Introduction
Many people search for renal failure levels after receiving abnormal kidney function test results or being diagnosed with chronic kidney disease (CKD). Understanding the level of kidney function helps patients know how advanced the disease is and what treatment may be required.
Doctors do not determine kidney failure based on creatinine alone. Instead, they evaluate several factors, including the Estimated Glomerular Filtration Rate (eGFR), serum creatinine, urine tests, symptoms, blood pressure, and overall health.
Early diagnosis is important because kidney disease often progresses silently. Timely treatment can slow disease progression, reduce complications, and help preserve remaining kidney function.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, personalized treatment plans, dialysis planning, kidney transplant evaluation, and long-term kidney care.
What Is Renal Failure?
Renal failure occurs when the kidneys lose their ability to adequately:
-
Filter waste products
-
Remove excess fluid
-
Balance electrolytes
-
Regulate blood pressure
-
Produce hormones that support red blood cell production
Kidney failure may develop suddenly (Acute Kidney Injury) or gradually (Chronic Kidney Disease progressing to End-Stage Kidney Disease).
How Are Renal Failure Levels Measured?
Kidney function is primarily assessed using:
-
Estimated Glomerular Filtration Rate (eGFR)
-
Serum Creatinine
-
Urine Protein Tests
-
Blood Pressure
-
Kidney Imaging
-
Overall clinical condition
The eGFR is the main measurement used to classify chronic kidney disease into stages.
Chronic Kidney Disease Stages (Renal Failure Levels)
Stage 1 (Normal or High Kidney Function)
eGFR: 90 mL/min/1.73 m² or higher
Kidney damage may already be present despite normal filtration.
Treatment focuses on:
-
Identifying the underlying cause
-
Controlling diabetes
-
Managing blood pressure
-
Preventing further kidney damage
Stage 2 (Mild Reduction)
eGFR: 60–89 mL/min/1.73 m²
Kidney function is slightly reduced.
Many patients have no symptoms.
Regular monitoring is recommended.
Stage 3 (Moderate Reduction)
eGFR: 30–59 mL/min/1.73 m²
Stage 3 is divided into:
-
Stage 3A
-
Stage 3B
Symptoms may begin to appear, including:
-
Fatigue
-
Swelling
-
High blood pressure
-
Changes in urination
Early nephrology care becomes especially important.
Stage 4 (Severe Reduction)
eGFR: 15–29 mL/min/1.73 m²
Kidney function is significantly reduced.
Patients require close monitoring and preparation for possible kidney replacement therapy.
Treatment focuses on:
-
Preserving remaining kidney function
-
Managing complications
-
Planning for dialysis if necessary
-
Evaluating eligibility for kidney transplantation
Stage 5 (Kidney Failure)
eGFR: Below 15 mL/min/1.73 m²
Stage 5 is also called:
-
End-Stage Kidney Disease (ESKD)
-
End-Stage Renal Disease (ESRD)
Patients may require:
-
Hemodialysis
-
Peritoneal Dialysis
-
Kidney Transplantation
Treatment decisions are individualized according to each patient's condition.
Symptoms of Advanced Renal Failure
As kidney function declines, symptoms may include:
-
Severe fatigue
-
Swelling of the legs, feet, hands, or face
-
Reduced urine output
-
Frequent urination at night
-
Loss of appetite
-
Nausea and vomiting
-
Persistent itching
-
Muscle cramps
-
Shortness of breath
-
Difficulty concentrating
-
High blood pressure
Some patients may have very few symptoms until kidney disease becomes advanced.
Common Causes of Renal Failure
Kidney failure may result from:
-
Diabetes
-
High blood pressure
-
Glomerulonephritis
-
Polycystic Kidney Disease
-
Autoimmune diseases
-
Recurrent kidney infections
-
Urinary obstruction
-
Acute Kidney Injury
Treating the underlying condition is essential.

Medical History and Physical Examination
The doctor reviews:
-
Symptoms
-
Medical history
-
Blood pressure
-
Diabetes history
-
Current medications
-
Family history
Blood Tests
Important investigations include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-

Hemoglobin
These tests help assess kidney function and identify complications.
Urine Tests
Urine investigations may include:
-
Routine Urinalysis
-
Protein Estimation
-
Urine Microscopy
-
Urine Culture when indicated
These tests help detect kidney damage and infection.
Imaging Studies
Depending on the patient's condition, investigations may include:
-
Kidney Ultrasound
-
CT Scan
-
MRI when clinically indicated
Additional Testing
In selected patients, additional investigations may include:
-
Kidney biopsy
-
Autoimmune testing
-
Specialized laboratory investigations

Treatment depends on the stage of kidney disease.
Early Stages
Management focuses on:
-
Blood pressure control
-
Diabetes management
-

-
Lifestyle modification
-
Medications to slow disease progression
Advanced Stages
Patients may require:
-
Anemia treatment
-
Electrolyte management
-
Fluid management
-

Frequently Asked Questions (FAQs)
Is creatinine alone enough to determine renal failure levels?
No. Doctors evaluate eGFR, creatinine, urine tests, symptoms, blood pressure, and overall health before determining the stage of kidney disease.
Does Stage 5 kidney disease always require dialysis?
Many patients with Stage 5 kidney disease require dialysis or kidney transplantation, but treatment decisions are individualized according to symptoms, kidney function, and overall health.
Can kidney disease progression be slowed?
Yes. Early diagnosis, blood pressure control, diabetes management, medications, dietary changes, and regular nephrology follow-up can significantly slow disease progression.
