Liver Function Tests

The Liver Basics!
As an Invite health nutritionist one of the most important parts of my job is to help people understand their blood work. In general I find that when it comes to blood work liver function tests tend to be some of the most confusing. But just what are the markers on your blood work that test for liver health? In other words what even is a liver function test? Well let’s get into this important topic, shall we?
Liver function’s tests are tests that are used to help monitor the health and function of the liver. The first test is ALT. This is an enzyme that is found in the liver. When the liver cell is damaged this enzyme is released and blood levels will increase. Another enzyme that is found in the liver is AST. AST is also found in muscle cells. If the levels are elevated it can indicate possible damage to either the liver or muscles. ALP is an enzyme found in both the liver and bones. If it is elevated in the blood it may indicate liver damage or disease. It may also indicate bone disease. In addition to testing enzymes that are active in the liver the liver blood tests also look at enzymes that are made by the liver. For example Albumin is a protein that helps to fight infection. Lower levels of albumin and even total protein may mean your liver isn’t healthy enough to produce them. Another job of the liver is to process Bilirubin. Normally this is passed through the liver and excreted in the stool. In certain types of liver disease this process is disrupted and bilirubin levels can increase in the blood. PT is a marker of how fast your blood is able to clot. Increased PT can indicate liver damage. However I just want to mention that certain medications can affect PT. Other tests can include GGT and LD. (1)
In addition to blood tests there are certain imaging tests that can help look for liver damage or disease. Imaging tests can include ultrasounds, CT scans or even getting an MRI. One test that can be important in monitoring liver health is a liver biopsy. (2)
These liver function tests may be abnormal for a number of reasons. For example you may have a virus, tumor, diabetes or other liver disease. (2) Throughout this series will be reviewing a number of these conditions. For example we will be reviewing disorders such as NASH, NAFLD, cirrhosis, and even hepatitis. We will also be talking about the gall bladder since it is so closely linked to the liver. Additionally in this series will be talking about how and when to detox. Lastly we will be talking about another important organ, our kidneys!
But what does the liver even do for our health? Well the liver has a number of important jobs. I’ve attached a picture detailing all the functions of the liver! Please take a look the attached picture. (3)
Since the liver is important for so many aspects of our overall health there are many studies on supplements that can help with liver health and function. Throughout this series we will be reviewing many of these nutrients. These nutrients include NAC (4), Milk Thistle (5), Dandelion (6), and even Catalase. (7) Other supplements that help fight infections that will be included will be nutrients such as Olive Leaf (8) and even Probiotics! (9) All of these important nutrients are available from Invite Health. I hope you find this topic as important as I do.
Our product highlight will be Glutathione lozenges!
