Liver Function Test

About this test

What This Test Measures

The GetTested Liver Function Test measures several key biomarkers, including ALT, AST, bilirubin, and albumin.

These markers provide a clear overview of liver-related biomarkers and can help you understand changes in these levels over time.

Key Biomarkers Analyzed

This panel measures four liver-related biomarkers:

• Alanine Aminotransferase (ALT): An enzyme found mostly in the liver and also present in other tissues.

• Aspartate Aminotransferase (AST): An enzyme found in the liver, muscles, and other tissues.

• Bilirubin: A substance formed during the normal breakdown of red blood cells.

• Albumin: A protein produced by the liver that helps transport substances in the blood and support fluid balance.

Together, these markers provide a broader view of liver-related biomarker levels.

About Liver-Related Biomarkers

The liver is involved in many normal body processes, including nutrient processing, protein production, bile production, and the processing of certain substances.

Measuring liver-related biomarkers can help support:

• A baseline view of selected liver-related markers

• Tracking of biomarker values over time

• Reference range comparison from laboratory analysis

• More informed discussions with a healthcare provider

Who This Test Is For

This test may be suitable for adults who want to measure selected liver-related biomarkers using home sample collection and laboratory analysis. It may also be useful for people who regularly track personal health markers and prefer secure digital results without visiting a clinic.

• Individuals interested in monitoring liver-related biomarkers over time

• Those tracking changes in internal health markers as part of general health awareness

• People looking for a convenient at-home testing option

• Individuals who prefer private testing without visiting a clinic

• Those who regularly track personal health data

Ideal for routine monitoring and ongoing awareness of liver-related biomarkers.

Biomarkers included

• Bilirubin: Bilirubin is a yellow pigment formed when red blood cells are broken down. It is transported to the liver, where it is processed (conjugated) and then excreted through bile. Measuring bilirubin helps assess how well the liver and bile flow pathways are functioning. Elevated levels may be seen with liver or bile duct problems (such as impaired bile flow) or with increased breakdown of red blood cel
• Alanine Aminotransferase (ALT): Alanine aminotransferase (ALT) is an enzyme found mainly in liver cells. When liver cells are stressed or damaged, ALT can leak into the bloodstream, which is why it’s commonly used as a marker of liver health. Elevated ALT levels may indicate liver inflammation or injury and are seen in a range of conditions affecting the liver. ALT is typically interpreted together with other liver-related marke
• Albumin: Albumin is the most abundant protein in blood plasma and is produced by the liver. It helps maintain oncotic (osmotic) pressure, keeping fluid within the bloodstream, and it also transports many substances such as hormones, fatty acids, and certain medications. Measuring albumin can provide useful information about liver synthetic function and overall protein status. Abnormal levels may be seen in
• Aspartate Aminotransferase (AST): Aspartate aminotransferase (AST) is an enzyme found in several tissues, including the liver, heart, skeletal muscle, kidneys, and red blood cells. It is involved in amino acid metabolism and can be released into the bloodstream when cells in these tissues are stressed or damaged. Elevated AST may indicate liver injury, but because AST is not liver-specific, increased levels can also be seen with m

How to prepare

We recommend collecting your blood sample in the morning after an overnight fast (no food or drink except water).
