Hello, I had the fecal calprotectin test done this summer.  The result was 107.  I know that it said the limit was 50 and above 50 was more than IBS.
Well, I was happy to think finally something shows, here is proof.  When my GI discussed the results with me, he dismissed the 107 as being anything important.  He said he thought that anything can make it show inflammation. 
Well, hello, this really bothers me.  Why have me take this test if you don't rely on what it says.  Now I know, for IBD you would be looking at large numbers, much much higher.  However, should my 107 value be dismissed?
Has anyone had experience with this?
He told me to get a second opinion for everything overall, but I am dragging my feet.  However, yesterday I went to the grocery store and thought we were going to have clean up on aisle 5.
Sigh any thoughts?

Hi Katy,
Welcome to the IBS board!
You are the 1st person since I have been here to bring up the Calprotectin test.  I haven't taken it, but from my understanding it is not used to detect IBS, only IBD.
Sorry I can't help... I just wanted to welcome you.  :-)
Take care.

Hi Katy,
I did look it up and found this link and it shows the ranges of results and the diagnosis of the ranges... it looks like you definitely fall under the inflammation range... did you ask the doctor if you are not in a flare if it tips the scales?

Hugs, Des

Katydid, you should ask CrohnieToo on the Crohn's board about this.  She monitors her inflammation using the fecal calprotectin tests and is a wealth of information!

Thanks for the replies and the welcome.
He didn't explain the results at all, just brushed it aside.
I have spoken with ChronieToo but her levels are many times mine.
My family is pushing me to see a new doc, and I'll talk it over with her when I go.

My 17-year-old son has been suffering with IBS since 2001 due to a reaction to an antibiotic.  Over the last 1.5 years his symptoms have changed and worsened.  We found a new GI specialist who requested the calprotectin test.  His results were 173 ug/g.  Yes, the range for negative is less than or equal to 50 ug/g.  However, borderline is 50-100 ug/g.  Even with a rate of 173 ug/g, our son is considered a low positive.  His GI specialist has requested a second test to confirm it is not a false positive.  Keep in mind the test is checking for white blood cells and the elevation can occur any where in the GI tract from the sinus mucus to the anus.  So, do you self a favor and have a second test.  The test not only checks for IBD it is a potential check for cancer.  Don't play around and good luck.
