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?

@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.

Multiply your result by 1000 for the CTX value.
