Correct! In a patient with normal calcium homeostasis, the appropriate response to an elevated ionized calcium concentration is to trigger a low PTH concentration by negative feedback. While the PTH concentration in this case is technically within the normal range, it is still higher than it should be with that ionized calcium concentration, which suggests autonomous PTH production.
