Overview

Collagen crosslinked N-telopeptide (NTx) is a breakdown product of bone collagen released when bone is resorbed. A urine NTx test measures bone turnover and resorption rates. Elevated levels indicate accelerated bone loss, which occurs in osteoporosis, menopause, or certain metabolic conditions. This marker helps assess bone health, monitor osteoporosis progression, and evaluate treatment effectiveness. It's particularly useful in women at risk for osteoporosis and in monitoring antibone loss therapies.
