What is a normal eGFR?

A normal eGFR is typically 90 mL/min/1.73m² or higher, indicating healthy kidney function. Values between 60–89 may still be normal depending on age, but should be monitored.

How often should eGFR be tested?

Healthy individuals can test it during routine checkups. People with conditions like diabetes, high blood pressure, or kidney risk should test at least once a year or as advised by their doctor.

Can eGFR detect kidney disease early?

Yes, eGFR can identify kidney problems before symptoms appear, making it a key test for early detection and prevention of kidney disease progression.

Is there a free trial available for Flabs?

Yes, Flabs offers a free trial so labs can explore features like patient management, test tracking, and reporting before subscribing.

Can lab owners access Flabs on mobile phones?

Yes, Flabs is accessible on mobile devices, allowing lab owners and staff to manage operations anytime, anywhere.

eGFR and Its Clinical Importance

1. Early Detection of Kidney Disease

eGFR helps detect kidney damage at an early stage, often before visible symptoms appear. Early identification allows timely medical intervention and lifestyle changes. This plays a crucial role in slowing disease progression. It significantly improves long-term kidney health outcomes.

2. Monitoring Disease Progression

eGFR is essential for tracking how kidney function changes over time. Regular monitoring helps clinicians identify whether the condition is stable or worsening. It enables timely adjustments in treatment plans. This ensures better long-term disease management.

3. Treatment Decision Support

eGFR provides critical insights that help doctors choose the most effective treatment approach. It supports decisions related to medications, therapies, and specialist referrals. Accurate values ensure treatments are aligned with kidney function. This leads to safer and more personalized patient care.

4. Risk Assessment

Lower eGFR levels indicate a higher risk of complications such as cardiovascular disease and kidney failure. It helps clinicians evaluate overall patient health risks. Early risk identification allows preventive action. This improves patient prognosis and reduces complications.

5. Medication Safety

Many medications require dosage adjustments based on kidney function. eGFR ensures drugs are prescribed safely and effectively. Incorrect dosing can lead to toxicity or reduced effectiveness. Monitoring eGFR helps prevent such risks and enhances treatment safety.

6. Routine Health Screening

eGFR is a standard parameter in routine blood tests and health checkups. It provides early insights into kidney function even in asymptomatic individuals. Regular screening helps detect potential issues early. This supports preventive healthcare and long-term wellness.
