Physical checkups and blood and urine tests may not lead to diagnosis. The slow, undetected progression is why some people live for many years without knowing they have autosomal dominant PKD.

Ultrasound imaging employs no injected dyes or radiation and is safe for all patients, including pregnant women. It can als
