1

Lab values: Paget's disease

Elevates Alk Phos; Otherwise, normal PT, serum phosphate, Ca

2

Lab values: Osteomalacia & Rickets

Vit D def; Serum Ca low, High PTH, Low Phosphate; Alk Phos normal or elevated

3

Lab values: Chronic kidney disease

Also Vit D def (but kidneys unable to respond to PTH); Serum Ca low, High PTH, High Phosphate; Alk Phos normal or elevated

4

Lab values: Osteoporosis & Osteopetrosis

All normal - Ca, PTH, Phosphate, Alk Phos

5

Lab values: Primary hyperparathyroidism

Elevated PTH, High serum Ca, Low Phosphate, Increase Alk Phos

6

Lab values: Hypoparathyroidism

Low PTH, Low serum Ca, High Phosphate, Normal Alk Phos

7

Lab values: Pseudohypoparathyroidism

End receptors not respond to PTH (i.e., high PTH but looks like hypoparathyroidism); High PTH, Low serum Ca, High Phosphate, Normal Alk Phos

8

3 Studies can be used to make dx osteoarthritis

MRI, Bone scan, Tagged WBC scan
