N-Telopeptide Cross-links (NTx) Urine Test

Also Known As

Collagen Cross-linked N-telopeptide

The Purpose of the NTx Test

The N-telopeptide Cross-links (NTx) test is a tool used to assess bone health or diagnose a medical condition that detracts from the condition of your bones. The test does this by checking the urine’s level of NTx, which is produced when there is bone resorption or breakdown. By measuring the NTx levels, doctors can evaluate any bone loss and determine if you are at risk for osteoporosis or another bone-related disease.

What Does the Urine NTx Test Measure?

The N-telopeptide test measures the amount of NTx molecules in your urine sample. When the body breaks down bone tissue faster than it replaces it, the level of NTx increases. The NTx test can help detect early bone loss and help you and your doctor develop an effective treatment plan.

Who Should Take an N-Telopeptide Urine Test?

The NTx test is recommended for people who are at risk for bone loss or have a family history of osteoporosis. Postmenopausal women may also want to take this test because their lower estrogen levels raise their risk of bone loss. Finally, the N-telopeptide test can be used to monitor patients who have bone-related medical conditions to ensure their treatment plan is working.

Urine NTx Test Preparation

There is no specific preparation required for the N-telopeptide urine test. However, you should make sure to follow the instructions for collecting your sterile urine sample so the test results are accurate.

Urine Culture Lab Test Results

The reference range for an NTx test is 0 to 62 nM BCE/mmol creatinine for men, 0 to 64 nM BCE/mmol creatinine for women ages 20 to 49, and 0 to 89 nM BCE/mmol for women older than 49. If you want to review your results with an experienced physician, schedule a telehealth visit with one of our board-certified doctors.
