Long time listener, first time caller.
I (41M) first started paying attention to my calcium when the results came back high in August of 2022. I was 37 at the time. Here are my calcium labs as far as I have records (all normal ranges in this post are capped at 10.3).
06/21/22- 10.2
07/18/22- 9.9
08/23/22- 10.4
04/06/23- 10.3
10/09/23- 10.0
04/24/24- 10.0
01/15/25- 10.0
10/07/25- 10.2
04/28/26- 10.4 (Vitamin d was 29 with normal starting at 30, only ever Vitamin d test)
I bought my own PTH test in October of last year after the numbers crept back up. That test showed a calcium of 10.0 and a PTH of 29. Those didn't seem concerning to me so I dropped it. Then last month the calcium came back high again.
As is common, my PCP brushed my concerns aside though I'm pressing for a calcium, pth, and vitamin d all in one go. I'll buy one myself if she doesn't want to give me one.
I also have some symptoms (bad inability to concentrate, hypertension, anxiety, high heart rate, and palpitations to name a few) but they're maddeningly non-specific.
I've read a lot about calcium levels repeatedly in the 10s being concerning after 35 and even more concerning after 40. But other places seem to be less concerned about low 10s calcium.
I'm just not sure what to think. I can go straight to an endo with my insurance. And there are a couple good parathyroid docs in Atlanta where I live. I just don't know if my numbers are at that point.
