Hi there!

While RF values above 20 IU/ml, >1:40 concentration, or over the 95th percentile are strongly indicative of a positive test, neither high levels without symptoms/ radiological evidence indicate RA nor low levels with symptoms/ radiological features refute an RA diagnosis.
Hope this information is helpful.

Tale care!
