Your eGFR (estimated glomerular filtration rate) is one of the most useful numbers for understanding how well your kidneys are filtering waste from your blood. In general, a higher eGFR suggests better kidney filtration, while a persistently low eGFR may indicate reduced kidney function. However, one eGFR result alone does not diagnose chronic kidney disease. Doctors interpret eGFR together with creatinine, urine albumin or protein, previous reports, age, medical history and conditions such as diabetes or high blood pressure. Patients with repeatedly abnormal kidney-function reports can consult a nephrologist in Navi Mumbai for appropriate evaluation. What Is an eGFR Test? eGFR stands for estimated glomerular filtration rate. It estimates how much blood the kidneys filter over a period of time and is commonly reported as part of a kidney function blood test. The value is usually calculated using the amount of creatinine in your blood along with other relevant factors. Creatinine is a waste product generated from normal muscle activity. Because the kidneys remove creatinine from the bloodstream, changes in creatinine can influence the calculated eGFR. Why Is eGFR Important for Kidney Health? Kidney disease can develop without obvious symptoms, particularly during its earlier stages. An eGFR test can therefore help identify reduced kidney filtration even when a person feels well. The test is particularly important for people who have diabetes, hypertension, heart disease, abnormal creatinine or a known kidney condition. If kidney function remains abnormal, further evaluation for acute or chronic kidney disease may be required Does an eGFR Below 60 Mean Kidney Disease? Understanding Low eGFR When to Consult a Kidney Specialist An eGFR below 60 can indicate reduced kidney filtration, particularly when it remains below this level over repeated tests for three months or longer. Your doctor may review previous creatinine and eGFR results to determine whether the change is persistent or temporary. A temporary reduction may sometimes occur during acute illness, dehydration or other situations affecting kidney function. This is why doctors do not normally interpret one laboratory result without considering the patient’s overall clinical condition. Is an eGFR Above 60 Always Normal? Not necessarily. Someone can have an eGFR above 60 and still have signs of kidney damage, such as persistent albumin or protein in the urine. This is why kidney assessment often includes both eGFR and a urine albumin-to-creatinine ratio (UACR). A UACR above 30 mg/g may indicate albuminuria and requires interpretation by a healthcare professional. How Are Creatinine and eGFR Connected? Creatinine and eGFR are closely related. When kidney filtration decreases, creatinine may rise and the calculated eGFR may fall. However, serum creatinine can also be influenced by factors such as muscle mass, diet and certain clinical conditions. For this reason, eGFR generally provides more useful context than looking at creatinine alone, although neither number should be interpreted in isolation What Can Affect an eGFR Result? Several factors can influence the accuracy or interpretation of an eGFR result. These may include changes in creatinine, unusual muscle mass, recent illness, diet, pregnancy, some medicines and rapidly changing kidney function. Because eGFR is an estimate rather than a direct measurement, doctors may sometimes use additional tests when the result does not match the patient’s overall clinical picture. Cystatin C can also be used in some circumstances to improve estimation of GFR Why Are Diabetes and High Blood Pressure Important? Diabetes and high blood pressure are important causes and risk factors for chronic kidney disease. People with diabetes should have their kidney health monitored because kidney damage can develop gradually. Patients who have diabetes together with abnormal eGFR or urine protein can read more about diabetes and kidney disease. Similarly, persistent or difficult-to-control hypertension may require evaluation because blood pressure and kidney health are closely connected. What Should You Do If Your eGFR Is Low? Do not panic based on a single laboratory result. Your doctor may first compare the result with previous reports and may recommend repeating creatinine and eGFR. Further evaluation may include urine routine examination, UACR, blood pressure assessment, electrolytes, blood sugar testing and kidney imaging depending on the clinical situation. The goal is to understand why the eGFR is low, whether the change is temporary or persistent and whether kidney damage is present. Can a Low eGFR Improve? A reduced eGFR may improve when it is caused by a reversible problem such as dehydration or certain acute illnesses. However, chronic kidney disease usually requires long-term monitoring and management aimed at slowing further loss of kidney function. Patients should not attempt to increase eGFR through excessive water intake, supplements or unverified kidney-cleansing remedies. Treatment should address the underlying cause and be guided by the treating doctor or nephrologist. When Should You See a Nephrologist? Consider seeing a kidney specialist if your eGFR remains below normal on repeated tests, continues to decline, or occurs with high creatinine, protein or blood in urine, swelling, reduced urine output, diabetes or uncontrolled hypertension. A rapid decline in kidney function, very low urine output, severe breathing difficulty, confusion or significant swelling may need urgent medical evaluation rather than waiting for a routine appointment. eGFR Evaluation by a Nephrologist in Navi Mumbai and Vashi Patients with abnormal kidney function reports can learn more about Dr. Jyoti Bansode and her nephrology services. Kidney-function evaluation can help determine whether a reduced eGFR is related to an acute problem, chronic kidney disease, diabetes, hypertension or another kidney condition.

The practice website also lists consultation options for patients from Navi Mumbai and surrounding areas. Patients searching online for the best nephrologist in Navi Mumbai should consider a doctor’s qualifications, nephrology experience, hospital affiliations and experience managing the particular kidney problem rather than relying only on promotional claims. Frequently Asked Questions What is a normal eGFR? An eGFR of 90 or above generally represents normal or high filtration in adults, although kidney health should also be assessed using urine tests and other clinical information.
