Nothing here is personalized to you, and using this site does not create a doctor–patient relationship.
Reference ranges differ between laboratories and by age, sex, and method — always use the range printed on your own lab report.
If you have symptoms or concerns, consult a qualified healthcare professional. If you think you may have a medical emergency, contact your doctor or local emergency services immediately.
ALT is a liver-related blood test. A higher result may be associated with liver irritation, recent illness, medicines, exercise, or other factors. Educational only, not a diagnosis.

No. A higher ALT may be associated with several causes, and clinicians usually interpret it with other blood tests, symptoms, and your medical history.
Yes. Intense exercise can sometimes affect liver-related enzymes, which is one reason clinicians look at the broader pattern before drawing conclusions.
ALT is commonly reviewed with AST, bilirubin, and alkaline phosphatase because one number alone gives limited context.
