Indirect bilirubin 21

When doctors diagnose a disease, they need to use multiple symptoms and test indicators. Therefore, many patients will be asked by doctors to do many tests. Some tests are done through blood tests. This is why patients are constantly having blood drawn and tested when they are treating the disease. Bilirubin is an indicator for diagnosing liver disease. Let’s understand what indirect bilirubin 21 means.

1. What is the normal range of total bilirubin?

1. The normal range of total bilirubin is 1.71-17.1 μmol per liter of blood, of which direct bilirubin and indirect bilirubin are 1-4 mg/L and 1.7-10.2 μmol/L respectively. The normal value of total bilirubin in newborns will be slightly higher. The normal value of total bilirubin, the normal value of direct bilirubin and the normal value of indirect bilirubin are 3.4-17.1 μmol/l, 0-6.8 μmol/l and 1.7-10.2 μmol/l respectively.

2. High total bilirubin usually indicates problems with the liver and bile duct. As for the total bilirubin itself, simply being high will not cause any infectious problems. However, if the high total bilirubin is caused by viral liver disease, then you need to pay attention because hepatitis is contagious. If the high bilirubin level is caused by other non-infectious diseases, there will be no problem of infection. This requires a specific conclusion based on the inspection results.

2. Causes of high total bilirubin

The increase in total bilirubin is not caused by a simple reason. Generally, a series of problems in the body will lead to the increase in total bilirubin. This is also an alarm issued by poor health. The specific reasons for the increase are as follows:

1. Generally speaking, an increase in total bilirubin is caused by liver problems, such as acute or chronic icteric hepatitis, cirrhosis, or adverse reactions caused by blood type incompatibility during blood transfusion, or toxic hepatitis can also cause an increase in total bilirubin.

2. High bilirubin levels indirectly increase. Because the patient suffers from some hemolytic diseases, excessive damage to the red blood cells in the body will occur, causing an increase in total bilirubin. If there is a incompatibility between the blood types of the mother and the fetus during pregnancy, it will also lead to an increase in total bilirubin.

3. Direct increase in total bilirubin. If you suffer from cholelithiasis or liver cancer caused by obstruction of the bile duct, it will cause obstructive jaundice, which will directly lead to an increase in total bilirubin.
