In brief: Needs more work-up
Low blood calcium level with elevated PTH (parathyroid hormone) result from a variety of conditions, ranging from simple low calcium or vitamin d intake (rare in us) to poor absorption thereof from intestine caused by malfunction of liver, pancreas, or kidneys.

In brief: Several things
Low vitamin d levels, or kidney failure would be among the more common causes of low calcium and high PTH levels.

Magnesium deficiency is another possibility.

In brief: Low calcium
PTH elevates in response to low calcium.
It could also be elevated due to 25 OH vitamin D deficiency.

In brief: Calcium and PTH
If you have a low calcium (c) level and a high pth, you probably have secondary hyperparathyroidism caused by chronic kidney disease (ckd).
You should see a nephrologist and have your renal function evaluated. It is likely that you have stage 3 or 4 ckd. You may need some medicines to lower your PTH level and increase your c. See a nephrologist as soon as possible for appropriate therapy.

In brief: Deficiency
Primary hyperparathyroidism usually presents with hi calcium.
Hi PTH & low calcium may be secondary to a vitamin d deficiency, maybe phosphorus retention. The answer to find is whether this could be chronic renal failure, malabsorption preventing absorption of vitamin d from gut, side effect of some drug, very poor diet, rare genetic d/o (children), etc. Please discuss with your doctor.
