Arthritis
Lab Tests and Imaging In addition to reviewing family history and a thorough physical exam (discussed on the previous page), doctors often employ the following high-tech tools to diagnose arthritis: The doctor may order some laboratory tests to help confirm a diagnosis. Samples of blood, urine, or synovial fluid (fluid found in the joint) may be needed for the tests. Common laboratory tests include:
X-Rays and Other Imaging Procedures Doctors may ask for X-ray or other imaging procedures to review the condition of the joint. X-rays provide an image of the bones while other imaging methods like Computed Tomography (CT or CAT) or Magnetic Resonance Imaging (MRI) can be used to show the whole joint. Arthroscopy Doctors use a device called an Arthroscope which is a small, flexible tube that transmits the image of the inside of a joint to a video screen and examine damage to a joint. The Arthroscopy allows the doctors to see inside the joint. Also doctors use arthroscopy to perform surgery for some types of joint injury.
