If a patient had vitamin d deficiency for years will other blood results such as calcium show high or low levels?

In brief: Likely normal or low

Prolonged vitamin d deficiency can be associated with low circulating levels of calcium. Often, though if there is adequate dietary calcium intake and even occasional vitamin d intake through diet or production through sun exposure, circulating calcium levels can be normal (although other lab values such as parathyroid hormone (PTH) or alkaline phosphatase will be high and serum phosphate low).
