The upper limit of normal is 1.35 mmol/L. But don't worry.
Calcium reports must always be interpreted along with patient symptoms. And ionised calcium can vary with blood pH.
Check your serum total calcium, phosphorus, serum
albumin and serum
alkaline phosphatase.
I'm curious why serum calcium was done for you in the first place.
Symptoms of high calcium are excess thirst and urination, bone pains, etc. If you are having any of these, just consult a physician.
Dehydration, Fast breathing, Fever are some conditions that shift ionised calcium above normal range.
