In many cases, your doctor can identify polycystic kidney disease based on imaging tests of your kidneys and other organs to make the diagnosis. However, genetic tests can also be used when imaging test results are inconclusive.

For genetic testing, special blood tests are given to you and to family members who are known to have or not have the condition. Results of your blood test are compared to those of your family members.

Genetic testing is often used when one family member considers donating a kidney to another family member for a living-donor kidney transplant.
