I'm 27 yrs. Old. Blood results today: ALT: 56 and Vitamin B12: 993. Don't drink. Last years blood exam was fine. What could this mean? Thank you

Any medications? All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your B12 level is okay. ALT is slightly elevated. If you are taking any medications, that may explain the rise. Please discuss the need to be tested for hepatitis, with your doctor.
