Overview of the Advanced Kidney Profile
The Advanced Kidney Profile is a 13-marker blood test designed to provide a detailed assessment of kidney filtration, electrolyte balance, acid-base regulation and minerals influenced by renal physiology.
The test contains 13 biomarkers: Sodium, Potassium, Urea, Creatinine, Cystatin-C, Calcium, Corrected Calcium, Albumin, Magnesium, Phosphate, Uric Acid, Chloride and Bicarbonate.
The kidneys continuously filter waste products from the blood while regulating fluid balance, electrolytes and acid-base status.
Creatinine is one of the most commonly used markers of kidney filtration, but its concentration can be influenced by muscle mass, diet and Creatine supplementation.
Cystatin-C provides a complementary filtration marker that is generally less dependent on muscle mass.
Urea provides further information about renal clearance but can also vary with hydration, protein intake and catabolic states.
Sodium, Potassium, Chloride and Bicarbonate provide information about electrolyte and acid-base balance.
Calcium, Corrected Calcium, Magnesium and Phosphate are influenced by interactions between the kidneys, bone and endocrine system.
Albumin provides context for Total Calcium, while Uric Acid is cleared significantly through the kidneys and can become elevated when renal excretion is reduced.
Early chronic kidney disease can be clinically silent, which means laboratory monitoring can identify abnormalities before obvious symptoms develop.
What Does the Advanced Kidney Profile Check?
The profile examines several different aspects of renal physiology, combining filtration markers with electrolytes, acid-base markers and minerals regulated partly through kidney function. This test contains 13 biomarkers.
Urea - Measures a nitrogen-containing waste product influenced by renal clearance, hydration and protein metabolism.
Creatinine - Measures a muscle-derived waste product routinely used when assessing kidney filtration.
Cystatin-C - Provides an additional kidney-filtration marker that is less dependent on muscle mass than Creatinine.
Sodium - Measures the principal extracellular electrolyte involved in fluid balance, nerve transmission and cellular function.
Potassium - Measures an electrolyte essential for muscle activity and normal cardiac electrical function.
Chloride - Measures an electrolyte involved in fluid balance and acid-base regulation.
Bicarbonate - Provides information about metabolic acid-base balance and the body's buffering system.
Calcium - Measures total circulating Calcium.
Corrected Calcium - Adjusts the Calcium result according to Albumin to provide additional context.
Magnesium - Measures an essential mineral involved in neuromuscular function, energy metabolism and electrolyte regulation.
Phosphate - Measures a mineral whose balance is strongly influenced by the kidneys, Vitamin D and Parathyroid Hormone.
Albumin - Measures a major circulating protein and provides context for interpreting Calcium.
Uric Acid - Measures a waste product of purine metabolism that is influenced significantly by kidney excretion and is associated with gout when elevated.
Who May Benefit From the Advanced Kidney Profile?
This profile may be useful when detailed renal monitoring is required or when diabetes, hypertension, medication or previous blood results increase concern about kidney function.
People with diabetes - Diabetes is one of the leading causes of chronic kidney disease.
People with high blood pressure - Hypertension can both contribute to and result from impaired kidney function.
People with a previous raised Creatinine result - Cystatin-C can provide additional information about filtration.
People with a previously reduced kidney-filtration estimate - Repeat testing can establish whether a change persists.
People with unusually high muscle mass - Creatinine can be higher because of muscle mass, making Cystatin-C useful as a complementary marker.
People with very low muscle mass - Creatinine can underestimate impairment when muscle production is reduced.
People taking medicines that require kidney monitoring - Renal clearance affects the safety and dosing of many medicines.
People with recurrent gout - Uric Acid and kidney function are closely related.
People with previous electrolyte abnormalities - Sodium, Potassium, Chloride, Bicarbonate and Magnesium are included.
People with known kidney disease - Serial monitoring can show whether filtration and electrolyte balance remain stable.
Symptoms and Reasons to Consider the Advanced Kidney Profile Test
Early kidney disease frequently produces no symptoms, so testing is often prompted by risk factors or previous abnormal laboratory results.
Swelling of the ankles or legs - Fluid retention can occur with kidney disease but also has cardiac, venous and other causes.
A significant change in urine output - Reduced or increased urine production can occur with renal or fluid-balance disorders.
Persistent high blood pressure - Kidney and blood-pressure regulation are closely linked.
Foamy urine - Persistent foaming can be associated with urinary protein and may warrant additional urine testing.
Repeated gout attacks - Raised Uric Acid can contribute to urate-crystal formation.
Muscle cramps or weakness with possible electrolyte disturbance - Potassium, Magnesium, Sodium or Calcium abnormalities may contribute.
A previous raised Creatinine result - More detailed filtration testing can provide additional context.
A previous abnormal Potassium or Sodium result - Repeat testing can determine whether the disturbance persists.
No symptoms but diabetes or hypertension - Kidney impairment can develop silently in higher-risk patients.
Markedly reduced urine output, severe swelling, confusion, significant breathlessness or rapidly worsening kidney results requires prompt medical assessment.
A routine kidney profile should not delay urgent investigation of suspected acute kidney injury.
How to Prepare
Kidney markers are influenced by hydration, muscle activity, supplements and medication, so maintaining normal conditions before testing helps provide a representative result.
Do not deliberately drink excessive amounts of water in an attempt to improve kidney results.
The purpose of the test is to measure your usual kidney and electrolyte status rather than a temporarily altered state.
How to Book Your Advanced Kidney Profile
The Advanced Kidney Profile can be booked privately for detailed renal and electrolyte assessment.

Select your sample collection option
Choose an in-clinic blood draw or professional home or hotel phlebotomy depending on availability.
Attend your appointment
A trained healthcare professional collects the required venous blood sample.
Laboratory analysis
Kidney filtration, electrolyte, acid-base, mineral and metabolic markers are measured.

Your authorised kidney report is delivered securely for review.
When Will I Receive My Results?
The expected turnaround for the Advanced Kidney Profile is approximately 1–2 business days after laboratory receipt.
Most of the included markers are routinely processed biochemistry measurements, while Cystatin-C provides an additional renal filtration assessment.
The complete profile is released after all included markers have undergone laboratory analysis, quality-control procedures and authorisation.
Turnaround starts when the laboratory receives the sample rather than necessarily from the time your blood is collected.
Courier schedules, weekends, bank holidays, specimen issues or occasional repeat analysis can extend reporting.
Understanding Your Results
The Advanced Kidney Profile should be interpreted by considering filtration markers, electrolytes and mineral balance together.
A higher Creatinine or Cystatin-C result can indicate reduced kidney filtration, although each marker can be influenced by additional factors.
Urea can rise with reduced kidney clearance but also with dehydration or high protein turnover.
Potassium is clinically important because significant elevations or reductions can affect cardiac electrical activity.
Sodium abnormalities commonly reflect disturbances in water balance rather than simply too much or too little dietary salt.
Bicarbonate provides information about metabolic acid-base regulation and may decrease when the kidneys cannot adequately maintain acid-base balance.
Raised Uric Acid increases the likelihood of gout but does not mean that every person with an elevated result will develop gout.
Abnormal Calcium, Magnesium or Phosphate may require assessment of kidney function, Vitamin D, Parathyroid Hormone or medication depending on the pattern.
