The present study of the bone markers in the healthy Thai females and males enrolled 588 females and 53 males
with age range from 25 to 42 years. The potential modification of variations was controlled. The bone resorptive markers,
betaCTx, of females and males were 0.3 + 0.169, 0.412 + 0.191 ng/ml respectively. The bone formation markers, PINP, of
females and males were 44.5 + 19.92, 58.1 + 37.7 ng/ml respectively. These markers could be recognized as the standard
values for comparison.
