If you need to know which are the bilirubin reference ranges or you require more information about the role of bilirubin in the blood, you can visit normal bilirubin level in the blood
Hypobilirubinemia is not common and it is not an issue of concern. There are some labs that consider zero or not detected bilirubin level in the blood as normal value.
However, recent studies consider that there is a relationship between low serum bilirubin level and an increased risk of cardiovascular disease (angina pectoris, heart attack, etc.).
Total bilirubin blood values are usually given in mg/dl but sometimes you can see those values in µmol/l following the International System of Units (SI). In case your values are in µmol/l you can convert them using this tool:
The bilirubin value in the blood is a bit low but it is not a matter for concern.
If the calcium and phosphorus level in the blood are also low it can be a sign of bad intestinal lipid absorption.
There are some circumstances or drugs than can reduce your total bilirubin level in the blood:
Lower than normal level of total bilirubin in the blood can be due to:

The following values are considered to be below the normal range:
IMPORTANT: These levels are expressed in mg/dl. They are an example of a healthy man of about 45 years of age with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
The normal range in newborns for the first days of life differ from the following table. You must look for the applicable table for newborns.
