Bone turnover markers (CTX and P1NP): do you have a baseline?

About values of bone markers. I have just made the tests (and I have yet to start a treatment (risedronate).
CTX was 0,57 microgram per liter and nearby they mentioned 0,18-1,06 microgram for postmenopausal women.
P1NP was 76,2 microgram per liter, and it was noted that normal value should be from 20,25 to 76,3 microgram.
I am not sure how micrograms are translated to picograms, which are used in the USA. Sure, it is interesting to compare values before and after treatment. What were yours?

Multiply your result by 1000 for the CTX value.

@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.
