Kidney Function Test

The Kidney Function Test, also known as renal function test, assesses various markers, including creatinine, blood urea nitrogen (BUN), and glomerular filtration rate (GFR). This test helps evaluate kidney health and function.

Who would benefit from this test?

Individuals with known or suspected kidney disease or dysfunction.

Patients with high blood pressure or diabetes, which can impact kidney function.

Individuals taking medications that may affect the kidneys.

People with a family history of kidney disease.

Individuals with symptoms of kidney-related issues, such as changes in urine output or swelling.

Why undertake this test?

To assess kidney function and detect kidney disease or dysfunction.

To monitor the progression of known kidney conditions.

To evaluate the effectiveness of kidney-related treatments or medications.

To assess overall kidney health in individuals with risk factors.

To guide lifestyle modifications and preventive measures for kidney health.

Test Type: Biochemistry

Results Estimated: 2 Working days.

A little more detail:

A kidney function test, often referred to as renal function tests, is a group of blood and urine tests used to evaluate how well the kidneys are working. These tests are essential for diagnosing kidney diseases, monitoring kidney health, and assessing the effectiveness of treatments.

Key components of kidney function tests typically include:

1. Serum Creatinine: This blood test measures the level of creatinine, a waste product produced by muscle metabolism. Elevated levels can indicate impaired kidney function.

2. Blood Urea Nitrogen (BUN): This test measures the amount of nitrogen in the blood that comes from urea, another waste product filtered by the kidneys. High BUN levels can suggest kidney dysfunction or dehydration.

3. Estimated Glomerular Filtration Rate (eGFR): This calculation estimates how well the kidneys filter blood, based on serum creatinine levels, age, gender, and race. An eGFR below 60 mL/min/1.73 m² may indicate chronic kidney disease.

4. Urinalysis: A urine test checks for the presence of proteins, blood, or other substances that may signal kidney problems.

5. Urine Creatinine Clearance: This test compares the creatinine level in urine to that in blood, providing a measure of kidney filtering ability.

These tests are crucial for early detection of kidney issues, enabling timely interventions and helping to prevent further complications. Regular kidney function testing is especially important for individuals with risk factors such as diabetes, high blood pressure, or a family history of kidney disease.
