Although phlebotomy is generally safe, some complications can occur: - Hematoma: A collection of blood outside the blood vessels, often causing swelling and bruising. - Infection: Risk of infection at the puncture site if proper aseptic technique is not followed. - Syncope: Some patients may experience fainting or dizziness during or after the procedure. - Phlebitis: Inflammation of the vein, which can cause pain and tenderness.
