- 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: 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).
