The liver is one of the important and substantial organs of the body, with powerful functions such as excretion, synthesis, and secretion. The liver’s damaged function can be determined by the seven tests of liver function. The seven tests include lipase and total bilirubin, cholesterol, and bile acids.
There are reference ranges for the different tests, and the results can be compared to the reference ranges, and if they are higher or lower than the reference ranges, they indicate some impairment of liver function. For example, the transaminases in liver function tests reflect the degree of damage to the body’s liver cells, and if the value is too high, consider the risk of hepatitis; bilirubin is used to check the synthesis of the liver.
The seven liver function tests are based on drawing venous blood, so it is important to fast before the test to prevent food from affecting the test results.
If a liver test detects some disease in the liver, further testing is recommended, including abdominal ultrasound and MRI, because liver function tests cannot detect the presence of hepatitis B virus or liver cancer.
