Non-Invasive Liver Tests in Australia — What's Available and What Each One Does
Liver disease was once diagnosed with a needle. A biopsy — a small core of liver tissue extracted through the skin under local anaesthetic — was the only way to know with certainty what was happening inside the liver. The process involved hospital admission, procedural risk, significant cost, and recovery time.
That is no longer the standard approach for most patients.
Non-invasive liver tests now provide sufficient clinical information for the vast majority of patients who need liver assessment — without needles, without hospitalisation, and without recovery time. This guide covers every non-invasive option available in Australia in 2026.

Non-invasive tests have become increasingly recommended by clinical guidelines as they reduce the need for invasive procedures like liver biopsy, improving patient care and outcomes.
The practical advantages over biopsy are significant:
- No procedural risk — biopsy carries approximately 1 in 1,000 risk of serious complications
- No hospitalisation or day procedure admission required
- Results available immediately (elastography) or within days (blood tests)
- Safe for repeated monitoring — can be done annually without concern
- Cost approximately $150–$300 for elastography versus $1,500–$3,000+ for biopsy
For most patients with MASLD (fatty liver disease), the combination of a FIB-4 blood test and liver elastography provides sufficient information to guide management without biopsy.
The Australian Testing Pathway
The Medical Journal of Australia's September 2025 consensus statement establishes a clear two-step pathway for non-invasive liver assessment in Australian primary care:
Step 1 — FIB-4 score (from routine blood tests)
FIB-4 below 1.3: low risk — reassure, repeat in 3 years. FIB-4 1.3–2.67: indeterminate — proceed to Step 2 (elastography). FIB-4 above 2.67: high risk — specialist referral. After elastography: kPa below 8 is reassuring; 8–13 warrants specialist review; above 13 is urgent referral.
Patients with an indeterminate FIB-4 score (1.3–2.7) should undergo second-line assessment with liver elastography or a direct liver fibrosis serum test, or if these tests are unavailable, should be referred to a clinician with expertise in liver disease.

Test 1 — FIB-4 Score (Blood Test)
What it is: A mathematical calculation using four values already in your blood panel — age, ALT, AST, and platelets.
What it is: A mathematical calculation using four values already in your blood panel — age, ALT, AST, and platelets.
What it measures: Risk probability of significant liver fibrosis. Not a direct measurement — a risk stratification tool.
How to get it: Ask your GP to calculate it from your routine blood panel. No additional tests needed if you have had a recent blood panel.
- Below 1.3: Low risk — repeat in 3 years
- 1.3–2.67: Indeterminate — proceed to elastography
- Above 2.67: High risk — specialist referral
Cost: No additional cost — uses existing blood results.
Limitation: While FIB-4 is highly effective in ruling out advanced fibrosis, its ability to detect early-stage fibrosis is limited. Many patients with intermediate FIB-4 scores require further testing using more advanced imaging modalities such as vibration-controlled transient elastography.
Test 2 — Transient Elastography (FibroScan / Guided Elastography)
What it is: A non-invasive scan that measures liver stiffness (kPa) and liver fat content (CAP score) using a mechanical pulse through the skin of the abdomen.
What it measures: Liver stiffness as a proxy for fibrosis stage (F0–F4). Liver fat content as steatosis grade (S0–S3).
How to get it: Clinic booking with or without GP referral depending on the clinic. Takes 10–15 minutes.
Results: kPa below 8 = reassuring. 8–13 = moderate to significant fibrosis. Above 13 = cirrhosis range.
Cost: Approximately $150–$300 at private Australian clinics. No Medicare rebate for most MASLD indications. Some private health insurers provide partial cover.
Best for: Second-line assessment after indeterminate FIB-4. Monitoring MASLD progression. Assessing treatment response including GLP-1 therapy for MASH.
Devices: FibroScan (Echosens) is the most widely used brand. Guided elastography systems add real-time ultrasound imaging to reduce operator variability — particularly useful in patients with higher BMI.
Limitation: Accuracy reduces with high BMI on standard probes. Active liver inflammation can temporarily inflate stiffness readings. Requires fasting.

