All units are reported in nmol Bone Collagen Equivalents (BCE). Adult Male: 5.4-24.2 nmol BCE; Adult Female, Premenopausal: 6.2-19.0 nmol BCE.
Some patients who have been exposed to animal antigens, either in the environment or as part of treatment or imaging procedures, may have circulating antianimal antibodies present. These antibodies may interfere with the assay reagents to produce unreliable results.
