New test results : Calcium 10.5 ( high again!) PTH : 55 (high normal) Albumin : 5.3 (high and out of range) - normal range is under 5 . Cause? dehydration - I have had a white coated tongue since my calcium tested high for the first time. Cause of dehydration? Diabetes insipidus( I have 90% of the symptoms). Cause of Diabetes insipidus? It can be calcium ,or something else : http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001415/ This is all my own understanding, and I am waiting for my ionized calcium , and urine calcium results.
