ReEvaluating the Ca x P Product Renal Fellow Network

Presently, the KDOQI guidelines state that nephrologists should attempt to maintain the Ca x P product below 55 in order to minimize pathologic calcifi ion. I had always been taught that if the Ca x P product exceeds 55, there is a tendency for calcium phosphate to precipitate and deposit within the walls of blood vessels.
