I asked my physician to do a parathyroid, total calcium and ionized calcium test. I am still waiting on the ionized calcium, but I wanted to let you know the other results and get your thoughts.
According to my doctor, my calcium had been in the normal range until last November. I didn't ask if it was high normal, but November is when I started having more palpitations and anxiety problems.
November -- Ca was high (I assume over 10.2, as he actually said high)
January 4 -- Ca was 10.3 (range 8.5 - 10.2)
January 31 -- Ca was 10.5
January 31 -- PTH was 36.8
January 4 -- Urinalysis for kidney stones all within normal range. I have a 14-year calcium stone history, and have nearly 20 -- 3 in the past 6 weeks.
Is the PTH level inconclusive? Will the ionized calcium result prove/disprove possible hyperparathyroidism?
I haven't had a thyroid panel done since this all started at the end of November. I have a family history of hyperthyroidism (Dad, sister) starting around the age of 35 (I am 34). Would the thyroid raise calcium levels, or am I likely just someone that functions at a higher calcium level?
What are your thoughts?
Thanks again for your help.

The PTH is inappropriately normal for the high calcium and calcium stones. The normal ionized calcium does not alter this as calcium will fluctuate between normal and high with hyperparathyroidism. My guess is that you have hyperparathyroidism, but would make sure that the TSH, FT4, FT3 are okay to exclude hyperthyroidism. Check out parathyroid.com for more info regarding parathyroid problems.
Thanks.
