A
DEXA scan (measure of bone mineral density).
Serum calcium and phosphate levels are normal.
2
Q
What abnormal biochemical findings can be found in osteomalacia or rickets?
A
Low calcium.
Low serum phosphate.
High serum alkaline.
3
Q
What abnormal biochemical findings can be found in hyperparathyroidism?
A
Serum PTH is elevated.
Calcium is high.
Phosphate is normal or low.
4
Q
What abnormal biochemical findings can be seen in hyperparathyroidism?
A
Very high serum calcium levels -> emergency treatment of IV fluids, bisphosphonates and calcitonin.
