Liver Test

The liver is an amazing organ that serves many purposes:
*Detoxification of the blood
*Producing clotting factor and other important proteins
* Metabolizing medications and nutrients
*Processing waste products of hemoglobin
* Storing vitamins, fat, cholesterol, and bile
* Produces glucose
Blood tests for the liver are some of the most common tests ordered by Physicians. These tests are used to determine the presence of certain enzymes that can indicate damage. Normally these enzymes reside within the cells of the liver, but when the liver is injured, these enzymes spill out into the blood stream. Mostly the liver tests look for things called ‘aminotransferases’ these are called: ALT, and AST. When these test levels are elevated, there can be a variety of causes. For example, you may have a high reading for your ALT/AST if you have muscle damage. Elevated levels do not always indicate liver disease.
Interpretations of these levels must be done after taking all clinical history and lab reports into consideration, a task that your doctor can accomplish best. It is important to note that elevated AST/ALT are not actually for indicating function of the liver, but are used to detect inflammation in the liver from any source.
A simple LFT or ‘liver function test’ is ordered routinely by Doctors and will more than likely be a part of your next physical. Optimal health requires routine screening of all body systems, including the liver.
