Overproduction of PTH can result in excessive increase in blood calcium levels. BUT remember these are not part of thyroid gland. These are only located near thyroid. C-cells are part of thryroid gland that produce calcitonin. And this hormone is responsible for reducing the calcium level in blood and not increasing.
