My serology 7 test came back as negative. My GI explained that fistulizing Crohn's tends to show up more on this blood test as opposed to non fistulizing Crohn's. Interesting as well, my blood work ALWAYS came back as normal, even when they checked for inflammation levels. Luckily, I was able to get my official diagnosis of Crohn's from the pill cam.
Sorry breegs! I haven't checked on this post for awhile.
I am so glad Snohare came along and answered that for you!
If you do have the pill cam, it is pretty cool! To be honest, I was both sad and relieved when I got diagnosed. I had had some pretty miserable symptoms with the Crohn's and not having a definitive answer for them was frustrating. Plus, getting that diagnosis "opened the door" for me to get on Remicade, which has greatly improved my life.
Best of luck to you and keep us posted!
I'm very new here...still in the process of getting diagnosed, but my experience is that the blood test isn't that accurate. After my colonoscopy, upper endoscopy and biopsies indicated Crohn's, a lot of my symptoms subsided for a while, so the doc said we should confirm with the blood work. The blood work came back negative, and he told me that meant I didn't have Crohn's. OF course, I got super excited and relieved! But, going back for follow up tests showed that it probably was. When I asked the doc about the negative blood, he said the test is supposed to be 90% accurate, but in his experience more like 50-60%. Not good enough to tell someone they DON'T have it, in my opinion! I just did the pill camera last week as a final confirmation, so should get those results back then...
Anyway, I'm skeptical of the blood test...
