Osteomark

Osteomark®

Metabolism A proprietary urine test for measuring bone loss, quantifying cross-linked N-telopeptides–NTx, which are degradation products of bone resorption and are unique biochemical markers specific for the type I collagen–found in bone. See Hormone replacement therapy, N-telopeptides, Osteoporosis.
