Hypocalcemia: Applications, Signs and symptoms & Causes

Hypocalcemia (US) or hypocalcaemia (UK) is a medical condition characterized by low calcium levels in the blood serum. The normal range of blood calcium is typically between 2.1 and 2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic. Mildly low levels that develop slowly often have no symptoms.…
