What usually happens next

It's usually repeated with albumin (a corrected calcium) and a PTH. In an otherwise well person, an overactive parathyroid gland is the most common reason.

Calcium and vitamin D supplements, thiazide diuretics and dehydration can push it up too.

What a high calcium usually means, and its common causes

When a calcium can read wrong

Most calcium in blood rides on albumin, so a low albumin makes total calcium read low and dehydration makes it read high. A long tourniquet can nudge it up. A corrected or ionised calcium settles it.
