What level of calcium is considered hypocalcemia?
Consequently, what level is considered severe hypocalcemia?
Severe hypocalcemia (serum calcium < 7 mg/dL [< 1.75 mmol/L]) may cause hyperreflexia, tetany (paresthesias of the lips, tongue, fingers, and feet, carpopedal and/or facial spasms, muscle aches), or generalized seizures.
Just so, what level of calcium is too low?
Sustained low calcium levels in your blood may confirm a diagnosis of calcium deficiency disease. Normal calcium levels for adults can range from 8.8 to 10.4 milligrams per deciliter (mg/dL), according to the Merck Manual. You may be at risk for calcium deficiency disease if your calcium level is below 8.8 mg/dL.
An intravenous calcium bolus will raise serum calcium for 2-3 hours, so patients with hypocalcemia should also be started on a longer-lasting treatment. Intravenous calcium infusions are often used for patients with adjusted calcium levels less than 7.0-7.5 mg/dL [1.75-1.875 mmol/L], even if they are asymptomatic.
