@melia7 your CTX is in mcg/L, that is, micrograms per liter. To convert to pg/ml (picograms/ml, the units used here in the US), you multiply 1,000,000 then divide it by 1000:
(0.57 x 1,000,000)/1,000 = 570 pg/ml, just like @normahorn said to multiply your lab value by 1000; as 1 mcg = 1,000,000 pg and 1 Liter = 1,000ml.
Your P1NP has the same unit as used here in US mcg/L.
What's your frax score if you don't mind sharing? Will risedronate be your first bone med? What's the plan of length using risedronate?
I don't have a baseline bone markers unforturnately, although I had P1NP tested at 13 month of FORTEO which showed a tremendous boost (400). Later the bone markers were monitored periodically and they are trending nicely.

About frax score:
I have 4,9 for spine and 1,3 for hip.
The risedronate will be the first medicine, and Dr. said if the results will be OK, I can stop it in 3-4 years. It all depends on many factors.
