Creatinine with eGFR (18 Years & Above)

The Creatinine with eGFR (18 Years & Above) test is an important component of kidney function assessments as it provides useful information about the efficiency of kidney performance. Creatinine is a waste product produced from the normal breakdown of muscles. It is filtered out from the blood by the kidneys and eliminated via the urine. The estimated glomerular filtration rate (eGFR) measures how well the kidneys are filtering out the waste products from the body per minute, based on your age and gender.

The Creatinine with eGFR (18 Years & Above) test provides a more comprehensive assessment of kidney function and is a more accurate way to measure kidney health than a standalone creatinine test. This test is often performed when individuals experience symptoms of kidney dysfunction such as urinary changes, swelling in the feet, loss of appetite, and fatigue. Also, testing for serum creatinine and eGFR is critical for individuals who have chronic kidney disease or are at risk of developing it. It helps doctors to stage the level of kidney disease and decide on the appropriate management or treatment. It is also used to monitor individuals who have been diagnosed with other conditions that could affect the kidneys, such as diabetes or high blood pressure. Thus regular monitoring of creatine along with eGFR is essential for identifying and managing kidney-related diseases.

Usually, no special preparation is needed before undergoing the Creatinine with eGFR (18 Years & Above) test. But, it is still advised to follow your doctor's instructions closely. Additionally, it is important to tell your doctor about any medications and supplements you are taking as certain medications can temporarily affect your test results. 

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. Narrate your complete medical history to help them correlate your clinical and laboratory findings. The results will help the doctor determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage your kidney health and formulate your overall treatment plan.
