Normal bilirubin value for jaundice

Many newborns are born with jaundice, some of which are physiological and some are pathological. The one that needs to be identified is pathological jaundice. Bilirubin is very important for the identification of jaundice. Based on the jaundice test, we can have a preliminary understanding of the condition of the newborn. So, what is the normal bilirubin level for jaundice? Let’s take a look below.

The normal reference value of total bilirubin is: 3.42～20μmol/L.

If the total bilirubin level is elevated, it indicates that the liver is damaged. There is a certain correlation between the degree of increase in total bilirubin and the severity of jaundice. Generally speaking, the greater the increase in total bilirubin, the more severe the jaundice. If the increase in serum total bilirubin and indirect serum total bilirubin is mainly hemolytic jaundice, if the increase in serum total bilirubin and direct bilirubin is mainly obstructive jaundice, and if the increase in serum total bilirubin, direct bilirubin and indirect bilirubin are all increased, it is hepatocellular jaundice, such as viral hepatitis.

Therefore, when you find that your total bilirubin value is high, you must go to a regular professional hospital for comprehensive examination and treatment in time. If the total bilirubin is elevated due to various viral hepatitis, it is best for the patient to receive antiviral treatment.

Normal value of total bilirubin-clinical significance

It is mainly used clinically to diagnose liver disease and bile duct obstruction. When the total bilirubin exceeds the normal value, the human skin, sclera, urine and serum appear yellow, so it is called jaundice. Jaundice can be caused by inflammation, necrosis, poisoning and other damages to the liver. Biliary tract diseases and hemolytic diseases can also cause jaundice. Elevated direct bilirubin is common in primary biliary cirrhosis, biliary obstruction, etc. Elevated indirect bilirubin is common in hemolytic diseases, neonatal jaundice or blood transfusion errors. Both direct and indirect bilirubin can lead to cirrhosis and liver cancer.

Symptoms of high total bilirubin are most common in hepatitis patients. Therefore, when jaundice occurs, you should consider whether you are infected with hepatitis and go to the hospital for examination and diagnosis in time.
