What is a liver function test?

Your liver is an organ with many important functions. Some of its functions are that it removes wastes and toxins from your blood, produces bile which aids in food digestion, produces cholesterol and other fat-carrying proteins for the rest of the body, processes hemoglobin, regulates blood clotting, and converts excess glucose to glycogen for storage.

This at home liver function test measures the levels of liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (GammaGT), alkaline phosphatase (ALP), and bilirubin in the blood. The results of this test can indicate how well your liver is functioning, as well as signs of damage or disease. The test is a finger prick test that you can easily take from home. Your sample will then be examined by a certified laboratory and you will receive the results within a matter of days. It couldn’t be easier!

When should I take this liver function test?

The liver function test of Homed-IQ will look at markers to ensure that your liver is performing properly. Elevated enzyme levels may indicate acute or chronic liver disease.

Reasons to take this test include:

  • You have a family history of liver disease
  • You have a history of gastrointestinal disease
  • You are taking medications which can harm your liver
  • You are a heavy drinker
  • You take performance enhancing drugs

Summary of Biomarkers

What are liver enzymes?

Liver enzymes are proteins that speed up chemical reactions in the body. Damage or poor functioning of the liver can cause elevated liver enzymes in the bloodstream.

ALT, ALP, AST, & GammaGT

Alanine aminotransferase (ALT), alkaline phosphatase (ALP), and aspartate aminotransferase (AST) are enzymes found primarily in the liver. Generally, ALT, ALP, and AST levels in the blood are low. However, damage to the liver can cause these enzymes to leak from the liver into the bloodstream, elevating blood liver enzyme levels. The same is true for GammaGT. High levels of GammaGT in the blood can be a sign of liver or bile duct damage.


Bilirubin is an orange-yellow substance that is created during the normal breakdown of red blood cells. Bilirubin passes through the liver before being excreted from the body. Elevated levels of bilirubin can indicate liver or bile duct problems. Too much bilirubin in the bloodstream can cause jaundice, which causes the eyes and skin to turn yellow.



Elevated liver enzymes may not produce any symptoms. However, if liver damage or disorder is the cause, symptoms may include:

  • Abdominal Pain
  • Dark Urine
  • Jaundice (yellowing of the skin or eyes)
  • Loss of appetite
  • Fatigue
  • Itching
  • Nausea and vomiting
  • Weight loss
  • Diarrhea


How soon will I receive my test results?

Once you have collected your sample and then mailed it to our laboratory, it generally takes a few working days before you receive the test result. As soon as your test sample arrives at the laboratory you will receive a notification by email. Once your test result is ready, you will receive a text message and an email from us with a link to your test result. We will therefore keep you well informed throughout the entire testing process!

What does the result of this test mean?

This test measures the liver enzymes ALT, AST, GammaGT, ALP, and bilirubin levels in your blood. Based on the test result, it can be determined whether there are abnormal levels of certain liver enzymes and whether follow-up care is needed with a GP.

Frequently asked questions

How accurate is this at home liver test?

The blood test is comparable in quality and accuracy to a test that you would receive in a clinic or hospital.

Can you test your liver function from home?

Yes, you can take this liver function test from the comfort of your home. You will receive an easy-to-use at-home collection kit that includes everything you need for collecting a sample and sending it to one of our ISO 15189 certified laboratories.

Can the liver repair itself?

The liver is an organ which is constantly in a state of regeneration. The moment it stops processing for example alcohol, it begins the process of healing itself. This process could take as few as four weeks or as long as several years.

What can I do to keep my liver healthy?

There are many ways to keep your liver healthy, but it starts with taking the following steps;

  • Eat a balanced diet
  • Maintain a healthy weight
  • Use alcohol responsibly
  • Exercise regularly
  • Avoid the use of drugs as much as possible
What is the average age for liver disease?

Liver disease usually develops in people between the ages of 40 and 50 years old, but can develop in younger people as well. The body will be able to compensate for the liver’s limited function in the early stages of the disease, but as the disease progresses symptoms will worsen and become more noticeable.

What increases my risk of liver disease?
  • Heavy alcohol consumption
  • Type II diabetes
  • Obesity
  • Family history of liver disease
  • Risk factors for hepatitis (exposure to other people’s blood/bodily fluids, unprotected sex)
Do elevated liver enzymes always indicate liver damage?

In most cases, elevated liver enzymes are temporary and do not indicate a chronic, serious liver problem. The cause of elevated liver enzymes should be further investigated by a GP, as there can be many different causes.

Can you reverse liver damage?

Some liver problems can be treated or reversed. However, treatment depends on the cause of the diagnosis. Please consult your GP for more information on treatment.

What can cause elevated liver enzymes?

Elevated liver enzymes can occur for many different reasons, and do not always indicate a chronic, serious liver problem. Common causes of elevated liver enzymes include:

  • Use of over the counter pain medications
  • Other prescription medications
  • Hepatitis
  • Alcohol or drug use disorder
  • Cirrhosis
  • Metabolic syndrome
  • Celiac disease
  • Liver cancer
  • Mononucleosis
  • Epstein-Barr Virus
