My 20 yr old son's calcium level is 10.4 (normal should be: 8.6 - 10.2) and PTH is 6 L (normal should be 10 - 65). He also is 21 L for vitamin D (normal should be 30 - 100). The endocrinologist said for him to take vitamin D3 1000IU's per day. The endocrinologist said that parathyroidism was ruled out because my son's PTH was very low at 6 L. Wouldn't taking vitamin D3 elevate his calcium (hypercalcemia) instead of lower it? For the past 6 months, my son has had symmetrical pain in his wrists, ankles, numbness/tingling in hands/feet, extreme fatigue and his leg bones hurt to the point of not being able to walk more than 10 minutes. We've been to 8 specialists, my son has had every diagnostic test imaginable and no Dr. can diagnose him! It's been so frustrating. Also, his B6 levels are 31 H when normal range should be 2.1 - 21.7. What is the cause of elevated B6 and elevated calcium and how do we lower it? How do we get these blood numbers back to normal? Also, his Albumin/Globulin Ratio is 2.4 H when normal range should be 1.0 - 2.1. Thank you
