Hi Doctor, I am Srikanth from Delhi, India. I went for a comprehensive health checkup (Quest Diagnostics), recently. All tests were normal except PTH and Vitamin D. PTH is high at 123 and Vitamin D is low at 2.35. I have consulted a doctor here, who suggested to go for the weekly Calcitriol Sachets and redo the tests after 3 months. Please share your views on this. [My age is 41 years, Height 171 cms, weight 72.50 Kgs and healthy]. Thank you in advance
