University of Madison also has many good videos on their site regarding calcium & PTH. Their information states if calcium is even higher at 10.3 ( let’s say) the PTH should be more like 15..or very low.
My primary told me today calcium fluctuates widely & who knows maybe you drank a glass of milk before your lab draw.
What I have read & researched is that it’s a very precise mechanism in the body…it shouldn’t “fluctuate” & 10’s are too high for an adult.
