for all is not a secret that the liver in the human body is the most important because it performs many functions for the normal and uninterrupted operation of the whole organism.But when the body attacks the disease, a person must recognize them during - it is not hard to do, you can identify the signs of liver disease in the blood.
's no discovery is the fact that the liver performs many biochemical functions (the people that body is called "the body's natural filter").Due to the fact that in the body there is a set of complex biochemical reactions for proper liver function connects a huge amount of enzymes (they destroy all toxic substances that attack it).Therefore, their activity can be determined state of the organ as a whole.In order to prevent any time to identify the signs of disease, "the filter body" of man, you need to take a blood test.The blood test, experts estimate the performance of enzymes such as "aminotransferase" (they are indicated by AST, ALT).For men (under 40 years) normal rate
No less important indicator in a blood test that can help detect signs of liver disease, is a figure for "bilirubin" (this is the pigment in bile).Bilirubin is obtained by decomposition of the constituents of blood, primarily - hemoglobin and erythrocytes.In healthy people, it is formed in the spleen (popularly called the organ "depot") and then, in an aqueous state goes to the liver, and then released into the intestine with the bile.If a person has disrupted bile duct (liver both in and outside the body), interferes with the normal and timely return of bilirubin into the intestine that stimulates the release of it into the blood.Normal values of bilirubin in the blood (for both men and women) is from 3,5-20,2 mmol / l.Deviation from these indicators in the analysis may indicate that there are diseases of the biliary tract.
no less important factor in the blood is "albumin" (a blood protein that is produced in the liver).Albumin moves electrolytes and substances which are drugs, and also controls the pressure in the blood plasma.For men and women, this figure is the same.The norm of albumin in the blood is an indicator in the analysis of 35-50 g / l.If this figure is below the set standards, it may indicate that the disease in the body, there is not only the liver but also the kidneys.
Symptoms of liver disease may help identify the analysis of the blood indicators of liver enzymes, which is referred to as AST, ALT.Normal rate of content of such enzymes in the blood for a male and 40 U / l, and for the female - 30 U / L.If the analysis shows a higher level of such enzymes that fact may indicate signs of the disease such as onset of viral hepatitis or cirrhosis of the liver.If this figure is much higher than the established norm, most likely, the person there diseases associated with toxic damage of liver tissue.
also need to be addressed in terms of the analysis of blood levels of enzymes called "cholinesterase".For all people considered normal content of the enzyme at a level of 5300-12900 U / l.If the analysis of a decrease in the level of this enzyme, then, that fact may indicate the presence of such diseases as gallstone disease of the liver.Also, experts recommend a complete examination to cancer if the level holiensterazy significantly reduced.
In the study of blood tests, doctors also do not disregard the contents of the serum enzyme parameters "lactate dehydrogenase" (in the analysis is referred to as LDH).The enzyme in the human body has a plurality of functions.In order to detect signs of liver disease is indicated in the analysis of serum isoforms (the amount of serum 5) of this enzyme.Because, in the plasma itself, the concentration of LDH activity is lower than in serum.Normal values of LDH in serum is considered an indicator of 140-350 U / L.
If blood is present in the analysis of the increase in the concentration of isoforms of the enzyme LDH, then this may indicate signs of such diseases as acute hepatitis.Also, a sharp increase in the activity of the enzymes LDH may indicate that a person has a disease of the biliary tract with obstruction of the bile passages.
also recommended to pay attention to the analysis of blood levels of enzymes that are designated as "AP" (alkaline phosphatase).This enzyme is located in the cell membrane of bile ducts.These cells have small bristles which, if damaged, can not delay the AP, and as a result, the enzyme goes into the bloodstream.When a blood test is necessary to consider that for a healthy person, the normal rate of alkaline phosphatase is a record of 30-90 U / L.Exceptions to this rule are children in adolescence (up to 400 U / L) and a woman in a state of pregnancy (up to 250 U / L).In other cases, the increase in the concentration of the enzyme in the blood may indicate signs of the existence of such diseases as infectious hepatitis liver.
