Thyroid Cancer Nomogram: Risk of Postoperative Biochemical Hypocalcemia After Total Thyroidectomy

This tool predicts the probability that a patient will have low serum calcium levels after undergoing surgery for the complete removal of the thyroid gland. It can be used by healthcare professionals to plan the appropriate length of hospital stay for patients following thyroidectomy. If you are a patient, we recommend that you use this tool only in consultation with your healthcare provider.
