Things To Take Note During Blood Tests for Liver Function

The tricky thing about blood tests for your liver function is that it doesn’t accurately reflect your liver’s condition since what it detects is only a damage to the liver. This means that mild liver disease might go undetected.

Even if your blood test result shows normal readings, it might be possible that slight abnormality on your liver function is not reflected.

This is why image tests are very important. Image tests like ultrasound, CAT, and MRI scans are more sensitive and detailed and have the ability to detect the level of liver disease. Tumors, gallstones and cysts can also be detected making it easier to preempt possible liver complications in the future.

Good news is, we can always do something to keep ourselves away from abnormal liver functions. With proper diet, achieving a healthy liver is as easy as pie.

Today, we’ll look into important things to take note during routine blood tests. An automated channel analyser will check the blood levels of the following components:


This test will measure the amount of bile pigment present in the blood. One indication that a patient has a high level of bilirubin is the yellowish color of their skin and eyes. Normal range for bilirubin level is 2-20 umol/L or 0.174 to 1.04 mg/dL

Liver Enzymes

Liver enzymes include AST (aspartate aminotransferase), ALT (alanine aminotransferase), ALP (alkaline phosphatase), and GGT (gamma glutamyl transpeptidase).

These enzymes are normally found inside liver cells which only leak to our bloodstream once the liver cells are damaged just like in the case of a liver disease. This is why testing liver enzymes will only yield results of liver damage and not really the general condition of your liver.

AST’s normal range is 0-45 U/L and can be elevated in heart and muscle diseases and is not liver specific.

ALT’s normal range is 0-45 U/L and is more specific for liver damage

ALP’s normal range is 30-120 U/L and is elevated in many kinds of liver disease but can also be higher on non-liver related diseases.

GGT’s normal range is 0-45 U/L and are usually found elevated to those who consume higher levels of alcohol and liver-toxic substances.

Blood Proteins

Blood proteins are manufactured by the liver and are measured in the blood test for liver function. Normal range is 60-80g/L or 6-8g/dL

Serum albumin

Measuring levels of serum albumin is a very helpful means to know how severe the chronic liver disease is. A healthy liver produces more albumins contrary to a deteriorating one which shows falling levels of blood albumin.  Normal range of blood albumin is 38-55g/L or 3.8 – 5.5 g/dL

Globulin protein

Elevated levels of globulin proteins in blood can be an indication of inflammation of immune system or and/or liver. Very high levels of this protein may be found in some types of cancer as well. Its normal range is 20-32 g/L or 2-3.g/dL

Be aware of your liver function and keep a healthy, balanced diet!
