What are the risks in an alanine aminotransferase test?

ANSWER

The alanine aminotransferase test (ALT) is a blood test that checks for liver damage. It takes only a few minutes to get your blood drawn. Blood tests are common and safe. Sometimes the needle stick can lead to:

  • Bleeding
  • Bruising
  • Infection
  • Slight pain when the needle is inserted
  • Fainting or feeling dizzy
