When reading lab results for Rheumatoid factor -5.0?
A rheumatoid factor over 23 units and a titer over 1:80 indicates rheumatoid arthritis, However this may also occur in other conditions.False positive results can occur when the blood is high in fats.A negative test result for rheumatoid factor does not exclude the diagnosis of rheumatoid arthritis.
Is rheumatoid factor a sensitive test?
Just for some context, patients with suspected rheumatoid arthritis or other rheumatological disease are commonly screened with a rheumatoid factor (RF) test within a hospital. To answer your question, a very recent meta-analysis of the RF test (see related link) found that it was about 69% sensitive and 85% specific.The RF test is sensitive however it is nonspecific. Rheumatoid factor is usually associated with rheumatoid arthritis (RA) but may also be involved in a number of autoimmune diseases, including Sjögrens syndrome,i some and viral infections, and is also found in a small percentage of healthy people.
If your Rheumatoid factor is lower than the previous blood test what does this mean?
This is not known as the cause of it is unknown as well as the relationship between RF and the activity of the disease.
Can you have a positive rheumatoid arthritis test and not be symptomatic?
Yes There is no specific test that will indicate that you have Rheumatoid arthritis (RA). When there is a suspicion that you may suffer from this disease one of the tests done is a test for Rheumatoid factor(RF). About 90% of people that have RA also have an elevated RF. However having a positive or elevated RF does not necessarily mean you are at present suffering from RA.
What are synonyms of seropositive arthritis?
Seropositive Rheumatoid arthritis is RA in a person that has rheumatoid factor in the blood. As opposed to seronegative RA where there is no RF.Rheumatoid arthritis is an autoimmune disease that exhibits itself in a certain way when it is suspected that one has RA ones blood is tested for Rheumatoid factor (a particular antibody) if it is found to be elevated then one is said to have seropositive RA.
What is the purpose of the rheumatoid arthritis factor test?
The rheumatoid factor test is a commonly ordered laboratory test to help rheumatologists diagnose rheumatoid arthritis (RA). To conduct the test, a blood sample is collected from a vein using a needle. The sample is then sent to the laboratory for analysis. The lab will examine the blood to measure the rheumatoid factor, which is a protein produced by the immune system that can attack healthy tissues in a person’s body. High levels of rheumatoid factor can often be a good indicator of an RA diagnosis. In fact, seventy to ninety percent of people who are diagnosed with RA have a positive rheumatoid factor test. If a diagnosis of RA is in fact confirmed, the amount of rheumatoid factor in the patient’s blood may also help their doctor choose an appropriate treatment approach. However, although the rheumatoid factor test is a very useful diagnostic tool, it is important to remember that it is not conclusive of an RA diagnosis. Rheumatoid factor can be found in the blood samples of people without rheumatoid arthritis or in the samples from people who have different autoimmune conditions. It is also possible for someone who does have RA to have no rheumatoid factor present, particularly in the early stages of arthritis, although these cases of RA are generally less severe. Unfortunately there is no single test that can be used to confirm a diagnosis of RA. Instead, rheumatologists must rely on a combination of medical history, clinical exams, and various test results, including the rheumatoid factor test, to confirm a diagnosis of RA.

What does a rheumatoid factor of 415 mean?
A rheumatoid factor test measures the amount of rheumatoid factor in your blood. Rheumatoid factors are proteins produced by your immune system that can attack healthy tissue in your body.High levels of rheumatoid factor in the blood are most often associated with autoimmune diseases, such as rheumatoid arthritis and Sjogren's syndrome. But rheumatoid factor may be detected in some healthy people, and people with autoimmune diseases sometimes have normal levels of rheumatoid factor.Results are usually reported in one of two ways:Less than 40-60 u/mLLess than 1:80 (1 to 80) titerA low number (normal result) usually means you do not have rheumatoid arthritis or Sjogren syndrome. However, some people who do have these conditions still have a "normal" or low rheumatoid factor (RF).Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What Abnormal Results MeanAn abnormal result means the test is positive, which means higher levels of rheumatoid factor have been detected in your blood. Most patients with rheumatoid arthritis or Sjogren syndrome have positive RF tests.The higher the level, the more likely one of these conditions is present. There are also other tests for these disorders that help make the diagnosis.Not everyone with higher levels of rheumatoid factor has rheumatoid arthritis or Sjogren syndrome.Your provider may do another blood test (anti-CCP antibody) to help diagnose rheumatoid arthritis.People with the following diseases may also have higher levels of rheumatoid factor:SclerodermaSystemic lupus erythematosusAdult Still's diseaseDermatomyositisSarcoidosisHigher-than-normal levels of RF may be seen in people with other medical problems. However, these higher RF levels cannot be used to diagnose these other conditions:
