Kidney Health Tests
Kidney Health Tests can be ordered without a referral, and this guide covers what to expect. Kidney health tests help assess how well your kidneys are functioning. These tests can provide important information about your overall kidney wellness.
What this test is
This panel is a group of laboratory tests that evaluate kidney function and detect potential issues. It measures various substances in your blood and urine to understand how efficiently your kidneys are filtering waste products.
What it measures
- Blood Urea Nitrogen (BUN) — reflects kidney function and hydration status
- Creatinine — a waste product filtered by the kidneys
- Estimated Glomerular Filtration Rate (eGFR) — calculates kidney filtration capacity
- Albumin-to-Creatinine Ratio (ACR) — checks for protein in the urine, an early sign of kidney damage
- Electrolytes (Sodium, Potassium, Chloride, CO2) — assess fluid and electrolyte balance
What the test involves
A sample is typically collected through a standard blood draw from a vein in your arm. In some cases, a urine sample may also be required.
Why it is often ordered
Clinicians often order kidney health tests to monitor for or diagnose kidney disease, especially in individuals with risk factors like diabetes or high blood pressure. They can also be used to track the effectiveness of treatments for kidney conditions.
Preparation
Please follow any specific preparation instructions provided by the laboratory where you will have your sample collected. This may include fasting or avoiding certain foods or medications.
How results are reported
Your results will be provided to you, typically within a few business days. It is important to note that reference ranges, which indicate what is considered normal, can vary between different laboratories.

Frequently asked questions
What are the signs of kidney problems?
Early kidney disease often has no symptoms. As it progresses, symptoms can include fatigue, swelling in the legs or ankles, changes in urination, and skin itching. Regular testing is key for early detection.
Can kidney function be improved?
Depending on the cause and stage of kidney issues, function can sometimes be improved or its decline slowed. Lifestyle changes, medication, and managing underlying conditions like diabetes and high blood pressure are crucial.
How often should I get kidney tests?
The frequency of kidney testing depends on your individual health status and risk factors. Your healthcare provider will recommend a testing schedule tailored to your needs.
What happens if my kidney test results are abnormal?
Abnormal results indicate that further investigation is needed. Your healthcare provider will discuss the findings with you, explain what they mean, and recommend appropriate next steps, which may include additional tests or treatment.
