Urea Reduction Ration (URR) Study

Postby SaburTech » Sun Oct 01, 2017 11:33 pm

Sabur Technology in San Diego, CA is developing a urea test strip that can be used by people on dialysis to measure their blood urea before and after their dialysis in order to calculate their Urea Reduction Ratio (URR) after each dialysis treatment. The URR is a good measure of the effectiveness of the dialysis treatment. Currently, reimbursement only allows this measurement once a month, with blood sent to a clinical laboratory. The Sabur Urea test takes a small drop of blood and gives the urea result in 10 minutes. A picture of the test strip is shown at the bottom of the page. No meter is needed to read the test result, it can easily be done visually. The cost is $2.50 per test and currently it is not reimbursed by insurance. The test should be FDA cleared and ready to sell in the first half of 2018.

We are looking to get some feedback from actual patients and are willing to pay $10 if you'd answer a few questions.

I've posted the questions below.

We understand that many people would prefer not to disclose their personal contact information. We would still be interested in your feedback if you wanted to keep your identity confidential.

If you do answer the questions and include your contact information in the email, we will reimburse you with a $10 check for the first 30 people who reply.

Please email your answers with QUESTIONNAIRE in the subject line.

You can send your feedback to


1. Would you be interested in running this test? Yes____ No____
If No, why not?

2. Do you think that you would test yourself before and after every dialysis treatment?
Yes _____ No _____

3. If this test was offered by the clinic, would you pay out of pocket for this test at every dialysis treatment? Yes _____ No _____

4. Do you have any comments to add about this test or how it might be useful? __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Thank you for your time and consideration.

I think this test is not really necessary, the information obtained is not much use, and the monthly test are perfectly adequate.
