NTX Blood Test - More Information
The NTX test, sometimes known as an NTX blood test, NTX lab test, and a N-telopeptide lab test, measures the NTX blood level.
NTX (or NTx) is a blood marker that can be helpful in assessing how quickly one's bone density is remodeling and breaking down. Formally known as amino-terminal collagen crosslinks, N-terminal telopeptide might also be helpful in assessing the bone mineral density and skeletal changes when a person is started on antiresorptive therapy. Additionally, the NTx blood test helps stage the risk of bone mineral losses in postmenopausal women. Some people consider the CTX test more useful as it might be more stable when considered in the context of bone metabolism.
Getting an NTX test at a Quest Diagnostics lab near you is relatively simple. Once you order your test, you can make an appointment and get your blood drawn on the day of your test. This NTX uses an enzyme immunoassay methodology and results come back relatively quickly. As can be seen on the sample NTX lab report above, N-telopeptide blood levels are reported as a numerical value and can be compared against the reference range provided by the lab.
The NTX level test is a component of the osteoporosis test panel.
