CLINICAL SIGNIFICANCE

Significance of Calcium

Increased calcium seen in:

  • Dehydration/ hyperproteinemia
  • Neoplasia.
  • Hyperparathyroidism (functional parathyroid tumor)
  • Hypercalcemia of malignancy (PTHrp)
  • Promotion of bone resorption (non-PTHrp)
  • Bone lysis
  • Hypoadrenocorticism
  • Idiopathic hypercalcemia of cats
  • Hypervitaminosis D.
  • Renal disease (especially horses, young dogs)
  • Renal secondary hyperparathyroidism

Decreased calcium occur in :

  • Nutritional secondary hyperparathyroidism
  • Anorexia (cattle)
  • Primary hypocalcemia.
  • Primary hypoparathyroidism.
  • Pancreatitis
  • Malabsorption
  • Ethylene glycol toxicity
  • Hypoalbuminemia
  • Renal disease
  • Hypovitaminosis D

Significance of Phosphorus

Increased Phosphorus seen in:

  • Renal disease
  • Young age (bone growth)
  • Hyperthyroidism
  • Hypoparathyroidism
  • Renal secondary hyperparathyroidism

Decreased phosphorus seen in:
