How to judge the condition of jaundice from the bilirubin value? Bilirubin is the waste after the heme metabolism of red blood cells in the blood. If the serum bilirubin is too high, it indicates abnormal information such as liver disease or bile duct obstruction. The value of serum bilirubin represents the severity of the abnormality.
Netizen consultation: some time ago and the company to do the relevant physical examination, but in the bilirubin value I compared with other colleagues in the company have a big difference, very worried, but I will not see. So, how to analyze the bilirubin detection value?
Bilirubin (bilirubin) is a kind of bile pigment, it is the main pigment in human bile, orange yellow. It is the main metabolite of iron porphyrins in the body, toxic, can cause irreversible damage to the brain and nervous system, but also has antioxidant function, can inhibit the oxidation of linoleic acid and phospholipid. Bilirubin is not only an important basis for clinical diagnosis of jaundice, but also an important indicator of liver function.
So how to analyze the bilirubin detection value?
Bilirubin includes total bilirubin, direct bilirubin and indirect bilirubin. The normal value of total bilirubin is 5.1-19.0 & mu; mol / L, the normal value of direct bilirubin is 1.7-6.8 & mu; mol / L, and the normal value of serum indirect bilirubin is 3.4-12 & mu; mol / L. If the serum bilirubin is too high, it often reveals abnormal information such as liver lesions and bile duct obstruction.
Bilirubin is an important index to judge the type and degree of jaundice
Generally speaking, jaundice less than 34 & mu; mol / L is difficult to be detected by visual inspection, which is called recessive jaundice. 34-170 pmol / L for mild jaundice, 170-340 & mu; mol / L for moderate jaundice, & gt; 340 & mu; mol / L for high jaundice, 340-510 & mu; mol / L for complete obstructive jaundice, 170-265 & mu; mol / L for incomplete obstructive jaundice, generally & lt; 85 & Mu; mol / L for hemolytic jaundice, generally & lt; 200 & mu; mol / L for hepatocellular jaundice, 35% for direct bilirubin / total bilirubin, and generally & gt; 3400 & mu; for obstructive jaundice; The ratio of direct bilirubin to total bilirubin was 60%.
