A rheumatoid factor (RF) blood test measures the amount of the RF antibody present in the blood.
The results of the rheumatoid factor (RF) test may be reported in titers or units:
The normal values listed here-called a reference range-are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.
You can usually get the results within 24 hours.Rheumatoid factor (RF)Titers
Less than 1:80Units
Less than 60 units per milliliter (U/mL)
Check with your doctor to see what the normal range is for the lab that tested your blood.
High valuesHigh RF levels may be caused by:
Rheumatoid factor (RF or RhF) is an antibody that attacs an organism's own tissue. omos often found in 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 (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)
At this stage the reason for rheumatoid factor is still unknown.
This is not known as the cause of it is unknown as well as the relationship between RF and the activity of the disease.
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.
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.

Yes, as a matter of fact you can have RA with no rheumatoid factor at all.
At this stage the reason for rheumatoid factor is still unknown.
7 is a prime factor of 189, because 7 X 27 = 189.
It seems that rheumatoid factor is the only name that is used for it.
it is the factors of 189
This is not known as the cause of it is unknown as well as the relationship between RF and the activity of the disease.
The greatest common factor of 81 and 189 is 27.
The Greatest Common Factor of 189 and 449 is 1.
Since 27 is a factor of 189, it is automatically the GCF.
189 63,3 21,3,3 7,3,3,3
They are: 333*7 = 189
