Calcium

Calcium measurements are useful in the diagnosis of parathyroid disease, some bone disorders and chronic renal disease. A low level of calcium may result in tetany.

Calcium is the most abundant vital mineral found in the body which is needed for essential functions. Calcium is required in proper cell signalling mechanisms and for the function of the muscles, heart and nerves. Additionally, calcium is important in the clotting and coagulation cascade and for the maintenance of the density of bones. Calcium gets in the body via diet or supplements. The amount of calcium in the body is very closely regulated because too little or too much are both potentially fatal. This test is used to detect calcium levels, which can be out of range in a wide variety of disorders, such as parathyroid disorder, kidney stones or osteoporosis.

This test is performed in following conditions such as:

• Kidney disease
• Symptoms of high calcium
• Fatigue and weakness
• Nausea, vomiting and constipation
• Abdominal pain
• Symptoms of very low calcium
• Abdominal and muscle cramps
• Tingling fingers
• Parathyroid disorder
• Malabsorption
