What does it mean if all five liver function tests are negative?

All five liver function tests are negative, indicating good health and no liver problems.

The "five liver function tests" refer to five indicators in a liver function panel: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, direct bilirubin, and albumin. When all five tests are negative, it generally means that the results for these five indicators fall within normal ranges, with no abnormalities detected.

Under normal conditions, the liver secretes various enzymes and proteins that help the body metabolize and digest food, as well as eliminate waste and toxins. If the liver is impaired, the secretion of these enzymes and proteins may be affected, leading to abnormal liver function test results. Therefore, if all five liver function tests are negative, this suggests normal liver function without significant abnormalities.

It should be noted that liver function tests only reflect certain basic aspects of liver health and do not provide a complete assessment of overall liver condition. For further evaluation or treatment, it is advisable to consult a qualified physician. In daily life, it's important to maintain healthy habits and avoid consuming excessive spicy or greasy foods.
