What is the normal value of serum total bilirubin

Hello, serum total bilirubin is a very important item in the liver function test, serum total bilirubin serum total bilirubin higher than normal value is mostly due to liver damage, liver function metabolism is not normal.

The determination of serum total bilirubin is an important test item in liver and biliary function tests. It can accurately reflect the degree of jaundice and is of great significance for the clinical diagnosis of occult jaundice.

1.Physiological elevation: Physiological jaundice occurs in newborns, but there is no other discomfort, and it will resolve spontaneously after about a week.

Long-term alcohol consumption and strenuous exercise may also cause an increase in total bilirubin. High total bilirubin due to physiologic causes usually resolves spontaneously after regulation.

2.Pathological elevation: common in hepatitis, obstructive jaundice, liver cirrhosis, neonatal pathological jaundice, cholelithiasis, pancreatic head cancer, hemolytic jaundice and other diseases.

Patients should pay great attention to it, go to the hospital in time, seize the best opportunity, grasp the development trend of the disease, detect the development and changes of the disease, and have a comprehensive understanding of their own condition.

High total bilirubin is generally caused by problems in the liver and bile ducts, and for total bilirubin itself, simply high levels will not cause the problem of infection. However, if the total bilirubin is high and is caused by viral lesions in the liver, then it is necessary to pay attention because hepatitis is contagious. If the bilirubin is high due to other non-communicable diseases, there is no contagion.

This needs to be determined on a case-by-case basis based on the results of the examination.

Beauty and maternity knowledge.

1 Total bilirubin:

Bilirubin is a pigment in human bile, orange-yellow, it belongs to the main metabolite of iron porphyrin compounds in the body, is toxic, irreversible damage to the human brain and nervous system, but also has antioxidant function, can inhibit the oxidation of linoleic acid and phospholipids.

The determination of total bilirubin in serum is an important indicator of liver and bile function testing, which can accurately reflect the degree of jaundice and is of great significance for the clinical diagnosis of occult jaundice.

2. The normal value of direct bilirubin in infants is 0 6 8mol l or less;

Normal values for indirect bilirubin are the following;

The normal value of total bilirubin is 3 4 17 1mol l.

Generally speaking, the phenomenon of physiological jaundice will occur in newborns, about 2 days after birth, ** begins to turn yellow, reaches a peak in 3-5 days, and disappears in about 7-10 days. At this stage, total bilirubin generally does not exceed 15 mg dl.

1.Jaundice is detected within 24 hours of birth in newborns, and is known as "early-onset jaundice".

2.The jaundice index rises too high all of a sudden, increasing by more than 5mg dl a day, which is more common as hemolytic jaundice (the blood type of the mother and baby is incompatible).

3.The jaundice index rises too high, with 15mg dl.

4.If it lasts too long, the general physiological jaundice lasts for 7-10 days, if it is more than 2 weeks, you should pay attention.

3 Direct bilirubin: 0

Direct bilirubin is produced by the combination of indirect bilirubin into the liver by the action of intrahepatic glucuronosyltransferase and glucuronic acid.

When direct bilirubin is elevated, it may be caused by diseases such as obstructive jaundice, hepatocellular jaundice, liver cancer, pancreatic head cancer, cholelithiasis, and cholangiocarcinoma.

4 Indirect bilirubin: 0

Indirect bilirubin is also known as unconjugated bilirubin, i.e., bilirubin that does not bind to glucuronic acid.

Certain malignant diseases can also cause high indirect bilirubin in finch blood, such as acute jaundice hepatitis, acute liver necrosis, chronic active hepatitis, liver cirrhosis, etc.

When a large number of red blood cells are destroyed in the human body, and there is too much indirect bilirubin in the blood, it exceeds the transformation ability of the liver, so that the indirect bilirubin is retained in the blood, which causes the indirect bilirubin in the blood to be high, which is also called hemolytic jaundice.

When blood with incompatible blood is transfused, it will cause hemolysis, which will destroy a large number of red blood cells in the body, resulting in high indirect bilirubin in the blood.

