I found this info :
An alanine aminotransferase (ALT) test is a blood test that measures the level of alanine aminotransferase enzyme found mainly in the liver, but also in smaller amounts in the kidneysVIEW IMAGE, heartVIEW IMAGE, muscles, and pancreasVIEW IMAGE. ALT formerly was called serum glutamic pyruvic transaminase (SGPT).
ALT is measured to determine whether the liver is damaged or diseased. Low levels of ALT are normally found in the blood. However, when the liver is damaged or diseased, it releases ALT into the bloodstream, causing levels of the enzyme to rise. Although ALT is found in organs other than the liver, most increases in ALT levels are due to liver damage.
on what is "normal",,,alt levels should be between 4–36 units per liter (U/L) or 4–36 international units per liter (IU/L)and
An aspartate aminotransferase (AST) test measures the amount of this enzyme in the blood. AST is normally found in red blood cells, liver, heart, muscle tissue, pancreas, and kidneys. AST formerly was called serum glutamic oxaloacetic transaminase (SGOT).
Low levels of AST are normally found in the blood. When body tissue or an organ such as the heart or liver is diseased or damaged, additional AST is released into the bloodstream. The amount of AST in the blood is directly related to the extent of the tissue damage. After severe damage, AST levels rise in 6 to 10 hours and remain high for about 4 days.
The AST test may be done at the same time as a test for alanine aminotransferase, or ALT. The ratio of AST to ALT sometimes can help determine whether the liver or another organ has been damaged. Both ALT and AST levels can test for liver damage.Normal is considered between
8–35 units per liter (U/L) or 5–40 international units per liter IU/L)
I hope this helps clarify it for you,,and if you want to email me i could give you a couple of links they may help you find info:) Hope you keep returning here,this is a wonderful site for support and a great place to vent if you need to. oh and one more thing,,id recommend your hubby seeing a hepatologist or GI SOON,,,it takes a while to get into some specialist so maybe you should call his dr and ask that they do a referral now,,good luck
