How to Check Liver Function at Home? Testing for Liver Health

If you're feeling constantly tired, experiencing abdominal discomfort, or noticing unusual skin changes or weight loss, your liver health might be at risk. Liver issues often go unnoticed until symptoms worsen, making early detection essential. 

A liver function blood test can help identify potential health problems by measuring key enzymes and proteins. With home blood testing kits, you can check your liver health easily and privately without needing to visit a clinic. 

This guide will provide you with all the details for the common symptoms of liver disorder, what’s included in liver blood tests, and how to check liver function at home! So, let’s dive into it!

How to Check Liver Function at Home (Without Testing)?

While medical testing is the most accurate way to assess liver health, you can still observe several physical signs that may indicate your liver isn’t functioning properly. Paying attention to these early warning signs at home can help you recognize when to seek medical advice or testing.

Here are some key indicators your liver health may be at risk:

  • Persistent fatigue or low energy levels: If you're feeling unusually tired for extended periods, it could be a sign your liver is under stress.
  • Abdominal Pain: Another usual symptom of liver disorder is constant abdominal pain and discomfort despite taking small and easily digestible food.
  • Jaundice: You can observe yellowing of the skin and eyes if bilirubin builds up in your body, often due to impaired liver function.
  • Dark urine: Dark-colored urine is usually a sign of dehydration, but if this problem persists for a long, it may indicate liver or bile duct issues.
  • Digestive discomfort: Liver disorders may affect digestion, leading to bloating, nausea, or vomiting.
  • Sudden weight loss: A noticeable and sudden weight loss can be linked to chronic liver conditions.
  • Skin Infections: Increased skin sensitivity and rashes may be a sign of bile buildup due to liver dysfunction.
  • Bloating: Fluid retention (ascites) can be a common symptom of advanced liver disease.

In addition to these signs, your lifestyle choices can also give clues about your liver’s condition. Excessive alcohol, high-fat foods, a sedentary lifestyle, and certain medications can increase the burden on your liver.

If you’re experiencing any combination of these symptoms, it’s wise to consult a healthcare provider or consider a liver function test to check your liver health. Early detection is essential to prevent serious complications.

When Should You Consider a Liver Function Test?

A liver function test is essential for detecting early signs of liver damage or disease, even before major symptoms appear. You should consider taking a liver test if you're experiencing ongoing health issues that may indicate poor liver health. Recognizing these warning signs early can help you take timely action and avoid complications.

What is Included in a Liver Blood Test?

A liver blood test, also known as a Liver Function Test (LFT), checks how well your liver is working. A comprehensive liver profile measures the levels of key biomarkers to help detect liver damage or dysfunction:

  • ALT (Alanine Aminotransferase) or SGPT: An Enzyme found in the liver that helps convert protein into energy. Elevated levels may suggest liver inflammation or damage.
  • AST (Aspartate Aminotransferase) OR SGOT: Enzyme that breaks down amino acids (building blocks of proteins). High levels may indicate liver or muscle damage.
  • ALP (Alkaline Phosphatase): Enzyme present in the bones and liver and helps break down complex proteins into smaller units. Elevated ALP may be an indication of liver or bone-related disorders.
  • GGT (Gamma-Glutamyl Transferase): A liver enzyme that, when elevated, may signal liver dysfunction or bile duct issues.
  • TBIL (Total Bilirubin): A waste product formed from the breakdown of red blood cells. High bilirubin can indicate anemia, liver disease, or a blocked bile duct.
  • ALB (Albumin): A protein produced by the liver that supports immune function. Low levels may suggest liver or kidney problems or gastrointestinal conditions.

How to Check Liver Function at Home with Blood Testing? Step-by-Step Guide

Checking your liver health at home is a simple, safe, and reliable process. Start by choosing a trusted clinic that offers Liver Profile home sampling. Once you place your order, you’ll receive a complete liver function test (LFT) kit, including detailed instructions and secure packaging for both delivery and return. 

Follow the step-by-step guide mentioned below to collect your blood sample using the finger-prick method, ensuring your hands and tools are clean and sterile. Then, return your sample to the lab for analysis. Results are usually available within a few working days. 

Ensure Hygienic Conditions

Wash your hands thoroughly with lukewarm water. Clean the finger (ring or middle finger) and the surrounding area with alcohol swabs to ensure a germs-free setup.

Get Testing Kit Ready

Open your finger-prick blood test kit containing a lancet, sterilization swabs, instructions manual, and blood collection tubes. Place them on a flat and clean surface.

Collect Your Sample

Using the lancet, prick your finger following the instructions provided with the kit. Make sure to be calm while collecting your sample to prevent errors. When the blood drop appears, gently massage your finger downward to let the blood drip naturally into the collection tube. 

Seal the Kit Securely

Once the required sample is collected, pack the kit carefully and label it as instructed. Make sure that the sample tubes are properly sealed and packed.

Return the Sample

Return your sample to the lab using the envelope provided. Your results will typically be ready in 2-3 working days.

Why are Liver Function Tests Performed?

Liver Function Tests (LFTs) are essential to help you assess the performance of your liver and detect underlying issues. These tests are usually performed to:

  • Evaluate the risk or early signs of liver disease.
  • Investigate visible signs of liver dysfunction.
  • Monitor the impact of certain medications on liver health.
  • Screen for infections such as hepatitis and other liver-related conditions.

Are Home Liver Tests Accurate?

Yes, home liver tests can be highly reliable when processed by accredited UK laboratories that follow the same strict standards as NHS labs. When choosing a provider, ensure they use certified labs, have trained clinical staff, and maintain high-quality equipment and procedures.

The accuracy of your results also depends on how well you follow the self-sampling instructions provided with the finger-prick test kit. With proper technique and lab standards in place, home liver function tests offer a convenient and trustworthy way to monitor your liver health.

Home Vs Clinic Blood Sampling: Which One Should I Choose to Check Liver Function?

Choosing between home and clinic blood sampling for a liver function test depends on your lifestyle, comfort, and health needs. Home blood testing is generally ideal for those with busy routines or who have travel issues due to age or some health problems.

On the other hand, clinic-based testing may be more suitable if you’re not confident in collecting your sample or have specific medical conditions that require professional supervision. Clinics also offer immediate support if any issues arise during the blood draw.

Here are the pros and cons of each blood sampling method explained below:

Home or Self-sampling

Pros

  • Convenience
  • No need to visit the clinic
  • Ideal for people having tough schedules
  • Private and secured lab results

Cons

  • Following proper instructions is mandatory
  • Slight risk of errors if instructions are not followed properly

Clinic Blood Sampling

Pros

  • Testing by trained healthcare professionals
  • Ideal for those not comfortable with self-sampling
  • Suitable for venous blood draws

Cons

  • Requires time management for appointments and lab visits
  • May need to wait for long hours 

Conclusion

Observing visible signs like fatigue, jaundice, or digestive discomfort can give you early clues about your liver health. While home liver function test kits offer a convenient way to monitor key biomarkers, it’s always best to consult a healthcare professional if symptoms persist or worsen to ensure accurate diagnosis and timely treatment.
