Details

Your liver is a vital powerhouse that performs over 500 essential functions every single day, including filtering out toxins, regulating chemicals like hormones, and storing nutrients for energy. However, modern lifestyle factors—such as regularly drinking alcohol or carrying extra weight—can place significant stress and strain on this hard-working organ.

Because liver damage and inflammation typically cause no obvious symptoms in their early stages, proactive screening is your best line of defence. The good news is that in its early stages, liver damage is usually completely reversible. The Optimal You Liver Function Blood Test checks 7 key biomarkers to evaluate how well your liver is functioning and spot early signs of cellular damage or inflammation. Whether you want to assess the impact of your lifestyle or track your progress after making positive health changes, this test gives you the clinical clarity you need.

What We Test: The 7 Liver Biomarkers

Our targeted panel analyses specific liver enzymes and blood proteins to give you a transparent look at your hepatic health:

Biomarker Group Biomarker What It Measures
Liver Health & Enzymes ALT (Alanine Transferase)

An enzyme found mostly inside liver cells that is released into the blood when the liver is actively damaged.

GGT (Gamma-Glutamyl Transferase)

An enzyme in the bile ducts that is highly sensitive to alcohol consumption and general liver stress.

ALP (Alkaline Phosphatase)

An enzyme found in the liver and bones; elevated levels frequently indicate blocked or obstructed bile ducts.

Bilirubin

A yellow substance produced during the natural breakdown of old red blood cells; high levels can cause jaundice.

Proteins Total Protein

The combined sum of the two primary protein types (albumin and globulin) circulating in your bloodstream.

Albumin

The main protein produced by the liver, essential for keeping fluid from leaking out into other body tissues.

Globulin

A group of proteins created by the liver and immune system to help your body fight off infections and transport nutrients.

⚠️ Test Limitations: This test checks liver enzyme levels but does not diagnose specific medical conditions. It may not always detect the early stages of fatty liver disease (metabolic dysfunction-associated steatotic liver disease).

📋 Essential Pre-Test Instructions

To ensure your laboratory results are perfectly accurate and unaffected by outside variables, please follow these preparation protocols carefully:

Activity & Lifestyle (48 Hours Before)

Avoid Alcohol: Do not drink alcohol for at least 48 hours before collecting your sample, as it can significantly alter your liver enzyme levels.

Rest Up: Avoid vigorous exercise for 48 hours prior to your test, as intense physical exertion can temporarily spike liver enzyme levels.

Short-Term Illness: Only take this test once any acute or short-term illness symptoms have completely settled.

Hydration & Fasting

- Stay Hydrated: Ensure you drink plenty of water and stay well-hydrated before collecting your blood sample.

-No Fasting Required: You do not typically need to fast for this liver profile unless your doctor has specifically advised otherwise.

Medications & Supplements

Routine Medications: You are allowed to take any regularly prescribed or over-the-counter medications exactly as you would normally.

Biotin Supplements: Do not take biotin supplements for two days before this test. If it is a prescribed supplement, please discuss this with your doctor first.

How It Works

1. Order Your Kit: Purchase your test online to receive a discreet collection kit delivered straight to your door for free.

2. Flexible Testing Options: Conveniently collect your sample at home via a quick finger-prick method, or choose from our professional clinic collection options.

3. Fast Turnaround: Return your sample using the provided pre-paid envelope. Your comprehensive results will be securely uploaded to your portal in an estimated 2 working days.

4. Bespoke Doctor's Report: Every test includes a personalised medical review and actionable advice written by a qualified doctor to help explain your markers.

Frequently Asked Questions

Frequently asked question about our blood testing and diagnostic services. If there is a question not answered feel free to contact us!

Are there any age restrictions for your tests?

Yes, our services are currently available only to individuals aged 18 and over. We require you to confirm your Date of Birth in your Customer Account area.

Can I book a professional to take my blood?

Yes! We offer options for a clinic visit or a nurse home visit for a professional venous draw. You can select this option when choosing which test is right for you!

