Serum calcium is a laboratory test to measure the amount of calcium in your blood.
Alternate Names : Ca+2, Serum calcium, Ca++
Definition
All cells need calcium in order to work. Calcium helps build strong bones and teeth. It is important for heart function, and helps with muscle contraction, nerve signaling, and blood clotting.
Ca+2; Serum calcium; Ca++
How the Test is Performed
Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic).

CBC, electrolytes, and serum calcium) may be done to evaluate metabolic disturbances and vascular disorders, TSH may be done to identify hypo- or hyperthyroidism, and more specialized endocrine tests may be helpful in establishing the diagnosis.
Calcium chloride can be injected as intravenous therapy for the treatment of hypocalcaemia (low serum calcium).
Many blood or urine tests may be done; however, the most common test is a serum calcium test. Elevated serum calcium levels can indicate the presence of a parathyroid tumor or hyperplasia (over-active cells) on one or more glands.
The parathyroid glands regulate calcium and phosphorus levels by releasing variable amounts of parathyroid hormone, which raises serum calcium levels while lowering serum phosphorus.
Tests to count the blood cells in your blood (complete blood count), to look for decline in kidney function (serum creatinine test) and to determine the amount of calcium in your blood (serum calcium test) can help rule out other types of ...

Serum biochemistry: Serum calcium is raised in 10% of cases. There is also raised gammaglobulin in the blood. There may be a raised serum alkaline phosphatase (liver function test).
Hypercalcemia is associated with parathyroid carcinoma, a rare cancer that causes significant elevations in serum calcium levels.

Infants of mothers with gestational diabetes are vulnerable to several chemical imbalances, such as low serum calcium and low serum magnesium levels, but, in general, there are two major problems of gestational diabetes: macrosomia and hypoglycemia.
Calcitriol and alfacalcidiol determine an elevation of serum calcium levels reversible in a few days after stopping the administration of the drug. Hypercalcemia caused by other derivatives may persist for weeks or months after discontinuation.
Blood tests may show elevation in serum calcium level, the changes of kidney failure, and changes in blood proteins.
Calcification of soft tissues, especially following trauma, is common. During stress, calcium is drawn out of the bones although the serum calcium may remain normal.

Laboratory testing indicates hypomagnesemia (decreased serum magnesium levels), hypocalcemia (decreased serum calcium levels), and little to no measurable parathyroid hormone levels.
Its incidence is therefore related to the incidence of the causative conditions. As a result of early detection of high serum calcium, less than 20% of patients experience hypercalcaemic-associated renal disease.

With very high levels of hypercalcemia excessive sleepiness, coma even death may occur.
The severity of symptoms for hypercalcemia depends not only on how high the calcium level is, but also on how fast the rise in serum calcium has occurred.
