    Study Notes

    Gastrointestinal Diagnostic Procedures

    • Gastrointestinal (GI) diagnostic procedures use endoscopes and X-rays to view the GI system and assess contents.
    • Procedures include liver function tests, blood tests, urobilinogen tests, fecal occult blood tests (FOBT), stool samples, endoscopy, and GI series.

    Liver Function Tests & Other Blood Tests

    • Liver function tests include: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin, and albumin.
    • Other GI-related blood tests include: amylase, lipase, alpha-fetoprotein, and ammonia.

    Indications

    • Use for suspected liver, pancreatic, or biliary tract disorders.

    Considerations for Patients

    • Pre-procedure: Explain to the client how blood is drawn and what information these tests will provide.
