Hi all I saw my consultant 3 months ago and he said my das was 6.9 I went to him again last friday and he said my das has gone up and is 9.8 but I dont wunderstand whathe means and I keep for getting to ask him, I have RA for the last 2 year but 3 months ago was told I have lupus and fibro as well

I am waitinv to start infusion of ruxi but the consultant told me not to hold my breath as he doesnt think it will work as you need to have some immune system for to grab onto I asked why he was giving it to me he stated that the government say that is the next courxe of action to use, it seems that they have there hands tied sometimes in what they can try at what stage, I have never been stable since being doignosed, can anyone help explain this das score thanks micky

  • Hi micky40,

    DAS stands for Disease Activity Score and it is a way of measuring how active your disease is. The lower the score, the less active the disease is and the aim is to get you to remission which is a score of 2.6 or less. I have put a link to the section on our website that explains about DAS and how it is measured:


    Hope this helps

  • DAS means disease activity score, so just a complicated way of describing how active your disease is. Over 9 is high! The aim is to be under about 2.5 which is generally thought to be in remission... It's calculated by counting how many tender and swollen joints you have, using your most recent Blood test results and asking you how you are on a scale of 1 to 10. This all goes into a formulae and out comes the result. Here's a link to a site where you can try it yourself....


  • Thankyou so much

  • Thankyou so much

  • Please don't be afraid, in future, to ask your consultant about things you don't understand. That is what he/she is there for.

  • Have a look at the information on NRAS site - lots there on DAS and other ways of managing your condition. The more you know the better you can manage.
