Ionized Calcium 4.65, PTH 133, Calcium 10.3, Vitamin D 7, Phosphorus 4.9, recurrent Kidney stones. Thyroid lobe,  two parathyroids removed in 2004.

Uncertain: These test results don't add up to a straight forward answer. However, I would be concerned about the possibility of recurrent primary hyperparathyroidism. You should take Vit D to eliminate Vit D deficiency as a cause for high PTH levels. Once this is done, if you still have high PTH with high calcium levels, you have recurrent primary HPTH and will need surgery again. ...Read more

What might cause my liver and kidneys to not extract any vitamin d?

They do not extract: The liver and kidneys do not extract vitamin d, they activate it into forms that are usable by the body. Native vitamin d has no effect until it is activated.

I already take 3700 iu of vitamin d, why does it keep showing up that I am deficient? My thyroid and kidneys are fine.

I already take 3700 iu of vitamin d, why does it keep showing up that I am deficient?  My thyroid and kidneys are fine.

Not enough D: It sounds like you are taking enough vitamin d to maintain healthy levels, but not enough to raise deficient levels into the healthy range. You may need to take very high doses of vitamin d for 3 months or more to get your levels into a healthy range. Other possibilities might include poor absorption of fat and fat-soluble vitamins like vitamin d, or taking steroids. Work w/ your doc on this. ...Read more

What does lack of vitamin d have to do with kidneys?

If my Vitamin D level is 19, do I need to have the kidneys, thyroid, or calcium levels checked?

If my Vitamin D level is 19, do I need to have the kidneys, thyroid, or calcium levels checked?

Likely need Vit. D: At 65, you likely have basic labs performed, and hopefully on a routine basis. Typical labs will give a basic exam on electrolytes and waste products. A Complete Metabolic Panel and thyroid test will give a view of organ function. Vitamin D has a large therapeutic index and the likelihood of it being low increases with age. B12 also follows this pattern. ...Read more
