About this service

The Estimated Glomerular Filtration Rate (EGFR) test is used to estimate the efficiency of the kidneys in filtering waste and fluids from the blood. This test is an important tool in evaluating kidney function and diagnosing related conditions, such as kidney failure and chronic kidney disease. The EGFR is calculated based on blood creatinine levels, along with other factors like age, gender, and race. The lower the EGFR value, the higher the likelihood of kidney dysfunction. The results of this test can guide treatment decisions and monitor the progress of patients with chronic kidney conditions. This test is valuable in comprehensive healthcare, as it helps doctors assess health risks and develop appropriate treatment plans to maintain kidney health.

Purpose Test

Kidney Function: Used to estimate the kidneys’ efficiency in filtering waste and fluids from the blood.
Diagnosis of Kidney Failure: Helps identify any issues in kidney function, such as acute or chronic kidney failure.
Assessment of Kidney Diseases: Assists in monitoring the progression of chronic diseases like kidney inflammation or diabetes.
Guiding Treatment Options: Results are used to provide therapeutic guidance, such as adjusting medication doses based on kidney function.
Monitoring Overall Health: Helps assess overall health, especially for individuals at risk, such as those with high blood pressure or diabetes.

Recommended groups

Individuals with Chronic Kidney Disease: To monitor kidney function and assess disease progression.
Diabetic Patients: As diabetes is a major cause of kidney failure.
Hypertensive Patients: To monitor the impact of high blood pressure on kidney function.
Individuals with a Family History of Kidney Disease: To evaluate potential risks.
Elderly Individuals: As the likelihood of kidney problems increases with age.
People Taking Medications Affecting the Kidneys: To monitor the impact of drugs on kidney function.
Individuals Experiencing Symptoms of Kidney Dysfunction: Such as swollen feet or changes in urine output.

Symptoms indicative

Swelling: Such as swelling in the feet or ankles, which may indicate fluid retention.
Changes in Urine Output: Either increased or decreased urine volume.
Kidney Area Pain: Such as pain in the back or sides.
High Blood Pressure: Especially if it is unstable or difficult to control.
General Fatigue or Weakness: Persistent tiredness without a clear cause.
Nausea or Vomiting: These symptoms may be associated with kidney problems.
Loss of Appetite: Decreased desire to eat.

Normal Levels

Normal EGFR: Typically ranges between 90 and 120 mL/min/1.73 m² of body surface area.
EGFR Less Than 90: May indicate impaired kidney function and requires further evaluation.
EGFR Less Than 60: Considered a sign of chronic kidney disease and warrants ongoing monitoring and medical care.
EGFR Less Than 15: Indicates possible acute or end-stage kidney failure, which may require treatments such as dialysis or kidney transplantation.
