Re: Rheumatoid Factor/Numbers?/For

Dear :

Hi , it is Colletti, how have you been? I am okay. I just read

this email and I have a question for you. When I had a Rheumatoid Factor

done my Dr. said it was kind of high, over 400. I see in this post it has

measurements as 1:120 or 1:180 and others. Would you know why my Dr. told me

it was over 400 and what that means. I am sure the test was a Rheumatoid

Factor. Could it mean like 1:400 or something like that. I can ask him when

I see him but I wanted to know what you thought about this. Take care and

Happy Birthday.

Thanks for your help.

Sincerely,

Hi, ! Nice to hear from you. I'm glad you are OK. Thanks for the

birthday wishes. I'm OK, too, thank you.

I'm guessing that in your case your RF was reported as 400 IU/ml

(International Units per milliliter), but it's hard to say without more

information. Do you have copies of any of your labs? On the printout

they usually give your result and the range for normal, and then you can

try to see what all of it means. Let me know if you have any copies of

your labs and we can take a stab at it. By all means though, ask your

doctor about this when you see him if you are curious.

This is why I was lamenting in my response to Jeanne that the tests

aren't standardized. There are numerous methods for testing for RF and

many different ways of reporting the result. It's very confusing for

patients and doctors. Apples to oranges comparisons all over the place!
