What is the normal range for alanine transaminase (ALT) levels?

  1. 1-30 IU/L

  2. 1-45 IU/L

  3. 46-100 IU/L

  4. 100-150 IU/L

The correct answer is: 1-45 IU/L

The normal range for alanine transaminase (ALT) levels typically falls between 1-45 IU/L. ALT is an enzyme primarily found in the liver, and its levels are important indicators of liver health. Elevated ALT levels can signify liver damage or inflammation, making it crucial for healthcare professionals to interpret these results in the context of other clinical findings. The chosen range of 1-45 IU/L reflects the commonly accepted reference values used in laboratory assessments. Values outside this range may lead healthcare providers to investigate further for potential liver conditions or other health concerns.
