Liver Function Test – About, Normal Range, Preparation

Liver function tests are examinations of the liver chemistries to determine the levels of proteins, bilirubin, and enzymes in the blood work. Using these variables, medical professionals can draw up the liver enzymes level chart to pinpoint any possible threats or even to track the progression or initiation of diseases.

Doctors test your results against the liver functions and test normal values to determine if you have a higher or lower count on the liver enzymes level chart. These results help evaluate if there are any possible threats that could take effect on the liver.

Liver function test normal range is used as a parameter to not only check the health of your liver but also to screen the progression of serious, congenital, and chronic illnesses. Testing the enzyme levels against the liver functions test normal values is an excellent way to screen diseases such as hepatitis. It also helps track the effects or possible side effects of certain medications that are prescribed to you. They even help in tracking the severity of any preexisting or newly-developed liver disease.

Infections and diseases like Hepatitis can cause severe damage to the liver, especially in conditions where you may have been exposed to the hepatitis virus. Checking your charts against the liver function test normal range can help pinpoint issues in treatment or the progression of damage so the doctors can modify your course of treatment.

Why Do Doctors Recommend Getting A Liver Function Test?

As we have mentioned, checking your liver enzymes level chart against the normal AST levels is an excellent way to track certain diseases and the effects of medication. Liver function tests show the levels of healthy and unhealthy components that may protect or harm the liver and the degree to which the damage has taken effect.

Here are a few situations when doctors recommend getting a liver function test done to check your charts against the liver function test normal range:

  • To track the damage caused to the liver by diseases ad infections such as hepatitis C, hepatitis B, etc.
  • To check the effects of large quantities of alcohol on your liver functionality.
  • To track the effects of gallbladder disease on the functioning of your liver.
  • To monitor the effects and side effects of certain medications that have potentially stronger fallouts. If you are on Non-steroidal drugs, antibiotics, statins, medication for tuberculosis, and anti-seizure drugs, then checking your charts against the liver functions test normal values will provide a more accurate idea as to the condition of your liver.
  • To track the effects and progression of a liver disease that was preexistent.
  • Monitoring the formation and damage caused by new developments of liver diseases.
  • To check if you inherited any medical disorders associated with the liver based on the history of family health.
  • To track the developments of medical conditions such as diabetes, anemia, traces of high triglycerides, and problems related to high blood pressure.

 

If the levels of the liver function test normal range is a result then your liver may be showing signs of recovery or nonexistence of certain side effects. The deviation from normal AST levels shows possible causes of concern pertaining to liver damage.

What Is The Liver Function Test Normal Range?

When the liver functions test normal values are surpassed or the values of your test are lower than the normal range, then it is a reason for concern. Here are the liver function test normal ranges that you should aim for:

Alanine Transaminase (ALT)

ALT is secreted in your body as a means to metabolize protein. If the levels of ALT cross the liver function test normal range, chances are, the ALT is released into your blood. The liver functions test normal values for ALT in females is 25 units per liter and in males is 33 units per litre.

Aspartate Aminotransferase (AST)

ASTs are very important enzymes that are present in various parts of the body, particularly in your heart, liver, brain, pancreas, and muscles. If you suffer liver damage, the AST levels can release into the liver, thus deviating from the liver function test normal range.

Normal AST levels in the human body are 36 units per liter for adults. In children and teenagers, the levels may be slightly higher.

Alkaline Phosphatase (ALP)

ALPs are another form of important enzymes that are present in the liver, bile ducts, and bones. Testing the levels of ALP in your bloodstream helps determine the bile duct system in the liver and determine a possible need for treatment.

The liver function test normal range for ALP should be between 20 to 140 units per liter.

Albumin Test

Albumin is the component created by your liver to regulate the nourishment of tissues, transport hormones, vitamins, and several other substances. This protein is crucial and an albumin test tracks how well your liver is able to synthesize this protein.

The liver function test normal range for albumin is 35-50 grams per litre.

Bilirubin Test

Bilirubin is the wasteful byproduct of breaking down red blood cells that pass through the liver before leaving the body through the stool. The liver function test normal range for bilirubin is 0.1 to 1.2 milligrams per deciliter.

Preparation Methods For The Liver Function Test

In order to conduct the liver functions test to determine accurate values in the liver enzymes level chart, you need to prepare in advance for the procedure. Here’s how you prepare for a liver function test as directed by your health professionals:

  • Avoid eating certain items of food that influence the levels of enzymes and normal AST levels in the body.
  • Cut back on certain medications as per the doctor’s instructions a few days or hours before the test.
  • Avoid eating altogether before conducting targeted tests.
  • Drinking water up until the test.

 

Health professionals will need to collect a blood sample to create your body’s liver enzymes level chart to create the liver enzymes level chart. If the liver function test normal ranges are slightly above or below your own levels, then it is not a cause for serious concern. If the charts deviate significantly, it indicates liver damage.
