Tests for Cystinuria

What we are studying

The purpose of this research study is to see if new laboratory tests are helpful in treating cystinuria. This study will also increase our knowledge about cystinuria. The best way to measure the amount of cystine that can be in urine without causing stones hasn't been found yet. Measuring the amount of cystine would help doctors predict when stones were likely to form so that they could be treated proactively. The development of a new test measures the amount of cystine in a patient’s urine. This test may provide a measurement that will potentially predict future stones and help with treatment options. Tailoring therapy to the individual patient may help medications work better while minimizing side effects. Overall, we anticipate that individualizing treatment will improve the quality of life for patients with cystinuria.
