Keeping a clear record of your liver blood test results is one of the most practical steps you can take to stay informed about your liver health over time. Whether you've had a single liver function test or several across different months, knowing how to organise, interpret, and track your results helps you have more meaningful conversations with healthcare professionals and gives you a clearer picture of how your liver is performing.
This guide is designed to help anyone in London — and across the UK — understand what their liver results include, how to track changes over time, and why consistent monitoring can be a valuable part of a proactive approach to wellbeing.
What Is a Liver Function Test and What Does It Measure?
A liver function test (LFT) is a blood test that measures several enzymes, proteins, and substances produced or processed by the liver. It is one of the most commonly requested blood panels in both NHS and private healthcare settings.
In a standard liver function test, results typically include the following biomarkers:
| Biomarker | What It May Indicate |
|---|---|
| ALT (Alanine Aminotransferase) | Enzyme activity in liver cells; elevated levels can suggest liver stress |
| AST (Aspartate Aminotransferase) | Found in the liver and other tissues; may highlight cellular changes |
| ALP (Alkaline Phosphatase) | Associated with bile duct and bone activity |
| GGT (Gamma-Glutamyl Transferase) | Can be sensitive to alcohol intake and certain medications |
| Bilirubin | A breakdown product of red blood cells processed by the liver |
| Albumin | A protein made by the liver; may reflect overall liver function |
| Total Protein | Reflects the balance of proteins the liver produces |
Practical Insight: No single biomarker tells the full story. A pattern of results across several tests over time is far more informative than a single reading in isolation.
Why Tracking Your Results Over Time Matters
A one-off liver blood test provides a snapshot — it reflects your liver's status at a particular point in time. However, a series of results tracked across weeks or months can reveal trends that a single test cannot.
For example:
When you keep a well-organised record of your liver blood results, you're better equipped to notice these patterns — and to share them clearly if you consult a nurse, doctor, or other healthcare professional.
Practical Insight: Think of your liver results record as a personal health timeline. Each result is a data point; the value lies in seeing them together.

How to Build a Clear Record of Your Liver Blood Results
Step 1 — Collect All Previous Results in One Place
Start by gathering every liver function test report you've received. These may be from:
If you've had results emailed or posted to you, save digital copies in a clearly labelled folder. For paper results, consider scanning them so you have a digital backup.
Step 2 — Create a Simple Tracking Spreadsheet or Table
A basic spreadsheet with the following columns can help you track your results clearly over time:
| Date of Test | ALT | AST | ALP | GGT | Bilirubin | Albumin | Notes |
|---|---|---|---|---|---|---|---|
| 10/01/2026 | 28 | 22 | 74 | 30 | 12 | 41 | Routine screening |
| 05/04/2026 | 35 | 25 | 80 | 44 | 14 | 40 | After dietary changes |
| 09/10/2026 | 30 | 21 | 76 | 31 | 11 | 42 | Follow-up test |
Add a Notes column to record any relevant context — such as recent illness, dietary changes, alcohol intake adjustments, or new medications. Context matters when reviewing trends.
Step 3 — Note the Reference Ranges From Each Report
Reference ranges can vary slightly between laboratories. Always note the reference range provided on your specific report alongside your result. This ensures you're comparing like-for-like when speaking with a healthcare professional.
Step 4 — Date and Label Everything Consistently
Use the UK date format (DD/MM/YYYY) throughout your record. Ensure each entry includes the name of the clinic or provider, the test type, and the date the sample was taken — not the date the report was issued, as these can differ.
Who Should Consider Regular Liver Blood Testing?
Regular liver function monitoring may be worth considering for some adults, including those who:
Please note: This list is not exhaustive and is intended as general educational information only. Whether liver function monitoring is appropriate for you depends on your individual health circumstances. Please consult an appropriately qualified healthcare professional for personalised guidance.
You can explore our liver function blood test options to understand what's included in a private panel.
Practical Insight: There is no universally "right" frequency for liver testing. Some individuals benefit from quarterly checks; others may opt for annual screening. Discussing your personal health context with a healthcare professional can help guide an appropriate schedule.
How Often Should You Test?
There is no one-size-fits-all answer to how frequently you should have a liver blood test. The following guidance provides a general framework, though individual needs will vary:
If you're considering private health screening in London, our nurse-led team can discuss the most suitable testing schedule based on your personal health goals.
