Serum biochemistry of a 60 year old man revealed calcium of 1.98 mmol/l and phosphate of 0.55 mmol/l with an alkaline phosphatase of 450 IU/l.Which among the following mosts suits with the above serum biochemistry? 1) Osteoporosis 2) Osteomalacia 3) Pagets Disease 4) Secondary Hyperparathyroidism 5) Renal failure

1 Answer

Answer :

Answers-2 Osteomalacia is associated with low calcium and phosphate with raised alkaline phosphatase. Serum biochemistry is normal in osteoporosis. Pagets disease is associated with normal calcium and phosphate with raised alkaline phosphatase. In renal failure when tertiary hyperparathyroidism sets in there is low calcium with raised phosphate.
