Calcium deposits known as limbus sign may be visible in the eyes. [7] Symptoms are more common at high calcium blood values (12.0 mg/dL or 3 mmol/L). [6] Severe hypercalcaemia (above 15–16 mg/dL or 3.75–4 mmol/L) is considered a medical emergency: at these levels, coma and cardiac arrest can result.
Frequency. 22.1 million (2015) [5] Deaths. 16,100 (2015) [6] Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material (renal calculus) develops in the urinary tract. [2] Renal calculi typically form in the kidney and leave the body in the urine stream. [2]
Dietary sources of calcium include dairy products, leafy greens, legumes, and beans. [135] There has been conflicting evidence about whether or not dairy is an adequate source of calcium to prevent fractures. The National Academy of Sciences recommends 1,000 mg of calcium for those aged 19–50, and 1,200 mg for those aged 50 and above. [136]
A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [1] These plaques are the cause of most heart ...

Calcium imaging is a microscopy technique to optically measure the calcium (Ca 2+) status of an isolated cell, tissue or medium. Calcium imaging takes advantage of calcium indicators, fluorescent molecules that respond to the binding of Ca 2+ ions by fluorescence properties. Two main classes of calcium indicators exist: chemical indicators and ...
Calcium is a chemical element; it has symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and ...
For those on low-calcium diets, there is normally 50–150 mg/24 hours, while those on a calcium-free diet will have 5–40 mg/24 hours. [1] The following reference ranges are for persons with average calcium intake (600–800 mg/day for adults):
