Rheumatoid arthritis factor ra latex turbid-RA Latex Turbid Test: Normal Range

RA is a chronic disease that leads to inflammation of your joints. In some cases, the inflammation may be so severe that it affects how your joints function. It can also cause joint deformities. RA is an autoimmune disease. An autoimmune disease is when your immune system attacks a healthy part of your body by mistake.

A positive for rheumatoid factor test results means that it can lead to latez is the cause of inflammatory symptoms from an autoimmune disorder. High levels of rheumatoid factor in the blood are most often associated with autoimmune diseases, such as rheumatoid arthritis and Sjogren's syndrome. RF may be elevated at low levels in other autoimmune Rheumatoid arthritis factor ra latex turbid. Joint pain, swelling, and stiffness aren't the only symptoms of RA.

It sounds like you are doing everything you can to advocate for your health. An increase in the turbidity of the sample indicates the presence of RF. In some cases, the inflammation may be so severe that it affects how your joints function. Rheumatoid arthritis factor ra latex turbid Lauren Tucker September 6, at am Keymaster We are glad that you have found our site too karmacola and sorry to hear you have been feeling unwell for some time. However, tests that help identify RF levels may not provide enough information to make a diagnosis, so a doctor will usually recommend additional tests. The RA latex turbid test uses an RF-specific antibody that is affixed to a latex bead to check for the presence of RF in a serum blood sample. In Spiritual highly sensitive to help confirm a diagnosis of RA following a high RA turbid latex test result, your doctor may order additional tests. Physicians typically run this test on individuals who are already presenting with symptoms of RA. The RA turbid blood test is just a specific test to measure the rheumatoid factor. Most people who undergo an RA latex turbid test can also expect to have an anti-cyclic citrullinated antibody anti-CCP test, which is a blood test that checks for the levels of anti-CCP. Your entire medical history and pattern of symptoms will be combined with the results of this blood test to come to a diagnosis.

A rheumatoid factor test measures the amount of rheumatoid factor in your blood.

  • By karmacola August 31, at am.
  • RA is a chronic disease that leads to inflammation of your joints.
  • Rheumatoid arthritis RA is a chronic autoimmune disease that primarily affects the joints, but can affect other parts of the body.
  • Have you just been told that you have rheumatoid arthritis because of your RA turbid blood test results?
  • Results outside of the normal range may be a sign of an underlying condition, but the rheumatoid arthritis RA latex turbid test is just one part of a thorough diagnosis.
  • An RA latex turbid test determines whether or not a patient is suffering from rheumatoid arthritis, an autoimmune disorder that affects the joints.

Rheumatoid arthritis RA classically presents as a symmetrical arthritis, although a single large joint synovitis may be the initial presenting symptom. Patients of any age or sex may be affected; however, the disease most often occurs in young, middle-aged women. A patient with swelling of at least 1 large or multiple small joints that cannot be associated with another defined clinical condition should be tested for RA.

The most commonly affected joints are the metacarpophalangeal and the proximal interphalangeal joints; however, other joints, both large and small, may be affected. Morning stiffness lasting more than minutes is highly indicative of RA or other inflammatory arthritic conditions. The more joints that are affected and symptoms lasting more than 6 weeks increase the likelihood of RA.

The Rheumatoid Arthritis Classification Criteria include two laboratory test categories. The first category is serology, which includes a rheumatoid factor assay RF and an anti-cyclic citrullinated peptide assay anti CCP. Table 1.

The laboratory should report quantitative values for each of these assays. At least one test result from each category is necessary for a definitive diagnosis. Additional blood tests that may be ordered in a patient presenting with RA-type symptoms include a complete metabolic panel, complete blood count CBC , complement studies, and an anti-nuclear antibody, which can help to differentiate RA from other autoimmune diseases, such as systemic lupus erythematosus or mixed connective tissue disease.

Immunosuppressive medications may reduce the sensitivity of the serologic and acute phase reactant assays. RF may be elevated at low levels in other autoimmune diseases. Both CRP and ESR are non-specific indicators of inflammation and may be elevated in infections or injury, as well as in other rheumatic or autoimmune diseases. Hepatitis C is often associated with a cryoglobulin that may have rheumatoid factor activity. No laboratory test is absolutely confirmatory for RA.

