Diagnosis

  1. Diagnosis

Kidney function can be assessed through blood and urinalysis. Certain markers, such as blood creatinine levels and glomerular filtration rate (GFR, ml/min), provide essential criteria to define and distinguish the 5 stages of CKD.

According to the residual kidney function, measured by GFR, the disorder is classified into five stages (I-V). The advanced stages, or end stage renal disease (ESRD) require the start of renal replacement therapy (RRT). RRT consists of dialysis therapy and/or kidney transplantation. Together with the level of persistent albuminuria, prognosis of CKD can be made (table).

Comorbidities

In CKD patients the risk for cardiovascular mortality or a cardiovascular event is significantly increased compared to the general population.
