Liver function tests are essential for evaluating liver health, diagnosing liver diseases, monitoring  ongoing conditions, and assessing overall organ function. Interpretation of these results should be done  by a healthcare professional in the context of an individual's medical history and other diagnostic  findings. 

Experts recommend screening tests for people who are at higher risk of the disease. This includes people  with diabetes or high blood pressure. If you have diabetes, your doctor may recommend checking your  kidney function yearly. This is often done with blood and urine tests.
