Which test may be performed to assess liver function?

Liver function tests (LFTs) are specifically designed to evaluate the health and functioning of the liver. These tests measure the levels of various enzymes, proteins, and substances in the blood that are indicative of liver activity and overall liver health. For example, elevated levels of enzymes such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) can indicate liver damage or inflammation. Additionally, LFTs can help assess the liver's ability to produce proteins and process waste products.

In contrast, a complete blood count (CBC) is primarily used to assess overall blood health, measuring components such as red blood cells, white blood cells, and platelets, but it does not focus specifically on liver function. Blood glucose testing measures the level of glucose in the blood, which is relevant for diabetes management but not for assessing liver function. An electrocardiogram (ECG) is used to evaluate heart health and rhythm, and it does not provide information related to liver function. Hence, liver function tests are the appropriate choice for assessing liver health.
