Hi, I recently did a blood test and am worried about my calcium level. My calcium level was 2.70 mmol/L and corrected calcium is 2.58 mmol/L, with Albumin been 49. The only blood test I have previously to compare to was one from 14 years old patientago. Then calcium was 2.46 and corrected calcium was 2.32. The range I have for normal calcium range on my blood test is 2.10 - 2.60 - though I understand some labs use 2.50 as the upper limit. My phosphate level is 1.18 mmol/L. My question is should I be concerned, could this be an indication of Hyperparathyroidism? Is this level a risk to calcification of the arteries? My doctor said it isn't anything to be concerned about but I would like a second opinion as I am on the high end. I have read that even a slight elevation is not good.
