- Question from Lucy: Are urine tests a good measure for calcium loss?
- Answers - Charles Shapiro Urine tests are a good measure for bone turnover. They're very sensitive for bone turnover, but I don't think I mean calcium per se. I'm not aware of the test that measures calcium loss in the urine.
- Marisa C. Weiss, M.D. Some physicians like to get the urine test, which is called the N-Telopeptide. This test looks at the balance of the bone turnover. If the DEXA scan that you get is not giving your doctor a good enough idea of whether the medication is working or not, your doctor may order a urine test to help figure it out. It is an easier and less expensive test to get than the DEXA scan. Some doctors may want to get both the DEXA scan and the urine test. The DEXA scan is usually done once a year. The urine test could be done at the 6-month interval just to get a sense of whether the bone turnover is in proper balance or not in response to the medication and lifestyle regimen that you are pursuing.
