An important part of maintaining a healthy body is also maintaining a healthy immune system. The immune system is flowing with antibodies that help the body fight infections and disease. However, in some people, a rheumatoid factor (also referred to as RF) is present which alters the way the immune system performs and its effectiveness on disease and infections.
Rheumatoid factors are parasitical antibodies that attach and bind themselves to healthy antibodies. The RF tend to concentrate on destroying the soft tissue in the host body. When the immune system attempts to destroy the RF antibodies, the once healthy antibody that has been bound to it is also destroyed which starts to wreak havoc in the system.
RF can be measured in blood serum and is generally a reliable detector of autoimmune disease as well as some other conditions. Rheumatoid Arthritis (RA) is the most common diagnosis in people exhibiting elevated RF though not the only possibility. High levels of RF can also be associated with conditions such as lupus and liver disease. Several other infectious diseases such as syphilis, tuberculosis and hepatitis can also be diagnosed with the help of a RF level test.
Testing the factor level in people exhibiting symptoms of RA and the various other possible conditions is helpful in making a diagnosis. The tests can often be an early warning system in people who have a family history of RA or other Rheumatic conditions. The tests and subsequent RF level results are not the only factors used when making a diagnosis since the level of RF in the blood is not always a positive indicator.
Only about 80% of people afflicted with RA will show elevated RF levels. This percentage is smaller for patients under the age of Eighteen. For this reason, doctors are careful to not rule out a specific disease based on low or non-existent RF levels. Many people who suffer with an autoimmune disease will have no indication of RF in their blood. Other symptoms will also need to be considered, though high RF levels are strong indicators of the severity of rheumatic diseases.
Sometimes a perfectly healthy person will test positive for RF in their blood. This happens most often in families with a history of RA or other Rheumatic conditions. Though not yet positively determined, it is believed this anomaly occurs because RA may be an inherited disease that lies dormant in many people.
Rheumatoid lung disease and Rheumatoid nodules are two examples of additional rheumatic disease conditions that are not related to joint damage and may occur in people with elevated levels of RF. The nodules are not usually fatal but can be painful. They vary in size and develop just below the skin, usually near damaged joints. The lung disease, however, is a silent threat. It commonly shows no symptoms until damage to the lung has already been done.
Using the rheumatoid factor test to diagnose and determine various rheumatic or infectious conditions within the immune system is very helpful. Even with the occasional misleading results, more often than not, the tests can aid in preventative treatment. The level of RF in the bloodstream is usually a good indicator of how advanced a disease or infection has become.
Rheumatoid factor test is described as a test that is carried out to gauge the rheumatoid factor that is present in the blood. Find out more at: http://Rheumatoid-Arthritis-Symptoms.co
