A Kidney Function Test (KFT) checks how efficiently your kidneys are filtering waste from the blood. It measures markers like creatinine, urea/BUN, uric acid and electrolytes, and is one of the standard tests used to detect early kidney damage - often before symptoms appear.
It can help your doctor assess
Acute kidney injury, chronic kidney disease (CKD) and its stage, dehydration, and electrolyte imbalances.
This test may be considered for:
Whether this test is right for you depends on your symptoms, medical history and the reason for testing - your doctor can advise.
Blood urea/BUN, serum creatinine, eGFR (estimated glomerular filtration rate), uric acid, sodium, potassium, chloride, and calcium.
Serum Creatinine
Filtration Markers
A waste product from muscle metabolism, filtered out by the kidneys. Rising creatinine is the key marker of reduced kidney function.
eGFR
Filtration Markers
A calculated estimate of how well the kidneys are filtering blood, used to stage kidney disease.
Blood Urea/BUN
Filtration Markers
Another waste product cleared by the kidneys; rises with reduced kidney function or dehydration.
Uric Acid
Electrolytes & Other Markers
Can build up with reduced kidney clearance, and is separately linked to gout.
Sodium, Potassium, Chloride
Electrolytes & Other Markers
Electrolytes the kidneys help regulate; imbalances can affect heart rhythm and muscle function.
How to read your result
Your report should be read using the reference interval, unit and method shown by the performing laboratory. A result outside a reference interval does not automatically establish a diagnosis, and a result inside the interval does not rule out every health problem. Clinical interpretation depends on symptoms, history and other findings.
| Marker | Result | What it may be associated with |
|---|---|---|
| Creatinine | High | May indicate reduced kidney function - can be acute (dehydration, infection) or chronic. |
| eGFR | Low | Indicates reduced kidney filtration capacity; used to stage chronic kidney disease. |
| Potassium | High | Can be dangerous for heart rhythm - often linked with reduced kidney function or certain medicines. |
If a result is outside the range
If the Kidney Function Test is reported as high, low, positive, negative or otherwise outside the laboratory's stated interval, the meaning depends on the specific test and the reason it was ordered. Your clinician may consider repeat testing, related investigations or other clinical information before deciding what the result means.
Limitations of this test
A single abnormal reading can reflect a temporary factor rather than true kidney disease - doctors typically confirm with a repeat test and consider trends over time rather than one isolated value.
An abnormal result does not by itself mean you have a particular disease. Your doctor interprets results together with your symptoms, history and other tests.
| Parameter | Reference range | Unit |
|---|---|---|
| Serum Creatinine | 0.7 - 1.3 (men), 0.6 - 1.1 (women) | mg/dL |
| Blood Urea | 15 - 40 | mg/dL |
| eGFR | Above 90 | mL/min/1.73m² |
| Uric Acid | 3.5 - 7.2 (men), 2.6 - 6.0 (women) | mg/dL |
| Potassium | 3.5 - 5.0 | mEq/L |
Typical adult ranges for guidance. Reference intervals vary with the laboratory method, age and sex - always read your result against the range printed on your own report.

Prepare
Follow the preparation steps above for this test.
Sample collection
A trained phlebotomist collects the sample at your home - no extra charge.
Laboratory processing
Your sample is processed in our laboratory and reviewed by a pathologist.
Report
Your report is shared on WhatsApp and email, usually within 24 hours.
For a blood-based test, a small blood sample is collected by a trained healthcare professional, usually from a vein in the arm. The collection normally takes only a few minutes; mild temporary discomfort or bruising can occur at the puncture site.
High protein intake, intense exercise, dehydration and certain medicines (e.g. NSAIDs) can temporarily raise creatinine and urea without true kidney damage.
Laboratory results are interpreted together with your symptoms, medical history and other investigations. If your results are significantly abnormal, or you have symptoms that worry you, discuss them with a qualified doctor promptly.

Fasting is not strictly required, though your doctor may ask you to fast if it’s combined with other fasting tests like blood sugar.
High creatinine suggests your kidneys aren’t filtering waste as efficiently as they should. It can be temporary (dehydration, high protein intake, intense exercise) or reflect ongoing kidney disease - your doctor will look at the trend and other values like eGFR.
Diabetes is one of the leading causes of chronic kidney disease, and early kidney damage often has no symptoms - regular KFT screening (usually annually) helps catch problems early when they’re most manageable.
eGFR estimates how much blood your kidneys filter per minute. It’s used to stage kidney disease from mild reduction to kidney failure, and is often more informative than creatinine alone.
Raised uric acid is associated with gout, but the diagnosis needs a clinical picture of joint pain/swelling too - a raised level alone isn’t a diagnosis on its own.
Annually for people with diabetes, high blood pressure or a family history of kidney disease; otherwise as advised by your doctor based on your individual risk.

The Kidney Function Test can provide important information, but laboratory results are generally interpreted together with symptoms, medical history, examination and other investigations. A single result should not be treated as a diagnosis without clinical context.
Some medicines, supplements, food, exercise and other pre-test factors can affect particular laboratory results. Tell the healthcare professional about medicines and supplements you take, and do not stop prescribed medicines unless your clinician tells you to.
