Blood Tests (Kidney Function Tests – KFT)
- Estimated GFR (eGFR): Estimated Glomerular Filtration Rate (eGFR) is a test that shows how well your kidneys are cleaning waste from your blood. It is calculated using your blood creatinine level along with your age and sex. An elevated eGFR (about 90 or higher) indicates good kidney function, whereas lower readings indicate decreased kidney function. If the eGFR remains below 60 for several months, it may indicate a condition known as chronic kidney disease. However, very low levels (less than 15) can mean kidney failure. Doctors use this test along with other reports to understand kidney health, and if it is low, managing blood pressure, blood sugar, and healthy lifestyle habits becomes important.
- Creatinine test: Creatinine is a waste product that develops from the digestion of protein intake from the diet and muscle tissue breakdown. It is removed from the blood through the kidney. An increase in creatinine concentration can be a sign of kidney disease. It is the endogenous marker for the assessment of GFR that involves the collection of urine over a 24-hour period or for 5 to 8 hours. It is calculated by using the formula. C = (U x V) / P.
- Blood urea nitrogen test (BUN): It is an end product of protein metabolism and the urea cycle. It's mostly formed in the liver. Nearly 85% of the urea is eliminated through the kidneys. Any abnormality in the kidney function results in an increase in serum urea levels.
- BUN–creatinine ratio: This test is used to differentiate prerenal from renal causes based on increased blood nitrogen levels. The ratio is close to 20:1 in the case of prerenal disease (poor blood perfusion to nephrons, leading to a decrease in GFR) and 10:1 if it is an intrinsic renal disease (conditions that affect glomerulus or tubule). Upper gastrointestinal bleeding can be associated with a high BUN to creatinine ratio (>30:1).
- Cystatin C test: It is a low molecular weight protein that functions as a protease inhibitor, which is produced by the body's nucleated cells, formed at a constant rate and filtered out by the kidneys. Serum cystatin C levels will be increased with decrease in GFR rate. Cystatin C was measured both in urine and serum samples.
- Electrolyte panel: Electrolyte tests help to measure levels of sodium, potassium, calcium, phosphate, and bicarbonate in the blood. Kidney disease changes the balance of these minerals due to impaired filtration. Abnormal levels may cause muscle weakness, heart rhythm disturbances, and bone problems, making these tests vital for disease assessment and ongoing management.
Urine Tests
- Urinalysis: It is a test that examines the visual, chemical, and microscopic aspects of urine and detects various compounds passing through the kidneys.
- Visual: The healthcare provider examines the colour (pale, dark yellow, etc.) and appearance (cloudy or clear) of urine through the naked eye.
- Chemical: It can be analysed with the help of strips known as a dipstick, which consists of chemical pads that change colour when in contact with a urine sample. The degree of colour change in the dipstick estimates the presence of chemical substances in the urine. A light colour represents the trace or small amounts of substance in the provided urine sample, while a deep colour represents large amounts. The dipstick test detects proteins, ketones, glucose, bilirubin, nitrites, and leukocyte esterase concentrations in the urine in addition to urine pH and specific gravity.
- Microscopic: This test is used to examine the presence of substances such as mucus, urinary casts, cells and their fragments, bacteria, yeast, parasites, and crystals. In addition, the presence of red blood cells(RBC), white blood cells (WBC), epithelial cells, and urinary casts can also be detected in the urine sample.
Albuminuria test: Albuminuria is defined as the abnormal presence of albumin in the urine. It is the independent marker for cardiovascular disease and incipient nephropathy in diabetics, in addition to being a marker for chronic renal impairment. It may be measured in a 24-hour urine sample or early morning sample. The presence of albumin in the urine on both occasions (early morning and 24 hours) with an exclusion of urinary tract infection can indicate the presence of kidney dysfunction. The presence of albuminuria for more than three months indicates chronic kidney disease.
Imaging Tests
- Kidney ultrasound: It is a non-invasive diagnostic exam that visualizes the blood flow, shape, size and location of the kidneys. The urologist will be placing an ultrasound transducer on the skin that emits high-frequency ultrasound waves that move through the kidney. These ultrasound waves produce images of the kidney that are presented to the computer. This test is used to diagnose the presence of cysts, obstructions, abscesses, stones and infections of the kidney. In addition, it is indicated after a kidney transplant to evaluate the transplanted kidney.
- Computed tomography scan (Kidney CT scan): It is also known as renal scintigraphy, where the kidneys can be visualized with the help of nuclear radioactive material (radioisotope) that will be inserted into the vein (hand or arm). The images of the kidney can be created when the scanner detects the gamma rays released from the radioisotope. This test can be used to examine the size, shape and structure of the kidney. In addition, it is used to identify and evaluate the reduced flow of blood to the kidneys, high blood pressure in real arteries, kidney diseases, success or rejection of kidney transplant, renal abscesses, tumours, kidney inflammation due to infections, urine backflow from the bladder to the kidney and kidney failure.
- Renal Doppler ultrasound: Renal Doppler ultrasound evaluates blood flow to and within the kidneys. It is effective in detecting narrowing of renal arteries, reduced perfusion, and vascular causes of kidney dysfunction. This test supports the diagnosis of renovascular hypertension and helps assess transplant kidney circulation.
