Details
Collagen Cross-Linked N-Telopeptide (NTx), Urine - NTx is useful to assess bone resorption in patients with metabolic bone disease. The test is also useful in monitoring therapy to slow or halt osteoporotic bone loss. A decline of 30% or more of NTx over a six-month period suggests effective therapy.

Male
18–29 Years 12–99 nM BCE/mM creat
