Liver enzymes ast and alt

AST and ALT (aminotransferase), AST and ALT are known collectively as transaminases. Are associated with inflammation and / or damage to liver cells, a condition known as hepatocellular liver injury. Liver damage, usually by a leakage of ALT and AST into the bloodstream. Since AST is found in many other organs, with the exception of the liver, kidney, including muscle and heart, which show a high level of AST is not always (often) that liver. For example, that vigorous exercise also raise AST levels in the body. On the other hand, because ALT is mainly in the liver, high levels of ALT were almost always show that there is a problem with your liver. Recognize Despite what one can expect a high level of transaminases in the blood is not always how badly the liver is inflamed or damaged. This is a very important point to remember. Normal range for AST and ALT are by 0 to 40 IU / L and 0 to 45 U / l, respectively. (IU / L stands for international units per liter and is most commonly accepted way to measure these specific enzymes.) The reason is that these blood tests measure inflammation and liver damage in rare moment. For example, if the inflammation of the liver in the day, which was created in the blood, we say, if the patient consumed alcoholic beverages produced a few hours before blood transaminase levels are exceeded, much higher than if the alcohol was consumed. Replace other issues there are many other factors, in addition to liver damage, which could affect the values of AST and ALT. For example, men have transaminases higher than in women. A, African-American men have a higher AST with Caucasian men. Even the time of the day, blood sampling may influence the level of aminotransferase. People seem to higher levels of transaminases in the morning and afternoon to night have. Thus, a level not significantly during the fasting and non-ver-fasting. Finally, the level of transaminases may differ day to day. The ratio of ALT and AST may also provide useful information about the extent and causes of liver disease. Most liver diseases are characterized by a rise in ALT to more than the increase in AST.

Liver enzymes normal range

Background / Aims: Hepatitis B virus (HBV) DNA was found HBsAg-negative patients with hepatitis C. We have the speed and explored the clinical significance of HBsAg-negative HBV coinfection in Austrian patients with chronic hepatitis C.

How liver enzymes normal range looks on hepatitis patients?

Methods: Sera (n = 82, group I) or liver tissue (n = 16, group II) of 98 HBsAg negative Austrian patients with chronic hepatitis C were HBV-DNA nested polymerase chain reaction (PCR) study. For control purposes, sera were examined 15 patients with chronic HBV infection (HBsAg positive 8, 7 HBsAg negative, all positive HBV-PCR).

Results: HBV DNA was detected in 22% and 19% sera samples of liver tissue in patients with chronic hepatitis C, no significant difference in mean aminotransferase, HBV infection, inflammatory disease activity or the degree of liver fibrosis in patients with or without HBV DNA observed. Anti-HBc as only marker of past HBV infection was more common in patients with chronic hepatitis C compared to control individuals.

Negative HCV PCR was more frequent (p = 0.009) in patients with positive PCR in serum HBV. In examining the repeat serum HBV DNA were found positive results in the past, negative, but negative results so far achieved positive patients.