Kidney biopsy
A kidney biopsy is a diagnostic procedure that involves taking a small piece or sample of kidney tissue in order to view it under a microscope for indications of kidney damage or injury. In addition to this, kidney biopsy is indicated in the development of treatment plans based on the patient's condition to determine the kidney disease progression, extent of kidney damage, evaluation of prescribed treatment for kidney disease, and monitoring of transplanted kidney, which is failed to perform normal functions.
Genetic Testing
Genetic testing: Genetic testing is used when inherited renal disorders are suspected, particularly in patients with early-onset disease or family history. These tests help to identify conditions such as polycystic kidney disease and guide prognosis, counselling, and treatment decisions.

Frequently Asked Questions (FAQs) on Nephrology Diagnostic Tests
What does a nephrologist diagnose?
A nephrologist diagnoses diseases that affect the kidneys and their function. These include chronic kidney disease, sudden kidney injury, kidney infections, inherited kidney disorders, and problems caused by diabetes or high blood pressure. A nephrologists also evaluate fluid balance, blood salt levels, and acid levels in the body, which are closely linked to kidney health. Diagnosis depends on symptoms, blood and urine tests, imaging studies, and sometimes kidney biopsy results.
What does GFR indicate in kidney diagnosis?
Glomerular filtration rate (GFR) indicates how well the kidneys filter waste and excess fluid from the blood. GFR is the best overall measure of kidney function. A lower GFR means reduced filtering ability and possible kidney damage. GFR values help classify the stage of kidney disease, monitor disease progression, and guide treatment decisions. It is usually estimated from a blood creatinine test, along with age and sex, rather than measured directly.
Can kidney disease be diagnosed with a blood test alone?
Kidney disease cannot usually be diagnosed using a blood test alone. Blood tests like creatinine and GFR show how well the kidneys are working, but they do not explain the cause of damage. Urine tests are needed to detect protein or blood loss, and imaging tests help assess kidney size and structure. A complete diagnosis also requires combining blood results with urine findings, medical history, and sometimes imaging or biopsy results.
What tests are commonly used to diagnose kidney disease?
Kidney disease is diagnosed using a combination of tests. Diagnostic tests, such as blood tests, measure creatinine and estimate GFR to assess kidney function. Urine tests help to detect protein, blood, or waste products that should not be present in large amounts. Imaging tests, such as ultrasound, examine kidney size and structure. In selected cases, a kidney biopsy is used to identify the exact cause of damage. Using multiple tests improves diagnostic accuracy.
What is proteinuria, and why is it important?
Proteinuria refers to the presence of excess protein in the urine. It occurs when the kidney filters are damaged and allow protein to leak into the urine. Proteinuria is important because it is an early sign of kidney disease, even when blood tests show normal. Higher protein levels are linked to faster kidney function loss and increased risk of heart disease.
When is a kidney ultrasound advised?
Kidney ultrasound is advised when blood or urine tests suggest kidney disease or blockage. It is frequently used to check kidney size, shape, and blood flow, and to detect stones, cysts, or swelling. Ultrasound is also suggested when there is unexplained pain, repeated urinary tract infections, or a sudden decline in renal function. It is safe, painless, and does not use radiation, making it suitable for initial evaluation.
What is a kidney biopsy, and when is it needed?
A kidney biopsy is a medical test in which a very small piece of kidney tissue is removed using a thin needle and evaluated under a microscope. It helps to identify the exact cause of kidney damage. It is needed when blood and urine tests cannot explain worsening kidney function, heavy protein loss in urine, or unclear kidney inflammation. The results help guide treatment and predict disease outcome.
What symptoms prompt kidney testing?
Kidney testing is prompted by symptoms that suggest reduced kidney function. The common warning signs include swelling of the feet or face, reduced or foamy urine, fatigue, nausea, poor appetite, and high blood pressure. Some people may also have back pain or repeated urinary infections. Because early kidney disease often has no symptoms, testing is also advised when risk factors such as diabetes, hypertension, or family history are present.
Are kidney tests different for children?
Kidney tests for children are similar to those for adults but adjusted for age, size, and growth. Normal kidney function values differ between children and adults. Blood creatinine levels are lower in children because of smaller muscle mass, so special formulas are used to estimate kidney function. These adjustments ensure accurate diagnosis and avoid misinterpretation of results.
Why is repeated testing required in kidney disease?
Repeated testing is required because kidney disease can develop slowly and change over time. A single abnormal result may be temporary, caused by dehydration, infection, or medication use. Repeating tests confirms whether kidney damage is continuous. These tests also help monitor disease progression, treatment response, and complications.
Can routine health checkups detect kidney disease?
Routine health checkups can detect early kidney disease. Simple blood tests for creatinine and estimated GFR, as well as urine protein or blood analysis, can detect renal problems before symptoms appear. Patients with diabetes, hypertension, obesity, or advanced age benefit from regular screening. Early detection through routine testing allows for prompt treatment, which can assist to limit disease development and prevent complications.
