The Normal ALT Levels By Age Chart provides reference ranges for Alanine Aminotransferase (ALT) levels in different age groups. ALT is an enzyme found predominantly in the liver, and elevated levels may indicate liver damage or disease. The chart outlines the normal range of ALT levels (measured in units per liter - U/L) for individuals within specific age brackets, from 0-9 years old to 80 and above.
Chart Data
| Age | Normal ALT Levels (U/L) |
|---|---|
| 0-9 | 7-56 |
| 10-19 | 9-59 |
| 20-29 | 9-59 |
| 30-39 | 9-59 |
| 40-49 | 9-59 |
| 50-59 | 9-59 |
| 60-69 | 9-59 |
| 70-79 | 9-59 |
| 80+ | 9-59 |
Conclusion
The Normal ALT Levels (U/L) for different age groups generally fall within the range of 9-59 units per liter, with consistent values from age 10 to 80 and above. This suggests a consistent reference range for ALT levels across various age groups.
FAQ
What are normal ALT levels in adults?
Normal ALT levels for adults are typically between 7 to 56 units per liter (U/L).
What are normal ALT levels in children?
Normal ALT levels in children can range from 10 to 60 U/L, depending on the age of the child.
Do ALT levels change with age?
Yes, ALT levels can vary with age. They are generally higher in infants and children compared to adults.
At what age do ALT levels peak?
ALT levels tend to peak in infancy and then gradually decrease with age, reaching adult levels by the teenage years.
What factors can affect ALT levels besides age?
Factors such as certain medications, liver diseases, alcohol consumption, and obesity can also impact ALT levels.
