What should the AST ALT ratio be for cirrhosis?
He found that the ratio decreased in patients with acute viral hepatitis and increased in patients with cirrhosis. The AST:ALT ratio in a healthy individual would be around 1.15. If the ratio is more than 2.0 (up to 6.0), this denotes alcoholic liver disease. And if the ratio is between 1.4 and 2.0, it suggests cirrhosis.
What should my AST and ALT levels be?
In a research study of 15 laboratory tests, it was shown that all acute viral hepatitis patients showed an AST level greater than 200 U/L and an ALT level greater than 300 U/L, which both are 25 times the upper limit of normal levels.
What does high AST mean on a blood test?
– Very high AST levels (> 1000 U/L) are most commonly due to viral hepatitis, ischemic hepatitis or liver injury due to drug or toxin. – Elevated AST in relation to ALT (i.e., AST/ALT ratio > 2), along with high GGT, can occur with alcoholic hepatitis. – Isolated AST elevation (without ALT elevation) may indicate cardiac or muscle disease.
What makes Alt non specific to the liver?
What are AST and ALT? Both AST and ALT are enzymes- proteins that accelerate chemical reactions. ASTis non-specific to the liver; this means it can be found in other organs of the body, and its levels can be elevated for a number of different reasons, such as a heart attack, acute pancreatitis or some infections, like mononucleosis.
What is the normal range for the AST blood test?
AST Blood Test Normal Range. Usually, the AST levels in the bloodstream are low. The normal values range of the AST blood test in males is 10 to 40 units per Liter of Serum and in females, it is 9 to 32 units per Liter of Serum.
How are AST and ALT levels related to liver disease?
In a research study of 15 laboratory tests, it was shown that all acute viral hepatitis patients showed an AST level greater than 200 U/L and an ALT level greater than 300 U/L, which both are 25 times the upper limit of normal levels. Are AST and ALT elevations always related to liver diseases?
What causes a high AST reading on a blood test?
It is also to be kept in mind that a higher level of these liver enzymes doesn’t necessarily be liver disease. Abnormal or high values of the AST blood test may be due to any reason like hepatitis, mononucleosis, cirrhosis, or any other liver diseases. Heart problems or pancreatitis can also be a reason behind the high values of AST tests.
How to find out your AST and ALT ratio?
Here’s an easy way to find out your AST:ALT ratio: divide your AST level as shown on your blood test results by your ALT level. For example, if your AST is 20 U/L and your ALT is 18 U/L, then your ALT ratio would be 1.05, which is within the normal range. What is the magnitude of AST and ALT elevations for acute viral hepatitis?
