Kidney Health Tests in Virginia

Kidney health tests are blood tests that check how well your kidneys filter waste from your blood. They are often ordered during routine checkups or when a clinician suspects a kidney problem, such as from diabetes, high blood pressure, or certain medications.

What it measures

Creatinine — A waste product from muscle that healthy kidneys remove from blood.
eGFR (estimated glomerular filtration rate) — A calculated number that estimates how well your kidneys filter.
Blood urea nitrogen (BUN) — Another waste product that can rise when kidney function drops.
Electrolytes (sodium, potassium, bicarbonate) — Minerals your kidneys balance; abnormal levels can signal kidney issues.
Albumin or protein — A blood protein checked to help assess kidney and overall health.

Who it is for

A primary care clinician, nephrologist, or other healthcare provider typically orders these tests. They may be ordered for routine screening, monitoring a chronic condition, or evaluating symptoms like swelling or fatigue.

Preparation

Fasting is usually not required for kidney blood tests, but your clinician may ask you to fast if other tests are done at the same time. Tell your provider about all medications and supplements you take, as some can affect results.

Results and what they mean

Results are reported as numbers with reference ranges, and your clinician interprets them alongside your health history, symptoms, and other tests. A single abnormal value does not always mean kidney disease. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
