REASON FOR TESTING OF CALCIUM TOTAL AND CALCIUM IONIZED


Routine testing of calcium is done:

  • To evaluate metabolism of thyroid along with parathyroid gland.
  • It help to diagnose conditions that affect the bones, nerves, kidneys, heart and teeth
  • To monitor people with chronic renal failure, hyperparathyroidism, and certain types of malignancies
  • Ionized calcium is ordered in patients with numbness around the mouth and in hand and feet.

WHAT IS BEING TESTED IN CALCIUM TOTAL AND CALCIUM IONIZED


Calcium being abundant and important minerals in the body is essential for cell signalling and the proper functioning of muscles, nerves, and the heart. It is needed for blood clotting and is crucial for the formation and maintenance of bones.


Total calcium- measures the bound and free form of calcium in blood.


Ionized calcium- measures the metabolically active form of calcium in blood.


INTERPRETATION OF CALCIUM TOTAL AND CALCIUM IONIZED TEST RESULT


Hypercalcemia (increased calcium level)

  • Hyperthyroidism
  • Hyperparathyroidism
  • Prolonged immobilization
  • Excess vitamin D intake
  • Thiazide diuretics
  • Tuberculosis

Hypocalcaemia (decreased calcium level)

  • Vitamin D deficiency
  • Chronic renal failure
  • Magnesium deficiency
  • Alcoholism
  • Drugs like diuretics
  • Hypoparathyroidism

CALCIUM TOTAL AND CALCIUM IONIZED REFERENCE RANGE


Serum calcium - 8.5 - 10.2 mg/dL

Serum Ionized calcium - 4.4 -5.4 mg/dL
