Patienter med kronisk nyresvigt, som får erytropoietin, bør have deres hæmoglobin (den ilttransporterende del af de røde blodlegemer) målt jævnligt, indtil niveauet er stabilt, og derefter periodisk for at minimere risikoen for forhøjet blodtryk.
Chronic renal failure patients on erythropoietin should have their haemoglobin (the part of a red blood cell that carries oxygen) levels measured on a regular basis until a stable level is achieved, and periodically thereafter to minimise the risk of an increase in blood pressure.
