Carcinoid Syndrome

Healthcare providers may use the following tests to diagnose carcinoid syndrome:

• Urine test: This test checks on certain hormone levels.
• Physical exam and medical history: Many carcinoid syndrome symptoms are similar to other less serious illnesses. Your healthcare provider will ask questions about specific symptoms, how long you’ve had the symptoms and if your symptoms are getting worse.
• Blood tests: These tests check on the amounts of substances that your organs and tissues release into your blood. Substance levels that spike or fall might be signs of disease.
• Neuroendocrine positron emission tomography (PET) scan: This test tracks neuroendocrine tumors with a dye called Gallium 68 dotatate.
• Computed tomography (CT) scan: CT scans use X-rays and a computer to produce 3D images of organs and bones.
• Ultrasound: Ultrasounds use sound waves to develop images of organs and bones.
• Magnetic resonance imaging (MRI): This uses a computer, radio waves and a large magnet to create images of the inside of your body.
• Endoscopy: For this test, a provider inserts a long thin tube with a camera and a light into your body.