Understanding What Your Results Mean
Liver blood results are reported alongside reference ranges, which represent the values typically found in a healthy adult population. A result outside the reference range does not automatically indicate a serious problem — it may simply prompt further investigation or a repeat test.
Here's a general orientation:
If you'd like to understand the full scope of markers available, our full blood count and biochemistry panels include options relevant to liver health assessment.
Practical Insight: Always share your results record — including dates and context notes — when consulting any healthcare professional. The fuller the picture, the more useful the conversation.
NHS vs Private Liver Blood Testing in London: A Practical Comparison
| Aspect | NHS Testing | Private Testing (London) |
|---|---|---|
| Access | Requires GP referral in most cases | Self-referral, no GP needed |
| Waiting time | Can vary; may involve delays | Often same-day or next-day appointments |
| Results turnaround | Typically 5–10 working days via GP | Often within 24–48 hours |
| Flexibility of timing | Appointment-dependent | Flexible booking, including weekday and weekend slots |
| Cost | Free at point of use | Fee applies; see clinic website for current pricing |
| Report format | Shared via GP | Sent directly to you |
Both routes are entirely valid and often complementary. Many Londoners choose private liver testing to access results more quickly, particularly between NHS appointments, or when they want to take a proactive approach outside of the standard referral pathway.

Frequently Asked Questions
What does a liver blood test result record include?
A liver blood test results record typically includes the date of each test, the values for key biomarkers such as ALT, AST, ALP, GGT, bilirubin, and albumin, along with the laboratory reference ranges. Including contextual notes — such as recent dietary changes or medication use — adds further value to the record over time.
How often should I have a liver function blood test?
Most adults choosing proactive liver health monitoring opt for annual testing, though some may benefit from testing every three to six months. The right frequency depends on your personal health context, lifestyle, and any existing conditions. It's worth discussing with a healthcare professional to determine what's appropriate for you.
Can I track my liver blood results at home?
Yes. A simple spreadsheet or printed table is sufficient for most people. Record the date, each biomarker value, the reference range provided, and any notes about your health at that time. Keeping results in chronological order makes it easier to spot trends over time.
What is the most important marker in a liver function test?
There is no single most important marker. ALT is often considered the most liver-specific enzyme, but a full liver function test looks at multiple biomarkers together. Patterns across all markers — and across multiple tests — are more meaningful than any single result in isolation.
Should I fast before a liver blood test?
Fasting is not always required for a liver function test, though some clinics recommend fasting for 8–10 hours before testing to ensure consistent conditions across results. It's best to follow the guidance provided by your testing clinic at the time of booking.
What can cause a temporary rise in liver enzymes?
A range of factors can temporarily affect liver enzyme levels, including recent intense physical exercise, alcohol consumption, certain over-the-counter medications, viral illnesses, and some dietary supplements. This is why context notes in your results record are so useful when reviewing trends over time.
Is a private liver blood test in London reliable?
Reputable, accredited private blood testing clinics are subject to UK regulatory quality standards for laboratory testing. For assurance, patients should confirm that any clinic they use holds appropriate accreditation, such as UKAS accreditation for its laboratory provider. Results are reported with reference ranges to support clear interpretation.
What should I do if my liver blood test results are outside the reference range?
A result outside the reference range does not automatically indicate a serious concern. It may reflect a temporary factor or prompt a repeat test. Share your results — including your tracking record — with an appropriate healthcare professional, who can advise on whether further investigation is needed.
Can I book a liver function test without a GP referral in London?
Yes. At our nurse-led private blood testing clinic in London, you can self-refer for a liver function test without needing a GP referral. Results are sent directly to you, giving you timely access to your health information.
How do I compare my results across different laboratories?
Reference ranges can vary slightly between laboratories due to differences in equipment and methodology. When tracking results across multiple providers, always note the reference range used by each lab, and avoid comparing raw numbers without accounting for these differences.
A Final Thought: Proactive Awareness Supports Better Health Conversations
Taking ownership of your liver blood results — by organising, dating, and tracking them over time — is a straightforward but genuinely impactful step. It puts you in a stronger position when speaking with any healthcare professional, and it helps you engage with your own health data in a meaningful way.
If you're ready to take the next step, consider booking a liver function blood test at our London clinic. Our nurse-led team provides professional, confidential testing with results you can access promptly and retain as part of your personal health record.
