Details about Liver and Kidney Function Test
What is the Liver and Kidney Function Test?
The Liver and Kidney Function Test is a blood test panel designed to evaluate the metabolic, detoxification and filtration functions of the liver and kidneys. These two organs play a critical role in processing nutrients, removing waste, regulating fluids and maintaining overall health.
This test measures liver enzymes, proteins, waste products and kidney filtration markers, providing a clear overview of organ performance. It is commonly used for routine health checks, investigation of symptoms, medication monitoring and early detection of disease.
Because liver and kidney issues can be silent in early stages, blood testing is often the first and most reliable way to identify problems.
What does the Liver and Kidney Function Test include?
This test includes 12 individual biomarkers, grouped below for clarity:
Liver Enzymes & Biliary Markers
- Alanine Transaminase (ALT)
- Aspartate Aminotransferase (AST)
- Alkaline Phosphatase (ALP)
- Gamma Glutamyl Transferase (GGT)
- Total Bilirubin
Proteins & Nutritional Markers
- Albumin
- Total Protein
- Globulin
Kidney Function & Filtration
- Creatinine
- Urea
- Estimated Glomerular Filtration Rate (eGFR)
Electrolytes
- Sodium
These markers together provide a balanced assessment of liver health, kidney filtration capacity and overall metabolic function.
Why do I need a Liver and Kidney Function Test?
Liver and kidney function tests are commonly requested because early organ dysfunction often causes no obvious symptoms. This test helps identify issues early, allowing intervention before complications develop.
You may benefit from this test if you have:
- Fatigue or low energy
- Abdominal discomfort or bloating
- Yellowing of the skin or eyes (jaundice)
- Dark urine or pale stools
- Swelling in the legs or ankles
- High blood pressure
- Diabetes or metabolic conditions
- Regular alcohol intake
- Use of long-term medications
- Abnormal results on previous blood tests
It is also widely used for routine health screening, medication monitoring and follow-up of known liver or kidney conditions.
Benefits of the Liver and Kidney Function Test
- Comprehensive organ assessment

Important for drugs processed by the liver or kidneys. - Assesses detoxification capacity
Liver enzymes indicate how well toxins are processed. - Evaluates kidney filtration efficiency
Creatinine and eGFR assess waste removal. - Supports chronic disease monitoring
Useful in diabetes, hypertension and metabolic conditions. - Simple blood test
Quick and minimally invasive. - Supports preventative healthcare
Helps reduce long-term organ damage risk.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
