measurement is based on pmol/L, If that is so is there a protocol recommendation anywhere regarding dosage.
Most people with MS would be to the higher range.
Europe uses both the SI Units (pmol/L) or Traditional Units (pg/mL)
Canada uses SI Units (pmol/L)
And USA and South America uses Traditional Units (pg/mL).
But you must have certainty.
Yes, people with autoimmune diseases often have a high PTH level. And they also react in a different way with vitamin D. Some need to take a high dose to drop the PTH levels others don't.
If your PTH level is 4.7 pmol/L, then you are next to the maximum range. Hence, with you second PTH exam (after 60 days) the doctor will see how your PTH reacted using this dosage. If the PTH dropped too much he/she will decrease the dose.
When people are next to the maximum range or surpass it (like my brother) the first dose is the Standard dose (1000 IU D3 X weight in kilograms).
