Urea and creatinine are waste products produced by the body and normally filtered out by the kidneys. The estimated glomerular filtration rate (eGFR) is a calculated measurement that gives an indication of how well the kidneys are filtering waste from the blood. Monitoring these markers is important because it helps doctors and patients detect changes in kidney function and potential problems early on. If kidney function is impaired these markers may be elevated and indicate the need for further evaluation and treatment.

Normal results on a kidney function test indicate that the kidneys are functioning normally. This is important information for anyone who is concerned about their kidney health. While good results are a positive sign it's important to remember that other health issues can still arise, even if the kidneys are functioning normally. If you experience any symptoms it's important to speak with a healthcare provider.

Lifestyle changes such as maintaining a healthy diet, exercising regularly, and managing any underlying health conditions can help improve kidney function and maintain healthy marker levels. In addition, limiting exposure to certain substances, such as alcohol and certain medications, can also help protect kidney health. Speaking with a healthcare provider about any concerns or questions is important for overall health and well-being.

Patients who check their kidney function may also wish to check their Liver Function and Cholesterol, HbA1c and Vitamin D levels.
