levels of Ca, Phosphorous and alkaline phosphatase in
a.Osteoporosis
b.Osteopetrosis
c.Osteomalacia
d.Osteitis fibrosa cystica
e.Osteitis deformans

where r u, zuzuethflorida?

[ArchivalUser]

a.-------normal ca, p and alk.phosphatase
b------normal ca, p and alk.phosphatase
c------low ca, low p and incr alk.phosphatase
d.-----caused by hyperparathyroidism---so, incr pth,,incr ca, low p and incr alk.phosphatase
e---aka paget's dz----normal ca, normal p but incr alk.phosphatase

Haven't seen your question. Was difficult though!
One thing which helps with Alkaline phosphatase is it is almost always increased in almost all diseases of liver, bone or systemic diseases affecting them.

Thanks

1) in osteomalacia:
regarding serum phosphorus can have inc phosphorus :
if there is high serum phosphorus probabaly pt along with it might be in renal failure

2) in pagets there are increased levels of urinary hydroxyproline also

thank u, cancer123.
that's interesting to know abt osteomalacia.

u r right about the paget's dz.
cuz, in paget's dz, the there is increase in both osteoblastic and osteoclastic activity.
OSTEOBLASTIC ACTIVITY----------Increase in alk.phosphatase
OSTEOCLASTIC ACTIVITY----------Increase in Acid phosphatase, urinary dihydroxypyridinoline(most reliable of all), urinary hydroxyproline and TRAP.

ostitis fibrosa cystica also could be seen in renal failure and secondary hyperparathyrodism. in this case phosphate would be high, which is the triggering event.
