Renal insufficiency: No azotaemia. Decreased GFR; poor concentrating ability.

STAGE 2

125-179 1.4-2.0

Early renal failure: Mild azotaemia. Mal-adaptions can lead to hyperparathyroidism and hypokalaemia.

180-439 2.1-5.0

Uraemic renal failure: Moderate to severe azotaemia. Systemic signs present: e.g. bone pain, uraemic gastritis, anaemia, metabolic acidosis.
