Would blood test/ct pick up pkd?i was at er month ago and they found kidney stone on the left one.but my pain is in the front of my ribs not my back.

Blood test not helpf: Blood tests for PKD (polycystic kidney disease) are not currently helpful although the genetic causes for this are becoming known. Does this run in your family? A ct, mri, or, less invasively, an ultrasound will make/exclude this diagnosis. You indicated that a ct was done. If negative, i believe this diagnosis is excluded.
