Vitamin D cannot be used as a global predictor of post-thyroidectomy hypocalcaemia

In our population, pre-operative vitamin D level was not a reliable predictor of post-thyroidectomy hypocalcaemia. Because of population-based differences in vitamin D metabolism and assay variability, universal cut-off values remain impractical. These findings highlight the need for further research to establish population-specific thresholds for vitamin D in predicting hypocalcaemia risk.
