eGFR Test

The estimated glomerular filtration rate (eGFR) test is a routine part of a comprehensive blood panel that helps assess how well your kidneys are functioning. It estimates how efficiently your kidneys are filtering waste from your blood, which is a vital indicator of overall kidney health. An eGFR test is especially useful for detecting early signs of kidney disease and monitoring existing conditions.

Why Would a Doctor Recommend an eGFR test?

Your doctor may suggest an eGFR test if you have risk factors for kidney problems, such as high blood pressure, diabetes or a family history of kidney disease. It’s also a useful test to check kidney function before prescribing medications that can affect the kidneys. As part of a wider blood test, it offers a quick and accurate insight into how well your kidneys are performing.

What Does a Low eGFR Mean?

A low eGFR result can indicate that your kidneys are not filtering blood as efficiently as they should. Depending on the value, it may suggest mild, moderate or severe kidney impairment. Early-stage kidney disease often has no symptoms, so a low eGFR reading might be the first sign of an issue that needs further investigation.

How Often Should eGFR Be Tested?

If you’re at risk of kidney disease, or have already been diagnosed with a kidney-related condition, your doctor may recommend regular eGFR testing. This could range from once a year to more frequent monitoring, depending on your individual health profile and any ongoing treatments.
