Why Do Life Insurance Companies Check Liver Function?

Liver function testing is an essential component of life insurance blood tests because the liver plays a vital role in maintaining overall health. The liver performs numerous crucial functions, including:

  1. Detoxification: The liver helps in detoxifying harmful substances and metabolizing medications and drugs.
  2. Protein Production: It synthesizes proteins necessary for blood clotting, immune system function, and transportation of essential nutrients.
  3. Bile Production: The liver produces bile, which aids in digestion and the absorption of fats and fat-soluble vitamins.
  4. Carbohydrate Metabolism: The liver plays a role in regulating blood sugar levels by storing excess glucose as glycogen and converting it back to glucose when needed.
  5. Fat Metabolism: It processes and transports fats in the body, making them available for energy use.

Liver Function Tests in Life Insurance Blood Tests

Life insurance blood tests typically include several markers that help assess liver function. The most common liver function tests performed during these medical examinations include:

  • Alanine Aminotransferase (ALT): ALT is an enzyme found primarily in liver cells. Elevated ALT levels may indicate liver damage or injury, such as in cases of hepatitis or alcohol-related liver disease.
  • Aspartate Aminotransferase (AST): Like ALT, AST is also an enzyme found in the liver, as well as in other organs. Elevated AST levels can indicate liver damage or other conditions affecting the heart, muscles, or kidneys.
  • Alkaline Phosphatase (ALP): ALP is an enzyme present in the liver and bones. Increased ALP levels may suggest liver problems or bone disorders.
  • Gamma-Glutamyl Transferase (GGT): Elevated GGT levels may indicate liver disease or alcohol abuse.
  • Total Bilirubin: Bilirubin is a waste product formed when the liver breaks down old red blood cells. Abnormal levels may indicate liver dysfunction or other conditions affecting the blood.

Why Liver Function Testing Matters for Life Insurance Applicants?

The liver is a vital organ that impacts overall health and longevity. Liver diseases or abnormalities can significantly affect life expectancy, and insurance companies use liver function test results to assess an applicant’s health risks. Here’s why it matters:

  • Risk Assessment: Elevated liver enzymes may suggest underlying liver disease or other health issues. Insurance companies consider this information when determining an applicant’s insurability and calculating policy premiums.
  • Policy Eligibility: In some cases, significantly impaired liver function may result in a decline of the life insurance application. However, minor elevations in liver enzymes may not lead to an automatic denial but could impact the terms and pricing of the policy.
  • Identifying Health Concerns: Liver function tests can serve as an early warning for potential liver problems, allowing applicants to seek appropriate medical attention and make lifestyle changes that may improve their health.


Life insurance blood tests are an integral part of the underwriting process. They enable insurance firms to evaluate the health of applicants and establish the most suitable policy terms. These tests support the continued financial viability of life insurance plans for both the insurers and the policyholders by identifying underlying health issues and evaluating overall risk. If you’re thinking about applying for life insurance, be ready for a physical exam, which may include blood tests, and be open and truthful about your medical history. This will help the application process go more smoothly.
