I believe the body secretes PTH around 2 to 4 AM. And, labs are usually not open after around 3 PM. My PTH is always normal. They put more reliance now on serum calcium, ionized calcium and PTH and much less on urine calcium. I don’t know if my urine calcium is higher just because my kidneys work well now and remove most calcium from my blood.
I read in a older text (c1968) that 24 hour urine calcium tests (to rule in or out calcium metabolism disorders) are preferably collected after a calcium-free diet for 3 days. I’ve been wondering if this is still a current recommendation or not(?).
I have also read the time of day serum tests for parathyroid hormone are performed makes a difference. Late evenings as I recall reading give you the highest level of the day. - Has anyone had experience with this?
