Chronic nephritis is a glomerular disease characterized clinically by hematuria, proteinuria, edema, and hypertension. The condition persists over time with slow progression, accompanied by impaired kidney function or not. Creatinine is a metabolic waste product of the body; as long as one is alive, various metabolic wastes are produced. If serum creatinine levels rise, this indicates a decline in the kidney's ability to excrete metabolic waste, which is known as renal failure.