What it is: Liver stiffness measurement using high-end ultrasound machines from manufacturers including SuperSonic Imagine (Aixplorer) and Samsung. This technique measures the speed of ultrasound waves as they pass through the liver. The shear wave is a perpendicular wave produced as a result of a generated ultrasound pulse through the tissues. By measuring the speed of the wave we can determine the stiffness of the tissue.
What it measures: Liver stiffness (kPa) with a colour-coded stiffness map of the liver — a visual representation alongside the quantitative score.
How to get it: Available at imaging centres with 2D-SWE capable ultrasound equipment. GP referral typically required.
Results: Different kPa reference ranges to FibroScan — always interpret results against the specific device's reference range, not FibroScan thresholds.
Cost: Approximately $200–$400 at specialist imaging centres. May attract Medicare rebate under specific indications.
Best for: Patients at specialist imaging centres already having abdominal ultrasound. Useful when a broader anatomical assessment of the liver is needed alongside stiffness measurement.
Limitation: Not universally available. Different reference ranges require careful interpretation. Less extensively validated across all liver disease subtypes compared to VCTE.
Test 4 — Enhanced Liver Fibrosis Panel (ELF Test)
What it is: A blood test measuring three direct markers of fibrosis activity — hyaluronic acid, PIIINP (a collagen precursor), and TIMP-1 (a tissue inhibitor of metalloproteinase).
What it measures: Unlike FIB-4 which uses indirect markers, the ELF test provides safer, more accessible methods for identifying liver fibrosis and guiding clinical management. It directly measures proteins involved in the fibrosis process.
How to get it: Blood draw at GP or specialist. Processed by reference laboratory — results within days.
- ELF score below 7.7 = low risk
- 7.7–9.8 = moderate risk
- Above 9.8 = high risk of advanced fibrosis
Cost: Approximately $50–$150 depending on laboratory.
Best for: Complement to elastography in specialist settings. Monitoring fibrosis activity in patients already under specialist care. The Liver Foundation Australia notes ELF test as a validated second-line test alongside elastography for patients with indeterminate FIB-4.
Limitation: Not yet part of routine GP referral pathways in Australia. Requires reference laboratory — not immediately available.

What it is: Liver stiffness measurement across the entire liver volume using magnetic resonance imaging technology. Imaging tests, including ultrasound-based elastography and magnetic resonance elastography, are superior to blood-based non-invasive liver disease assessments and recommended, if available, to identify patients with significant to advanced fibrosis or cirrhosis.
What it measures: Liver stiffness (kPa) across the full liver — more comprehensive than probe-based approaches. Also measures liver fat content using proton density fat fraction (PDFF) — more precise than CAP scoring.
How to get it: Specialist referral required. MRI-compatible patients only (no ferromagnetic implants). Takes 30–45 minutes including standard liver MRI sequences.
Cost: Approximately $500–$900+ at specialist centres with MRI elastography capability.
Best for: Complex cases where FibroScan or 2D-SWE are inconclusive. Patients with very high BMI where ultrasound-based probes are unreliable. Research and clinical trial settings. Pre-surgical liver assessment.
Limitation: Most expensive non-invasive option. Limited availability — not all MRI centres offer elastography sequences. Overkill for routine MASLD screening. Requires MRI appointment and specialist ordering.
Test 6 — Liver Biopsy (Invasive — Included for Comparison)
What it is: A needle is inserted through the skin under local anaesthetic to extract a small core of liver tissue for laboratory analysis. The diagnostic gold standard.
What it measures: Definitive fibrosis staging (F0–F4). MASH diagnosis (inflammation). Full histological assessment of liver disease.
Cost: $1,500–$3,000+ including procedure, pathology, anaesthesia, and facility fees.
Best for: Cases where non-invasive tests are inconclusive and management decisions require certainty. Definitive MASH diagnosis for treatment eligibility. Clinical trial enrolment requiring biopsy-confirmed diagnosis.
Limitation: Invasive with approximately 1 in 1,000 risk of serious complications. Hospital or day procedure admission required. Sampling error — each biopsy samples approximately 1/50,000th of the total liver volume. Expensive. Not appropriate for routine or serial monitoring.
For most patients with MASLD, the FIB-4 → elastography pathway provides sufficient information without biopsy.

Frequently asked questions
What is the most accurate non-invasive liver test in Australia?
Imaging tests including ultrasound-based elastography and MRI elastography are superior to blood-based non-invasive assessments for identifying significant to advanced fibrosis or cirrhosis. For routine clinical use at accessible cost, the combination of FIB-4 and transient elastography provides the best balance of accuracy and practicality for most Australian patients.
Can a blood test diagnose liver fibrosis?
The FIB-4 score stratifies risk of fibrosis but does not provide a direct fibrosis stage. It is a screening tool with high accuracy for ruling out advanced fibrosis (below 1.3) but requires elastography for definitive assessment in the indeterminate range (1.3–2.67). The ELF test provides more direct measurement but is less widely available in Australian primary care.
Is FibroScan bulk billed in Australia?
A small number of Australian clinics offer bulk billing for liver elastography under specific clinical indications. Most charge privately at $150–$300. There is no universal Medicare item number for transient elastography in MASLD indications as of 2026, though this is being actively advocated for following the September 2025 MJA consensus statement.
Do I need a specialist referral for a non-invasive liver test?
For the FIB-4 score — no. Your GP calculates it from existing blood results. For liver elastography — several Australian clinics accept self-referred patients without a GP letter. Check with your specific clinic when booking. The ELF test and MRI elastography typically require specialist ordering.
How often should I have non-invasive liver testing?
If FIB-4 is low risk (below 1.3): repeat in 3 years. If on GLP-1 treatment for MASH: elastography annually to assess treatment response. Your GP or hepatologist will advise the appropriate interval for your specific situation.
Why can't my GP just use ultrasound to check my liver?
A standard abdominal ultrasound can detect significant hepatic steatosis (the liver appears bright on ultrasound) but cannot measure fibrosis — the most important prognostic factor in MASLD. Conventional B-mode ultrasound provides anatomical information and when combined with shear wave technology it can now evaluate fibrosis in patients with liver disease. Elastography is required for fibrosis staging. The two tests serve different purposes.