If you prefer to book your own phlebotomist, no problem! Simply select this option prrior to processing your order and we will send the kit to your home for you to arrange your own clinic visit.

Can I share my results with my own GP?

Yes, and we encourage it! You can download your doctor-reviewed report as a PDF from your secure portal to share with your GP or specialist during your next appointment.

Can I take these tests if I am pregnant or breastfeeding?

While you can take the tests, pregnancy and breastfeeding significantly alter your hormone and nutrient levels. This means our standard "normal" ranges may not apply to you. We recommend consulting your midwife or GP before ordering.

Can I use these tests to monitor an existing medical condition?

Our tests are excellent for tracking trends and monitoring wellness. However, they should not be used to self-diagnose or adjust prescribed medication without first consulting your treating physician and GP.

Do I need a doctor’s referral or a prescription?

No. Optimal You provides a private service that allows you to take control of your health data without needing to visit a GP first.

How do I get started with a blood test?

Simply choose your test on our website and checkout. 

Whilst on the particular test you are looking to purchase, select a test type from the drop down. You have three or four options depending on the type of test you are purchasing:

At Home Finger Prick Blood Test - You will receive you sample kit via the post. Simply follow the instructions enclosed and return using the packaging provided.

Book a Venous Draw at a Clinic - You will receive an email after you have processed your order containing instructions on how to book your clinic appointment. Our partners have national coverage of the UK to make your sample collection convenient to you whilst maintaining our quick service times. You can find your closest clinic via our partner medichecks on our clinic finder page.

Book a Venous Draw at Home with a Nurse - Once you have chosen this option, simply go through our checkout process, a nurse will be in touch to book your at home visit to complete your sample.

Self arrange a Profesional Sample Collection - You will receive your sample collection kit in the post for you to take to your chosen phlebotomy clinic. Note you will be responsible for arranging your appointment and for any associated fees.

How long does it take to get my results?

Most results are ready within 2–5 working days after the lab receives your sample. You will receive an email notification as soon as they are ready.

How soon do I need to post my sample back?

To ensure the stability of your biomarkers, you should post your sample on thesame dayyou collect it. Avoid collecting samples on a Friday afternoon or over the weekend to prevent them from sitting in the post; Monday through Thursday is best.

Is my data secure?

Absolutely. We use industry-standard encryption, and your data is stored securely in compliance with GDPR. Only you and our medical team have access to your results.

Is there a specific day or time I should take my sample?

Most tests are best performed first thing in a morning, especially if fasting is required. For hormonal tests (like Testosterone or Menopause profiles), we usually recommend collecting your sample before 10:00 AM when hormone levels are most stable.

You will receive additional guidance post purchase to give you all of the information needed as some tests have different guidelines.

What happens if I struggle to get enough blood from a finger-prick?

Don't worry, it happens! We include extra lancets in every kit. Pro tip: Make sure your hands are very warm (try soaking them in warm water) and stay well-hydrated for 24 hours before your test. If you still can't collect enough, contact us and we can help you arrange a venous blood draw instead.

What happens if my results are abnormal?

If a result is critically outside the normal range, our medical team will highlight this and provide clear guidance on the next steps during our contact with you, which may include you seeing your GP, going to A&E or calling the NHS on '111'.

What is the difference between a Finger-Prick and a Venous Draw?

A finger-prick is a self-collection kit done at home. A venous draw is a traditional blood sample taken from a vein by a professional. Some advanced tests (like our TRT or Enhanced Profiles) require a larger sample and are best done via a venous draw.

Who reviews my results?

Every report is reviewed by a qualified UK doctor. They provide personalized comments to help you understand what your biomarkers mean for your health.

Why are my results different from a previous test I had?

Biomarkers can fluctuate based on the time of day, your diet, stress levels, recent exercise, or even the lab equipment used. This is why we focus on "ranges." If you see a significant change, our medical team’s comments will help put that data into context.
