There are some tests for rheumatoid arthritis that the doctor will have to take so as to diagnose if you are suffering from rheumatoid arthritis. If you present the symptoms that make the doctor suspect you to be suffering from rheumatoid arthritis, he will need to take blood samples from you in order to do the tests. These blood tests will not only confirm that you have rheumatoid arthritis but they will also help the doctor determine which type of arthritis you are suffering from. The tests can be taken to determine the level of inflammation, the severity of the disease, the level of damage and also to diagnose the kind of disease including rheumatoid arthritis; this is because there are many diseases that can cause inflammation in the body.
Rheumatoid arthritis patients will have the results that show they have about 70%- 90% of rheumatoid factor antibodies in the blood. People whose blood tests show no rheumatoid factor present in their blood when rheumatoid tests are taken mean they have no rheumatoid in their body. The rheumatoid factor is also used to diagnose the severity of the disease in the body, if the patient is suffering from rheumatoid arthritis and the test shows no presence of rheumatoid factor, it means that the disease is not severe. Rheumatoid factor shows in about 80% of the adults affected by rheumatoid arthritis while just a small percent will be present in children.
The other test for rheumatoid arthritis that the doctor can take is the anti-CCP test. This test is meant to determine the amount of antibodies present to blind the citrulline modified proteins. This test is more directed to people suffering from rheumatoid arthritis or those suspected that they will develop the disease. The ESR (erythrocyte sedimentation rate) test can be taken to determine the level of inflammation in the rheumatoid arthritis patient. In this test, the red blood cell will tend to fall in the test tube at higher rate when the inflammation is severe. However, this is different from people who are healthy; the sed. rate will be low and does not rise at any time. The C-reactive protein test can also be used to determine the inflammation rate in the body. This test for rheumatoid arthritis will be higher in cases of severe inflammation.
The doctor might also decide to take an x-ray to determine the level of the damage caused by rheumatoid arthritis. The x-ray and screening rheumatoid tests are very significant as they are specific on the level of the disease. In the case of rheumatoid factors tests, they do not have to be positive only in the cases of rheumatoid arthritis presence. People with no rheumatoid arthritis in their body can also have rheumatoid factor present in their body. That is why it is important to take other tests to confirm the presence of rheumatoid arthritis. In the rheumatoid arthritis patients, the rheumatoid factor test will help determine manifestations of other rheumatoid arthritis related disorder like development of nodules and the lung diseases caused by rheumatoid arthritis.
