Common automatic estimation of eGFR by diagnostic laboratories have to be useful tool in this matter. It is also important to avoid combinations of potentially nephrotoxic drugs. In case of the appearance of first symptoms of toxic renal injury specific activities dependent from the character and severity of pathological changes are necessary.
