Cystatin-C Clinical Survey

Thank you for helping us evaluate the potential benefits of adding Cystatin C testing to the list of insured medical tests in Ontario.
Cystatin C is a small molecule that is freely filtered by the kidney and has minimal secretion or reabsorption. It is generated at a constant rate, is not affected by diet or muscle mass, and is more strongly associated with risk for cardiovascular events and all-cause mortality. Cystatin C can be used independently or in conjunction with serum Creatinine as a marker for estimating kidney function (eGFR) and has key advantages for certain patient groups including those of African descent and extremes of muscle mass.

You have been invited to take part in this survey because you ordered a Creatinine test for at least one patient between April 2021 and August 2021. You would have received Cystatin C test results in addition to your Creatinine test results as part of a New Tests and Technology Fund pilot through the Ontario Ministry of Health.
