N Telopeptide (Crosslinks/NTX) Urine Test
Test Code: 141093
Specimen Type: Urine
N-Telopeptide (Crosslinks/NTX) Urine Test (Labcorp)
This test measures the level of N-telopeptide Cross-links (NTx) in the urine. In addition to the N-telopeptide level, this test also measures creatinine and N-telopeptide/creatinine ratio. N-telopeptide is a marker that can help to assess bone loss and monitor treatment for conditions such as osteoporosis. The body is continually breaking down and removing old bone and replacing it with new bone as part of the process to maintain a healthy bone structure. Often, as people get older, they begin to lose bone faster than it is replaced. This can lead to bones that are weaker, more brittle, and easier to break. Bone loss can happen naturally with age or as a result of underlying conditions such as rheumatoid arthritis, crushing disease, kidney disease, thyroid disorder, and some types of cancer. As bone is broken down in a process called resorption, fragments of collagen, which N-telopeptide is a component of, are released into the blood. Measuring N-telopeptide levels can help to evaluate the rate at which bone degradation is occurring.
This test is usually ordered to monitor treatment for bone disorders such as osteoporosis. While it is not intended to screen for bone disorders, results from this test can help to confirm a diagnosis when a person has symptoms associated with bone loss. N-telopeptide urine levels are sometimes ordered along with an N-telopeptide blood test for additional information. A blood test for C-telopeptide, another marker for bone loss, is also available.
Turnaround for this test is typically 2-5 business days.
