Thyroid/parathyroid

Hi.  I've had low vit d and been supplementing gorgeous over 2 years. Started at a 9 and now around 40.

I had a borderline high serum calcium recently (10.0, 10.1 starting high).

I asked my PCP to run it again and include a pth -- high calcium and low vit d.  Was told no because my albumin level was above 4 so it countered the high calcium.

What I didn't know was the albumin level was from May when my calcium was 9.6 and there was no albumin checked when the calcium was 10 in December.  I also had high urine calcium at this time.

So, do I need to recheck levels since the albumin wasn't checked at the same time.  I read that albumin under 4 means you need to adjust the serum calcium higher.  If it's over 4 do you have to lower, or it doesn't matter at that point?

Thanks.

"The relationship between total serum calcium and albumin is defined by the following simple rule: the serum total calcium concentration falls by 0.8 mg/dL for every 1-g/dL fall in serum albumin concentration. This rule assumes that normal albumin equals 4.0 g/dL and normal calcium is 10.0 mg/dL." Medscape - Hypoparathyroidism Workup.
