upper limits for normal ALT to be as low as 30 U/L for males and 19 U/L for females. 3 In addition, ALT activity in patients with viral hepatitis, who achieved sustained virologic response, was often below 30 U/L.
The normal range for alanine transaminase (ALT) varies from laboratory to laboratory. One common reference range for an ALT blood test is 7 to 56 U/L (units per liter). ALT levels are typically higher in people assigned male at birth than in people assigned female at birth.
The normal upper levels of ALT are according to age and weight. Children (especially those below 18 months) typically have higher ALT levels. Also, males have higher average ALT levels than females.
ALT is the most specific enzyme to the liver itself. Typical ranges can vary between the sexes, based on age and at different laboratories. Generally speaking, the upper limit of typical for AST and ALT for men is 35 to 40 units per liter (U/L) and for women is 25 to 30 U/L.
The lab report will tell you whether your ALT numbers fall within a normal range, typically about 7 to 56 units per liter (U/L) of blood. Some labs may use other ranges.
Normal levels of ALT (SGPT) ranges from about 7-56 units/liter of serum (the liquid part of the blood), Normal levels of AST (SGOT) is about 5-40 units/liter of serum. Elevated levels of AST and ALT may signify the level of liver damage in a person.
Each laboratory must establish its own normal ranges for ALT (alanine aminotransferase) in the blood. These ranges depend on the makeup of the local population, the technologies used and the accuracy of the measurement.
Male sex, body mass index, glucose, lipids, ferritin, hypertension, and younger age were independent ALT predictors (P < 0.001). Updated URLs were identified at 42/30 U/L in males/females, approximately 30% lower than those currently recommended by the IFCC.
According to the American College of Gastroenterology, the normal value for ALT in blood for people without risk factors for liver disease ranges from 29 to 33 international units per...
The normal range is around 7-35 U/L in women and 7-40 U/L in men. There may be some lab-to-lab variability in ranges due to differences in equipment, techniques, and chemicals used. ALT levels typically do not change much during pregnancy.
