Patient Scenario: Desired PTH, hyperphosphatemia and low or normal calcium
Assessing the Clinical and Laboratory Parameters
Phosphate control is suboptimal in this patient.
The PTH level is at the target range in this patient. This may be as a result of current use of vitamin D sterols in an effort to control hyperparathyroidism. However, it may be that the vitamin D sterol is adversely influencing phosphate balance by increasing absorption.
Approximately 4% of all patients are in this category.
