Kidney function test to identify kidney disease early.

Additional Information

One Australian dies every 25 minutes from kidney-related disease. You can lose up to 90% of kidney function before symptoms appear. Early detection with this test is crucial. The kidneys filter blood, control blood pressure, manage water balance, and activate Vitamin D. Early detection and management can reduce kidney function deterioration by up to 50%, potentially reversing damage.

Biomarkers Tested (18)

Sodium (mmol/L)

Sodium (Na) helps regulate water balance and nerve function. Abnormal levels can affect hydration status and blood pressure.

Potassium (mmol/L)

Potassium (K) is essential for nerve function and muscle contraction. Abnormal levels can affect heart and muscle function.

Chloride (mmol/L)

Chloride is important for maintaining fluid balance and for the proper functioning of the digestive system.

Bicarbonate (mmol/L)

Higher than normal levels suggests trouble maintaining pH balance either by failing to remove carbon dioxide or because of an electrolyte imbalance. Elevations may be seen with severe vomiting, chronic lung problems and some hormonal disorders. Low levels may be seen with chronic diarrhoea, diabetic ketoacidosis and kidney failure.

Urea (mmol/L)

A high concentration of this waste product can indicate dehydration or that your kidneys aren’t working properly.

Creatinine (mg/dL)

Creatinine (Cr) is a waste product from muscle metabolism, filtered by the kidneys. Elevated levels can indicate kidney dysfunction.

Urate (µmol/L)

If too much urate is produced or not enough is excreted, it can accumulate and lead to gout – an inflammation that occurs in joints.

Estimated Glomerular Filtration Rate (eGFR) (mL/min/1.73m²)

Measures how well kidneys filter blood wastes; best overall measure of kidney function.

Urine pH (pH units)

Kidney stones tend to form in a highly acidic or alkaline environment and cause pain as they prevent urine from passing. The urine pH level test can also be an indicator of urinary tract infection.

Urine Protein (mg/dL or g/24h)

Albumin in the urine can be temporary and harmless, caused by stresses such as fever or exercise, but it can also be a sign of early kidney disease.

Urine Glucose (mg/dL or g/24h)

A urine glucose test is often performed to check for diabetes. In some cases, a urine glucose test may also be done to check for kidney problems or a urinary tract infection.

Urine Blood (Positive/Negative or cells/mL)

This test looks for the presence of microscopic blood in the urine. Heamaturia can be caused by vigorous exercise and sexual activity, but is also an indicator of kidney disease.

Urine Leucocytes (cells/mL)

Leucocytes are a type of white blood cell. If present in the urine, this can be a sign of infection.

Urine Erythrocytes (cells/mL)

Red blood cells (erythrocytes) in the urine may be a sign of kidney disease, a blood disorder or another underlying medical condition, such as bladder cancer.

Urine Epithelial Cells (cells/mL)

A few epithelial cells may be considered normal, as they can be shed during the natural process of cell turnover and sloughing off of the urinary tract lining. However, an excess or abnormal type of epithelial cells in the urine may indicate an underlying condition or issue.

Urine Culture (Bacteria identified)

A urine culture is a test that can detect bacteria in your urine. This test can find and identify the germs that cause a urinary tract infection (UTI).

Urine Creatinine (mmol/L)

Creatinine is a waste product that your body makes when you use your muscles or when your body digests meat. Healthy kidneys remove creatinine from your blood, and it leaves your body in your urine. This test can find out whether your kidneys are working normally or to see if treatment for kidney disease is working.

Protein to Creatinine Ratio (Ratio)

Normal individuals usually excrete very small amounts of protein in the urine. Persistently increased protein excretion is usually a marker of kidney damage.
