Clinical situation where is eGFR results may be unreliable and/or misleading

Clinical situation where is eGFR results may be unreliable and/or misleading:

• Acute changes in kidney function (e.g. acute kidney injury)
• People on dialysis
• Recent consumption of cooked meat (consider re-assesment when the individual has fasted or specifically avoided a cooked meat meal within 4 hours of blood sampling)
• Exceptional dietary intake  (e.g. vegetarian diet, high protein diet, creatine supplements)
• Extremes of body size
• Diseases of skeletal muscle, paraplegia, or amputees (may  overestimate eGFR)
• High muscle mass (may under estimate eGFR)
• Severe liver disease present
• eGFR values above 90 ml/min/1.73m2
• Drugs interacting with creatine excretion (e.g. fenofibrate, trimetroprim)
• Pregnancy
