This information was so helpful. In 2014, my anti ccp test was positive with a fairly high number. I also had extensive joint damage in my large joints. I was treated for RA for several years. Five of my large joints were replace before I turned 50.
In 2020, after a bout of fairly alarming scalp psoriasis with hair loss, new labs revealed a positive Hbla-27 response. I have slight nail pitting and a very painful foot and ankle.
My rheumatologist now has me in the PsA category.
My disease is fairly active at the moment. Lots of pain, a sausage finger, fatigue, Uveitis - really not a fun month. I had routine labs done today and the inflammation markers are normal. I felt puzzled that my labs did not tell the story of how I feel.
This article helped settle my mind. And I am fortunate to have an outstanding rheumatologist. He reminds me that labs do not tell the whole story.