When liver cells are diseased, or because bilirubin cannot be converted into bile normally, or because the liver is thin and empty sensitive cells are swollen, the bile ducts in the liver are compressed, the excretion of bile is blocked, and the bilirubin in the blood is increased.

Severe scalding, sepsis, malaria, hypersplenism, pernicious anemia, globin dysgenesis anemia, lead poisoning, neonatal physiological jaundice, drug-induced jaundice, constitutional jaundice, mammalian jaundice, etc.

1 Total bilirubin includes direct bilirubin and indirect bilirubin, which both belong to the classification of bilirubin, which is a kind of bile pigment, which is the main pigment in human bile and is orange. They are toxic, can cause damage to the nervous system and brain, and also have antioxidant effects, which can inhibit the oxidation of linoleic acid and phospholipids.

23 Jaundice refers to the phenomenon of yellow staining of tissues such as sclera and mucous membranes caused by hyperbilirubinemia.

At that time, jaundice that is difficult to observe with the naked eye appears as occult jaundice or subclinical jaundice.

2.When TBIL is greater than that, it is a dominant jaundice aberration.

Overt jaundice can be divided into mild, middle-brother, and severe.

1.Mild jaundice: TBIL is in between.

2.Moderate jaundice: TBIL between 171-342 mol l.

3.Severe jaundice: TBIL above 342 mol L.

1.The increase in total bilirubin and indirect bilirubin is hemolytic jaundice, which is seen in severe large-scale burns, hemolytic anemia, etc.

2.Elevations in total and direct bilirubin are seen in obstructive jaundice, such as cholelithiasis and tumor compression.

3.Elevations of total bilirubin, direct bilirubin, and indirect bilirubin are stem cell jaundice, which is seen in viral hepatitis.

4. The decrease in total bilirubin is seen in microcytic hypochromic anemia, blood diseases, cachexia, etc.

Question 1: How much is the total bilirubin higher than abnormal Serum total bilirubin and conjugated bilirubin determination [normal reference value] serum total bilirubin serum conjugated bilirubin serum total bilirubin (STB) 17 34 mol l is recessive jaundice; 4 170 mol l for mild jaundice; 170 340 mol l for moderate jaundice; 340 mol l is severe jaundice.

Question 2: Is my total bilirubin much higher? But it is normal for me to do a B-ultrasound examination, so what is the reason?

Is there any way to do it OK. You have a very poor mental quality. If you believe in modern medicine, you don't have to worry about these situations at all.

Now you should:

Check for high aminotransferases. and symptomatic**. If the aminotransferases are normal and the simple bilirubin is high, it doesn't matter, usually pay attention to the conditioning, and the conditioning method is searched on the Internet: how to regulate the high bilirubin.

Question 3: How much is the total bilirubin high The results of this test are high in total bilirubin and indirect bilirubin.

Direct bilirubin]0

Indirect bilirubin 0 20 mol

It is generally believed that exceeding the normal range is abnormal, and the severity of the disease needs to be determined in combination with clinical symptoms.

2010-03-06 17:17:05 I want to complain.

This test value is slightly higher for total bilirubin and indirect bilirubin, due to ** jaundice that is considered for neonatal hemolytic jaundice.

There is no specific value to determine how high it is, but it should be determined in combination with clinical symptoms.

Question 4: How much is the total bilirubin higher than normal Hello, hello, bilirubin has total bilirubin, combined with bilirubin, free bilirubin and other indicators, generally normal, the total bilirubin does not exceed.

Question 5: Is it abnormal that the total bilirubin is too high, what should I do, the simple bilirubin is high, everything else is normal, it may be an error in the test, and it will not affect the civil service examination!

You are Xiao Sanyang, if you are not contagious, it should not affect the recruitment of civil servants.

Question 6: How much is the high bilirubin in the physical examination of civil servants considered abnormal Physical examination standards for civil servants (trial).

Article 7 All kinds of acute and chronic hepatitis are not qualified. Hepatitis B pathogen carriers, who are excluded from hepatitis after examination, are qualified.

That is, the condition is not serious, has not yet developed into hepatitis, and is qualified.

It is recommended to consult a doctor at a regular hospital.
