Bilirubin is a breakdown product that is produced when the hemoglobin in red blood cells is broken down and is measured to check the health of your liver.
Bilirubin is yellow in color
Bilirubin is a breakdown product. High levels of bilirubin can indicate that your liver is not functioning properly.
Brief about bilirubin
- Bilirubin gives stool and urine their color.
- Bilirubin is a breakdown product.
- High levels can indicate that the liver is not functioning properly.
P-Bilirubin
Bilirubin is a breakdown product (waste product) produced when hemoglobin in red blood cells is broken down. A bilirubin blood test is used to check the health of your liver.
High levels of bilirubin can indicate that your liver is not functioning properly. It can also be a sign of hemolytic anemia, which means that the body is destroying red blood cells faster than they are produced. Bilirubin levels may increase in connection with blood transfusion, hepatitis, cirrhosis, metastases, various inflammations, surgical injuries, liver tumors, and cell damage.
Low levels of bilirubin rarely have medical significance.
An out-of-range result does not always mean that you have a medical condition requiring treatment. An elevated value may also be due to the time of day the test is taken (the value can be twice as high in the morning as in the afternoon), medication, certain foods, or strenuous exercise. Your doctor will assess your levels in relation to other test results.
Bilirubin is yellow, which can be seen in the skin and whites of the eyes of people with jaundice who have very high levels of bilirubin in their blood. The yellow color also appears in old bruises that have turned yellow.
When might a bilirubin test be of interest?
- In the analysis of liver health
- In symptoms such as jaundice, dark urine, or abdominal pain
- To determine if there is blockage in the bile ducts
- To investigate any disorders related to problems breaking down red blood cells
To review your liver health, we recommend that bilirubin be supplemented with ASAT, ALAT, GT, and ALP.
Reference values for bilirubin
Women and men 18 years and older: <26 µmol/L
Reference values may vary depending on where the analysis is performed, and which analysis method is used.
ALAT – reference values and liver health
Alanine aminotransferase (ALAT) is an indicator of the well-being of the liver. It reacts to long-term alcohol use and fatty liver disease caused by excess weight, for example.
ALP (alkaline phosphatase) is an enzyme found in liver cells
ALP is the abbreviation for the enzyme alkaline phosphatase, which is primarily found in the liver, bile ducts, and bones. It is therefore common to measure ALP when examining the health of the liver, associated bile ducts, and skeleton.
ASAT, or aspartate aminotransferase, indicates the condition of the liver
High ASAT may indicate tissue damage in important organs.
GT is a liver enzyme that describes the health of the liver
GT is one of the standard tests used to assess the health of the liver and bile ducts, especially when there is suspicion of alcohol-related health issues. More GT is produced by liver cells when they are under stress, such as in liver diseases or heavy alcohol consumption.
LDL is a “bad” cholesterol
The LDL cholesterol level shows the amount of harmful cholesterol in the blood.
Monocytes are white blood cells
White blood cells are an important part of the human immune system. They protect the body from attacks of bacteria, viruses, and parasites. Bone marrow produces five different types of white blood cells, one of which is the monocyte.
