I have had several Vectra tests as my rhuematologists uses it to help us decide if medications are working. All of my results have been in the 50's so even though my inflammatory markers have come down I am still having active disease activity. I have found this test helpful as when my inflammatory markers came down she thought the meds was working but I was still feeling bad, doing the Vectra helped us decide we needs to move on to a new medication. Look at their website as it has lots of helpful information. Good luck!!
