Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Reference range

Range8.5 to 10.5 mg/dL

About

Total calcium. Most of it is bound to albumin, so a low albumin makes it read falsely low and the value must be corrected.

When it is low

Hypocalcemia: tetany, paresthesias, hypoparathyroid, vitamin D deficiency, pancreatitis

When it is high

Hypercalcemia: malignancy, hyperparathyroidism, sarcoidosis, thiazides
