Risk Understanding By Yourself (RUBY) allows you to assess your risk for diabetes and its complications, so as to attain early intervention and prevent deterioration.
Risk scores

Risk score is a value ranging from 0 – 30 in female and 0 – 28 in male. If your risk score is 16 or above, it is advised that you visit your family doctor where you may need to undergo a more comprehensive test such as the oral glucose tolerance test (OGTT) or diabetes risk assessment.

Risk score will change in time when there is a change in your health status or lifestyle. We recommend you to repeat the RUBY test every 6 months. RUBY risk score is calculated based on previously published work.


The assessment for diabetes risk factors provided by this software is for reference only and should not be construed as a medical diagnosis. Users are encouraged to visit their family doctor for further advice.

Our risk assessment scoring system has been validated with southern Chinese only. If you are a descendant from another region, please use the test as a reference and ask your family doctor for further advice.
