what is alt level?
The normal level of ALT in the bloodstream is 5 to 45 U/L (units per liter). This range can slightly vary depending where you take the blood test. When a blood test shows elevated ALT levels outside the normal range, even a small amount, fatty liver and other liver disorders might be the cause. If the cause of the ALT enzyme level increase is due to a severe liver disease (like Cirrhosis), the levels would be higher than whatâs found in fatty livers patients. Please note that some labs name ALT as âAlanine Transaminaseâ, âAlanine Aminotransferaseâ or âSGPTâ.
