Sometimes it is clear from symptoms and initial blood tests that someone has rheumatoid arthritis, but not always. A diagnosis tends to be made by a consultant rheumatologist on the basis of tests, examination and ruling out other possible causes for symptoms. 2010 rheumatoid arthritis classification.Diagnosis of RA is not straight forward as there is no individual test for RA.

Rheumatoid factors in patients with rheumatoid arthritis. Laboratory evaluation in rheumatic diseases. MRIs are highly sensitive and some studies have found that they are able to detect early joint damage almost three years before conventional X-ray imaging.Īmerican College of Rheumatology. While not commonly performed for diagnostic purposes, MRIs are useful in assessing soft tissue structure, cartilage, and bones. Magnetic resonance imaging (MRI): MRI can also be used in assessing RA.Ultrasounds can also detect early signs of joint erosion, something dated X-rays cannot. Ultrasound imaging can also show the amount of inflammation affecting a particular joint. Ultrasound imaging of affected joints can distinguish the difference between soft tissue swelling and actual inflammation. Ultrasonography: Ultrasonography is a noninvasive imaging option using high-frequency sound waves (ultrasound) to provide useful information regarding the extent of inflammation present.While X-rays are still useful, advancements in technology have led to more sensitive imaging types. X-rays are able to identify late-stage erosions (occurring within three months of diagnosis), structural abnormalities, and joint deformities. X-ray imaging: X-ray imaging has long been the gold standard for evaluating joints affected by RA.
