Calcium (serum)

DESCRIPTION:
Calcium is one of the most important minerals in the human body. Approximately 99% of calcium is found in bones.

DETERMINATION:
Calcium in serum is determined by the photometric method with o-cresolphthalein. The sample for analysis is serum or urine. Serum samples for analysis must not be hemolytic. The stability of the sample is 10 days at 2°C – 8°C.

CLINICAL SIGNIFICANCE:
High serum calcium concentrations have been observed in cancer, vitamin D overdose, increased kidney retention, osteoporosis, thyrotoxicosis, and hyperparathyroidism. Decreased serum calcium values have been observed in hypoparathyroidism, pseudohypoparathyroidism, vitamin D deficiency, malnutrition, and interstitial malabsorption.

RESULT:
The reference interval depends on gender, age and the method of determination. The reference interval is displayed on each validated result.
