Estimated Glomerular Filtration Rate (eGFR) with Creatinine and Cystatin C

The Estimated Glomerular Filtration Rate (eGFR) with Creatinine and Cystatin C test contains 1 test with 5 biomarkers .

Evaluate Kidney Function with the eGFR Test Using Creatinine and Cystatin C

The Estimated Glomerular Filtration Rate (eGFR) with Creatinine and Cystatin C test is designed to help assess kidney function by estimating how well your kidneys filter waste from your blood. By using both creatinine and cystatin C, this test provides a more complete evaluation of glomerular filtration rate (GFR) and may improve accuracy compared to creatinine-based testing alone.

This test can be useful for detecting early changes in kidney health, monitoring chronic kidney disease (CKD), and providing additional insight when traditional kidney function markers may be less reliable.

What Is the eGFR with Creatinine and Cystatin C Test?

The eGFR with Creatinine and Cystatin C test measures two important biomarkers that help estimate how efficiently your kidneys are working:

Creatinine

Creatinine is a waste product produced by normal muscle activity. Healthy kidneys remove creatinine from the blood. Elevated creatinine levels may suggest reduced kidney function, but creatinine can also be influenced by muscle mass, age, sex, and diet.

Cystatin C

Cystatin C is a protein made by cells throughout the body and filtered by the kidneys. Because cystatin C is generally less affected by muscle mass, it can provide additional value when evaluating renal function.

Estimated Glomerular Filtration Rate (eGFR)

Estimated glomerular filtration rate (eGFR) is a calculation used to estimate how much blood your kidneys filter each minute. Combining creatinine and cystatin C may provide a more accurate picture of kidney filtration, especially in people where creatinine alone may not tell the full story.

Why Order an eGFR Test with Creatinine and Cystatin C?

The eGFR test with creatinine and cystatin C may help:

• Assess overall kidney function

• Detect early signs of chronic kidney disease

• Monitor known kidney conditions

• Clarify kidney function when creatinine alone may be less accurate

• Support medication management when dosing depends on kidney health

• Provide a more comprehensive renal health assessment

This test is often considered for people with risk factors for kidney disease or those who want a more advanced evaluation of kidney filtration.

Who Should Consider This Kidney Function Test?

You may consider the Estimated Glomerular Filtration Rate (eGFR) with Creatinine and Cystatin C test if you:

• Have diabetes

• Have high blood pressure

• Have a family history of kidney disease

• Have had abnormal kidney lab results

• Are monitoring chronic kidney disease

• Are older than 60

• Have unusually low or high muscle mass

• Take medications that may affect kidney function

• Want a more complete picture of your kidney health

Symptoms and Risk Factors of Reduced Kidney Function

Kidney disease may develop without obvious symptoms in the early stages. When symptoms do occur, they may include:

• Swelling in the feet, ankles, or hands

• Fatigue

• Weakness

• Changes in urination

• Foamy urine

• Nausea

• Loss of appetite

• Difficulty concentrating

• High blood pressure

Common risk factors for reduced glomerular filtration rate and kidney disease include:

• Diabetes

• High blood pressure

• Obesity

• Cardiovascular disease

• Smoking

• Family history of kidney disease

What Do eGFR, Creatinine, and Cystatin C Results Mean?

Results from the eGFR with creatinine and cystatin C test can help show whether kidney function is normal or reduced. A lower eGFR may indicate impaired kidney filtration and should be interpreted along with your overall health history and other laboratory findings.

Using both creatinine and cystatin C may improve confidence in the estimated result and help reduce the limitations of relying on creatinine alone.
