I was first tested for RA about a year and a hlaf ago. My RA Factor came back at 19. I was tested again 4 months ago and the Factor was 140 with a confirming CCP of 170. I got tested again 2 weeks ago but the lab they used this time gave a ratio for the RA Factor instead of a straight out number (My CCP was 40 this go 'round). Does anyone out there know how to convert the ratio ot an actual number so I can have some idea of keeping track.
Thanks!
Steph