However, the guidelines direct that either a CRP or an ESR test must be performed, even in the presence of multiple joint synovitis and a positive serologic assay. Anemia, thrombocytosis, leukocytosis, and low albumin levels may be present in RA patients but are non-specific findings. In addition to a standard RF assay, a cryoglobulin test may be useful. Types 2 and 3 cryoglobulins have rheumatoid factor activity. Positive results may be associated with RA or possibly Hepatitis C infection.

A synovial fluid examination may be ordered if the serum tests are all negative. The fluid from an RA patient will likely show a leukocytosis and may have low C3 and C4 complement levels.

Normal synovial fluid complement component concentrations are approximately one-third of that found in serum. Synovial fluid analyses are not included in the specific RA classification scheme, however. More recently, biomarkers, such as Interleukin 18, have been shown to be elevated in RA.

However, no clinical assays are currently available for these proteins. There are no documented drug interferences in these assays. RF and CRP results obtained by nephelometry may be falsely elevated in lipemic sera or sera containing other particulates. All rights reserved.

Testing for these antibodies is often an important part of diagnosing whether a person has RA. If a person's test results come back within normal RF ranges, but their symptoms persist, doctors may use other tests to help identify the underlying cause.

In order to conduct this test, your doctor will need to collect a blood sample from a vein in your arm. The sample is then typically sent out to a laboratory where the test is performed.

Values higher than this could be an indication of the presence of RA or other autoimmune disorders, post-viral syndromes, and underlying cancers. The higher your result value is, the stronger the likelihood that you have RA. However, some people may have a high value without having RA, and some people with RA may not have a high value.

If you have only a slightly higher-than-normal RA latex turbid value, your doctor will very likely order additional tests to confirm a diagnosis. However, you can still have a higher-than-normal test result and not have RA. There are a number of other diseases or conditions that can cause a high result value.

These include:. Additionally, a higher-than-normal test result can also be found in older adults and in a low percentage of healthy people. In order to help confirm a diagnosis of RA following a high RA turbid latex test result, your doctor may order additional tests. The tests may include:. Some general symptoms of RA include:. These symptoms can include:. Your doctor will work with you to discuss your symptoms and will order tests to aid in a diagnosis. Because RA has a strong genetic component, tell your doctor if you have family members with RA or other autoimmune diseases.

Learn about life expectancy, complications, and more. Diagnosing rheumatoid arthritis RA involves a few steps including reviewing symptoms, blood tests, and imaging tests. Negative levels do not exclude the disease, and positive levels do not guarantee the diagnosis. Some conditions and medical procedures that can raise RF levels include: other autoimmune diseases, certain chronic infections, diabetes, bacterial endocarditis, cancer, normal aging, vaccinations and transfusions.

Another test which is ordered when rheumatoid arthritis is suspected is the anticyclic citrullinated peptide anti-CCP. A level above 20 suggests the possibility of RA. Once a patient develops a positive anti-CCP, it will usually remain positive, despite remission. In these cases, the physician makes the diagnosis based on physical examination and imaging. RF and anti-CCP are not used to monitor disease activity, because they both tend to remain positive despite remission.

Once the diagnosis of RA has been made and confirmed, these tests are not repeated. Sedimentation rate also known as erythrocyte sedimentation rate or ESR , is a crude measure of inflammation. It is calculated by measuring the rate at which red blood cells sediment in a test tube in one hour. The ESR rate is not specific for RA, and there are many factors that can interfere with the results, such as bad processing, an infection, and aging in patients over the age of C-reactive protein is another measure of clinical inflammation.

The normal measurement is less than 1. This test, however, can be influenced by factors such as obesity and infection and is not specific to RA. A complete blood count CBC test looks at red and white blood cell counts.

RA is a chronic disease that leads to inflammation of your joints. In some cases, the inflammation may be so severe that it affects how your joints function. It can also cause joint deformities. RA is an autoimmune disease. An autoimmune disease is when your immune system attacks a healthy part of your body by mistake. People with RA produce a specific type of antibody, known as rheumatoid factor RF.

It can be found in the blood or joint fluid of most people with RA. The RA latex turbid test uses an RF-specific antibody that is affixed to a latex bead to check for the presence of RF in a serum blood sample.

This binding causes a decrease in the light intensity that can be transmitted through the particles in the sample turbidity. An increase in the turbidity of the sample indicates the presence of RF. These symptoms include joint pain or swelling, or unexplained symptoms like rashes, muscle pain, and fevers.

In addition to the RA latex turbid test, your doctor may also order additional tests that can help check for autoimmune conditions. Examples of some of these tests include:. In order to conduct this test, your doctor will need to collect a blood sample from a vein in your arm.
