What does a calcium level of 8 mean?
A normal serum calcium level is 8-10 mg/dL (2-2.5 mmol/L) with some interlaboratory variation in the reference range, and hypercalcemia is defined as a serum calcium level greater than 10.5 mg/dL (>2.5 mmol/L).
What does it mean when serum calcium is low?
What happens when calcium levels are low? Hypocalcemia, also known as calcium deficiency disease, occurs when the blood has low levels of calcium. A long-term calcium deficiency can lead to dental changes, cataracts, alterations in the brain, and osteoporosis, which causes the bones to become brittle.
What is a low calcium number?
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.
What is the most common cause of low calcium?
The most common cause of hypocalcemia is hypoparathyroidism, which occurs when the body secretes a less-than-average amount of parathyroid hormone (PTH). Low PTH levels lead to low calcium levels in your body.
Is low calcium an emergency?
Severe hypocalcemia, defined by a serum calcium <1.9 mmol/L (7.6 mg/dL), is often considered an emergency because of a potential risk of life-threatening cardiac arrhythmias or seizures (6, 7, 8, 9, 10, 11).
What is a dangerously low calcium level?
What diseases cause low calcium?
Vitamin D deficiency, low parathyroid gland function, gut disorders, and kidney disease are among the more common causes of hypocalcemia. Rarely, you can become deficient if you’re not getting enough dietary calcium. Work with your doctor if your calcium levels are low to discover and treat the underlying cause.
Who is most at risk for calcium deficiency?
There are three major population groups that are at highest risk for dietary calcium deficiency. These include women (amenorrheic, the female athlete triad, postmenopausal), individuals with milk allergy or lactose intolerance, and atrisk groups for dietary deficiency intake (adolescents and the elderly).

What is a normal serum calcium level with albumin?
– Total serum calcium may be less than 8.5 mg/dl. Serum calcium levels should be evaluated with serum albumin. For every 1.0 mg/dL drop in serum albumin, there is a 0.8 – 1.0 mg/dL drop in the total calcium level.
How do doctors check calcium levels for calcium deficiency?
If your doctor suspects calcium deficiency, they’ll take a blood sample to check your blood calcium level. Your doctor will measure your total calcium level, your albumin level, and your ionized or “free” calcium level.
What is the normal calcium level in the human body?
Normal Blood Calcium Levels in Humans. In our bodies, calcium is a mineral that makes up our bones, as well as a salt that dissolves in our blood and regulates bodily function. At UCLA, the normal range for blood calcium level is 8.6 to 10.3 mg/dL.
