Lab test question on RF test.

[Tammy4330]

The Rheumatoid Factor on my RF, Serum, Quant test was <15. What does this mean?

Thank's for your reply. Unfortunately, I was diagnosed with RA a few years ago. I see a Rheumatoligist quite often.I have been told that ANA factors can show at some times and not at others. This test however, is different than any of the tests I have seen before.

its normal range for RF saline is less than 20..If Its more than 20 than more tests r done to come to the final diagnosis.. RF is in various dis. like rheumatoid  arthritis,SLE,connective tissue disorders etc

so there's nothing to worry u r safe from all these

enjoy!
