When three negative are multiplied is the product positive or negative?
It is a positive. When you multiply a negative and a negative, it becomes a positive, then you multipy the positive with the other positive
What multiplies to equal 22?
To answer this question,we have to find the factor of 22.Factors of 22 are 2 & 11,so 11 multiplies 2 equals to 22.
What is the largest factor of 120?
The largest factor of 120 other than 120 is 60 because 60x2=120 The largest factor of 120 other than 120 is 60 because 60x2=120 The largest factor of 120 other than 120 is 60 because 60x2=120 The largest factor of 120 other than 120 is 60 because 60x2=120
What is a negative scale factor?
A negative scale factor is used to produce the image on the other side of the centre of enlargement (scaled to the absolute value of the scale factor).
What is a negative decimal divided by a positive decimal?
You just divide like you would divide any other decimal, and then... Positive and Positive = Positive Negative and Negative = Positive Positive and Negative = Negative I hope my answer helped! :)
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.
Other associated names for rheumatoid factor?
It seems that rheumatoid factor is the only name that is used for it.
What is a negative rheumatoid factor?
rheumatoid factor is a particular type of antibody that is found in about 80% of people have Rheumatoid arthritis as well as with other inflammatory illnesses. A negative RF simply means there is no RF in the blood.
What is the significance of elevated rheumatoid factor and positive ANA?
10 million Americans have a positive ANA or antinuclear antibody test 1.5 million have a form of lupus. Of all those lupus patients, about 5% will have a negative ANA. The ANA titer is not directly linked to the level of disease activity in lupus. The ANA is just one of a variety of tests used in the difficult process of diagnosing this disease. In addition to a positive, the pattern seen under immunofluorescence is significant. A positive ANA coupled with a speckled pattern is more indicative of lupus than a homogeneous pattern. Lupus is diagnosed based on medical history, symptoms, a wide variety of laboratory tests of which the ANA is just one, and after ruling out other disease that lupus often imitates.
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:
What is RA factor?
Rheumatoid factor (RF or RhF) antibody directed against an organism's own tissues) most relevant in rheumatoid-arthritis. It is an antibody against the Fc portion of immunoglobulin-g-1, which is itself an antibody. RF and IgG join to form immune-complex-1 which contribute to the disease process. About 80% of people with rheumatoid arthritis have detectable rheumatoid factor. Those who do not are said to be "seronegative".Rheumatoid factor can also be a cryoglobulinemia-1 (antibody that precipitates on cooling of a blood sample); it can be either type 2 (monoclonal IgM to polyclonal IgG) or 3 (polyclonal IgM to polyclonal IgG)RF is often evaluated in patients suspected of having any form of arthritis even though positive results can be due to other causes, and negative results do not rule out disease. But, in combination with signs and symptom, it can play a role in both diagnosis and disease prognosis. It is part of the usual disease criteria of rheumatoid arthritis.The presence of rheumatoid factor in serum can also indicate the occurrence of suspected autoimmune activity unrelated to rheumatoid arthritis, such as that associated with tissue or organ rejection. In such instances, RF may serve as one of serology markers for autoimmunity. (source wikipedia)
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.
How long between the time when you notice rheumatoid arthritis until the test comes back positive?
There is no definitive l test for RA. the test that are done are a collection of different things that take place in the body. such as rheumatoid factor, inflammation rates, cartilage damage, presence of rheumatoid nodules and other things. However a doctor such as a rheumatologist can be reasonably certain what he is dealing with within a few days of blood tests and xrays being done.
What is an Rf factor and how is it calculated?
The Rf value is the "ratio to the front." Hence the R and the f. It is defined as the ration of the distance traveled by a spot (measured from the center) to the distance traveled by the solvent.
What is a normal 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) generally means you do not have rheumatoid arthritis or Sjogren syndrome. However, these conditions still can still occur in some people who have have a "normal" or low rheumatoid factor (RF).Normal value ranges may vary slightly among different laboratories.Rheumatoid factor (RF) blood tests measures the amount of the RF antibody in the blood.The results of the rheumatoid factor (RF) test may be reported in titers or units:A titer is a measure of how much the blood sample can be diluted before RF can no longer be detected. A titer of 1 to 20 (1:20) means that RF can be detected when 1 part of the blood sample is diluted by up to 20 parts of a salt solution (saline). A larger second number means there is more RF in the blood. Therefore, a titer of 1 to 80 shows more RF in the blood than a titer of 1 to 20.Nephelometry units indicate how much light is blocked by the blood sample in the tube. A high level of RF causes the sample to be cloudy, so less light passes through the tube than when the RF level is low. So an RF level of 100 units is higher than one of 40 units.NormalNormal values vary from lab to lab. Results are usually available in a day or two.Rheumatoid factor (RF) Titers1:20 to 1:80 Units14 units/mL to 60 units/mLPatients should check with their heath profesional to see what the normal range is for the lab that tested your blood.Rheumatoid factor is an immunoglobulin (antibody) which is able to bind to other antibodies. Rheumatoid factor is usually not found in the general population. it is only found in about 1-2% of healthy people. Rheumatoid factor increases with age and about 20% of people over 65 years old have an elevated rheumatoid factor.A blood test is done to detect the presence of rheumatoid factor. This is normally ordered to diagnose rheumatoid arthritis. Rheumatoid factor is present in 80% of adults who have rheumatoid arthritis The incidence of rheumatoid factor increases with duration time: at 3 months the incidence is 33%, at one year it is 75%. Up to 20% of rheumatoid arthritis sufferers remain negative for rheumatoid factor (also known as "seronegative rheumatoid arthritis") throughout their disease.Results are usually reported in one of two ways:Normal values are LESS than 60 U/ml.A 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).
What is Rheumatoid factor?
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 usually means you don't 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.
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.
