Definition. Hypocalcemia, a low bood calcium level, occurs when the concentration of free calcium ions in the blood falls below 4.0 mg/dL (dL = one tenth of a liter). The normal concentration of free calcium ions in the blood serum is 4.0-6.0 mg/dL.
The first step in diagnosis is a blood test to determine your calcium levels. Your doctor may also use mental and physical exams to test for signs of hypocalcemia. Your doctor may also test for Chvostekâs and Trousseauâs signs, which are both linked to hypocalcemia. Chvostekâs sign is a twitching response when a set of facial nerves is tapped. Trousseauâs sign is a spasm in the hands or feet that comes from ischemia, or a restriction in blood supply to tissues.
