1. Early detection of renal disease is important through screening methods like urine and blood tests as most early renal failures are asymptomatic. 2. High risk groups for renal disease include those with diabetes, hypertension, cardiovascular disease, urinary tract infections, and a family history of kidney disease. These groups should be regularly screened. 3. Screening allows for early treatment and measures to slow disease progression, reducing complications and allowing time for education and vascular access planning for renal replacement therapy if needed. Benefits of early detection include better outcomes.
