A result of 19 IU/mL on a rheumatoid factor (RF) test is considered within the normal range for most labs, as normal values are typically less than 20 IU/mL.

A result of 19 IU/mL on a rheumatoid factor (RF) test is considered within the normal range for most labs, as normal values are typically less than 20 IU/mL. This would generally be interpreted as a negative result, meaning it does not strongly suggest rheumatoid arthritis. However, RF levels alone cannot confirm or rule out RA, as some people with RA have normal RF levels. Always discuss results with your doctor for proper interpretation.
