Why Are Liver Function Tests Important?
The liver is among the most important organs of your body. It processes all the food you consume and drink as well as inhale. It eliminates toxic substances, makes bile and assists in regulating the blood sugar level. This is why tests for liver function are crucial - they help to identify liver issues early.
Like any organ, the liver is also prone to be affected as time passes. If you conduct regular tests for liver function to monitor your liver's health and spot problems before they become worse. A quick detection of liver problems could be crucial to successful treatment. This includes modifications to your lifestyle, medication or even the possibility of a transplant of your liver when needed.
Common Types of Liver Function Tests
Blood tests in the liver can detect different substances present in blood. Here are a few of the most popular tests:
1. ALT (Alanine Aminotransferase)
This enzyme is found in the liver and it assists in converting protein into fuel for the liver cell. The presence of high levels of ALT in blood may be a sign of liver damage.
2. AST (Aspartate Aminotransferase)
AST is an enzyme that is found in the liver, as well as other organs such as muscle and the heart. Similar to ALT high levels may be a sign of liver damage, however, AST is more specifically related to liver issues than ALT.
3. Bilirubin
Bilirubin is a waste product the liver uses to process. In high amounts of bilirubin the blood can cause jaundice. This is where your eyes and skin change color to yellow. The elevated levels of bilirubin could indicate liver problems or bile duct issues.
4. Alkaline Phosphatase (ALP)
ALP is an enzyme that can be found in the bones, liver and the bile drains. ALP levels that are elevated ALP levels could indicate problems with bile flow or bone disease.
5. Albumin and Total Protein
The production of these proteins is done in the liver. The low levels of albumin could suggest a problem with liver function, since the liver is the primary source of our body's albumin.
6. GGT (Gamma-Glutamyl Transferase)
GGT can be described as an enzyme which aids to break down proteins. It can be found within the liver. The presence of elevated levels of GGT could indicate liver issues or damage to the bile duct.
What Do the Results of Liver Tests Indicate?
The results of tests for liver function can aid doctors in determining the health of your liver correctly or if you have evidence of damage to your liver. Here's a quick overview of what results may reveal:
Results that are normal: Suggest that your liver is in good shape.
The liver has high levels of enzymes (e.g. the ALT or (e.g., AST,): This may be a sign of liver damage or inflammation.
Bilirubin levels that are high: Could point to liver problems or issues with bile ducts.
Low levels of albumin It could indicate damage to your liver because your liver is the one that produces albumin.
If one of these results is abnormal, your physician may recommend further tests or imaging to obtain an accurate picture of the health of your liver.
Understanding ALT (Alanine Aminotransferase)
ALT is a vital indicator of the health of the liver. If the liver cells suffer damage, ALT gets released in the bloodstream which causes an increase in its levels. For instance, issues such as hepatitis or fat liver disease, as well as alcohol-related liver damages may result in an rise of ALT levels.
The greater the ALT the greater chance the liver may be in stress. However, keep in mind that ALT is only one of many tests and your doctor will take a look at the whole image of your liver's health.
AST (Aspartate Aminotransferase) Test
As ALT, AST is an enzyme that can indicate liver damage when levels are high. But, AST is found in other organs, too like muscles and the heart. So, excessive AST levels don't necessarily mean the liver is the problem. For a more precise diagnosis, doctors will often check those levels ALT in addition to AST.
Bilirubin Test: What Does It Tell You?
Bilirubin is a chemical created when your body is breaking down the red blood cells. If your liver isn't working correctly, it might not be able to process bilirubin properly which can lead to the accumulation of blood. This can lead to jaundice where the eyes and skin change color to yellow. The elevated levels of bilirubin could indicate cirrhosis, or obstructions to the bile duct.
Alkaline Phosphatase (ALP) Test
The ALP test determines the amount of an enzyme which is crucial in the liver's capacity to process the bile. If the flow of bile is restricted and the organs are damaged ALP amounts can increase. ALP levels that are high ALP levels could signal liver problems such as the bile duct blockage or cholestasis.
Albumin and Total Protein Test
Albumin is a protein made by the liver, which helps to maintain a healthy fluid balance within the body. Insufficient levels of albumin could be a sign of liver disease. Similar to the total protein levels, which are a measure of all blood proteins will help determine the ability of the liver to make essential proteins.
GGT (Gamma-Glutamyl Transferase) Test
GGT is a second enzyme that may signal liver issues, particularly when bile duct or alcohol problems are involved. The highest levels of GGT are typically observed in those who drink alcohol in excess or suffer from diseases that affect the bile ducts.
When Are Liver Function Tests Done?
Liver function tests are generally performed during regular health checks in particular if you're suffering from the risk factors for developing liver disease. The doctor can also request tests if you exhibit symptoms that include:
jaundice (yellowing of the eyes and skin)
Abdominal pain
The abdomen is swelling, or in the legs
Unknown cause of fatigue
Dark urine or pale stool
In the event that any of these signs are present it's crucial to seek medical attention as soon as you can.
What Happens If Liver Function Tests Are Abnormal?
If tests of your liver function have irregular results, this does not necessarily mean that you suffer from a serious liver issue. There are many things that can impact the liver's function, such as alcohol, medications or even temporary illness.
Your doctor might suggest further tests, including one of the tests, an ultrasound CT test, or biopsy, to gain more information about the cause. Based on the type of diagnosis, treatment options can range from lifestyle adjustments (like cutting down on alcohol consumption or loss of weight) to medication or liver transplants in the case of severe damage.
How to Prepare for Liver Function Tests?
