What is Considered High AST and ALT Levels?

?·?When values of aspartate aminotransferase (AST) exceed times the upper limit of reference, hepatic ischemia or hypoxia and toxic or pharmacological Estimated Reading Time: 4 mins. ?·?When your liver is damaged or inflamed, it can release ALT into your bloodstream. This causes your ALT levels to rise. A high ALT level can indicate a Author: Adrienne Santos-Longhurst.

The diagnosis of acute infection will be based on the presence of a clinical presentation of acute liver damage, the exclusion of other acute viral hepatitis and the presence of HCV RNA with anti-VH C negative or seroconversion of anti-HCV in 1 -3 months. The chronic hepatic lesion is usually asymptomatic or paucisymptomatic causing few symptoms and generates an elevation of aminotransferases less than 10 times the upper limit of reference.

Chronicity is defined by the persistence of the enzymatic elevation observed at least twice during a minimum period of 6 months. Therefore, the initial step what causes high ast and alt levels the diagnostic evaluation of mild or moderate hypertransaminasemia is the repetition of the analysis, which will confirm, if necessary, the existence of the abnormality and define it as chronic, and then the etiological evaluation will begin.

Some experts recommend, however, start the etiological study after confirming enzymatic elevation in a shorter period between 2 and 4 weeks.

The diagnostic systematics to be followed is usually structured in a sequence in which progress is made until the etiological diagnosis of hypertransaminasemia is obtained. However, the order of the steps to follow can be altered depending on the clinical context in which the finding of the analytical alteration occurs and the data provided by what is a good christian wife initial clinical history.

The initial clinical assessment should be aimed at identifying risk factors for viral chronic hepatitis previous transfusion of blood products, parenteral drug abuse, risky sexual behaviors, tattoos, piercing, etcexcessive alcohol consumption, treatment with potentially hepatotoxic drugs, family history of liver disease and associated diseases obesitydiabeteshyperlipidemia, autoimmune diseases, etc. Its diagnosis is based on the detection of anti-HCV antibodies by means of ELISA, so that in a patient with hypertransaminasemia and risk factors for HCV infection it is not necessary to use other confirmation techniques, however the viral RNA must be determined in how to play game online with friends by PCR in those cases in which it is valued to perform treatment and when it is necessary to confirm the diagnosis of active infection.

Excessive alcohol consumption is usually referred by the patient, but on many occasions it is minimized or hidden. In the diagnostic study of the patient with hypertransaminasemia is especially relevant to follow a pre-established system that allows determining with sufficient precision the cause, avoiding in turn, the performance of unnecessary examinations.

?·?Elevated liver enzymes often indicate inflammation or damage to cells in the liver. Inflamed or injured liver cells leak higher than normal amounts of certain chemicals, including liver enzymes, into the bloodstream, elevating liver enzymes on blood tests. The elevated liver . ?·?2. Alanine transaminase (ALT) It rises in case of liver damage. 3. Aspartate transaminase (AST) This enzyme gets elevated in the case of liver disease. 4. L-lactate dehydrogenase (LD) Its levels are raised in the case of liver disease. 5. Bilirubin. A high level of bilirubin may be due to liver damage. This results in jaundice. 6.

Aspartate transaminase AST is an enzyme important in the metabolism of amino acids. A test for serum blood AST is important in medical diagnosis, especially in conjunction with other enzyme blood tests. In particular, a test for alanine transaminase ALT in conjunction with AST can reveal the presence of liver disease, cardiovascular disease, and diseases of the skeletal muscles, as well as other conditions both benign and pathological.

When a blood test measures high AST , a wide range of possible causes exists. High AST can be caused by liver diseases, myocardial infarction heart attack , acute pancreatitis, acute hemolytic anemia , trauma especially severe burns , acute kidney failure , diseases of the muscular and skeletal systems, and other causes.

Sometimes the cause of the high AST result is obvious, e. Many of the causes are asymptomatic, however, such as liver diseases. Unless the cause is obvious, more diagnostic work is called for. When both the enzymes are elevated , a comparison of the two can provide information about the specific liver disease and its causes.

If ALT is elevated more than AST, this shows the presence of liver disease but suggests a non- alcoholic cause for the affliction. Alcohol abuse is the single most common cause of liver disease. Causes of liver disease other than alcohol abuse include obesity, type 2 diabetes, hereditary factors, side effects of medications, and viral and bacterial infections. Depending on the specific outcome of the enzyme tests, other diagnostic procedures may be called for. Medical imaging is a useful diagnostic tool.

If the tests indicate liver disease, an examination of the liver using ultrasound or computerized tomography CT scanning can show the presence of fatty deposits fatty liver disease , fibrotic scarring fibrosis , advanced scarring of the liver cirrhosis , inflammation and swelling hepatitis , or anomalous masses that may indicate either cancer of the liver or a non- cancerous tumor.

A liver biopsy can confirm or eliminate the presence of cancer and also be used to test for viral and bacterial infections. If the blood work indicates another cause for the elevated AST levels than liver disease, tests for heart problems, kidney functioning, and other diagnostic procedures related to the various non- liver causes of high AST are indicated.

Treatment for conditions causing elevated AST will depend, of course, on what the condition is. Recommendations can range from lifestyle changes diet, weight loss, cessation of drinking, exercise, changes in prescription medications to hospitalization and emergency trauma treatment or care for a heart attack or acute kidney failure. Although elevated AST can indicate severe and potentially life- threatening conditions, by itself it is not a cause for alarm.
