What Is the Normal Calcium Level in the Blood?
Normal calcium levels in the blood range from 8.8 to 10.4 mg/dL in adults and 6.7 to 10.7 mg/dL in children. However, levels outside this range are not always a concern; doctors may interpret results differently based on the age of the patient and other health factors.
Those suffering from abnormally low calcium levels may experience muscle cramps, spasms, and tingling around the mouth. Patients with high calcium levels may feature nausea, vomiting, lack of hunger, weakness, constant urination and bone pain. Having a calcium test can also indicate whether there are problems with the parathyroid glands, kidneys or pancreas and detect the presence of certain cancers.
