Normal ranges for Liver Function Test can vary based on age, gender, and the laboratory performing the test. Your doctor interprets the results in the context of your overall health. Values slightly outside the normal range may not always indicate a problem, so always discuss results with your doctor.

When reading your Liver Function Test results, look at each parameter and compare it with the reference range provided by the lab. Values marked as 'H' (high) or 'L' (low) need attention. However, a single abnormal value doesn't necessarily mean disease. Your doctor considers the complete picture.
