Hi Karen,

I googled this because i was curious myself.  It appears that 1-20 just shows that there is an RF present in the blood.  Numbers higher than that are probably showing a more severe level of RA.  The really scarry thing is I have seen other on this site with large, large numbers like 700!

Wish you luck with this and hope it helps!

Hi Karen...it's hard for me to decipher the RF #s as (I think) it depends on the lab or the measurement used or something! If you have the lab paperwork, you could look there. Mine just said something about <14 = negative, >15= positive, >20 = strongly positive.

But 290 sounds high to me!

My understanding is that there really is no single test for RA, so "tested negative for RA" makes me wonder which test was negative? There are like 9 or 10 specialized blood tests for RA. Each is a piece of the puzzle when being diagnosed.

Hi Jamie,

 

I also have a 5 yr old, if enbrel isn't working for you anymore talk to your dr about Humira.  It's a shot like enbrel, but only 2 x a month, instead of every 3 days.  More severe cases like me, take it once a wk...

 

Good Luck,

Jayme

Hi Karen,

 

I have had JRA since I was a child, I currently have a Rheumatiod factor of over 600,  I am currently in a flare up.  Your RF ultimtly should e below 100, however, my Rheumy says that the RF # means nothing.  He tells me the number you need to watch is your SED Rate.  It should be below 20, mine currently is 63, bit like I said, I'm having a flare up.  The best meds I have had is Humira, that brought me out of my last flare up, after I had my son.  So now since Humira isn't working anymore my Rheumy wants me to try Simponi.... A brand new shot (it used to be only offered by infusion), so lets hope it works, and good luck to you!

Hi Karen,

 

I have been monitoring my rheumatoid factor for about 16 years due to possible auto immune disorders that could be caused from silicone breast implants.  I have seen my level go from 44 to 777.  It seems to fluctuate but now is always over 200. But I don't have symptoms. I have seen several doctors who specialize in this area and I'm told that apporx 1-2% of the general population has elevated factors for no known reason.  Why were you tested in the first place?  If you don't have any symptoms I wouldn't be concerned.  J

Hi Karen, From my own experience, you really need to take care of that, in my case i went to my doctor last 2 weeks as I had some stifness in my left arm, and pain in my right jaw and my neck, I did the lab work,everything seems fine exept for RF it was 199, my doctor told me that I had to see Rheumatologist because it is something that has to do with the blood cells fighting some glands inthe body, So I am going next week to see rheumatologist......

I just got my blood work back and I was surprised to see my rheumatoid factor was 2330!  Sed rate was at 87 (I have been this high before).  I have primary sjs but never had an RA factor that high.  What could cause this?
