Inflammatory bowel disease (IBD) is characterized by destructive inflammation of the intestinal tract with ulcerative colitis and Crohn’s disease as the most common disorders. Both diseases are life-long conditions with periods of remission and relapse.1

  • About 10 percent of IBD patients are misdiagnosed with irritable bowel syndrome (IBS) and in 3 percent of cases, this may persist for five or more years.2
  • The time to diagnose Crohn's disease from onset of symptoms takes, on average, nine months.3
  • An early diagnosis in IBD matters, as it is associated with improved patient outcomes and increased treatment success.3-6
  • Because of its 98 to 99 percent sensitivity for IBD, a negative EliA™ Calprotectin 2 test result helps to rule out IBD and thus differentiate between inflammatory and non-inflammatory bowel diseases, potentially avoid endoscopy, and reduce the associated patient risk.7,8

 

Why choose Thermo Fisher Scientific as your partner in IBD diagnostics?

 

Reducing avoidable invasive procedures.

The EliA™ IBD portfolio, comprising the EliA Calprotectin 2 and the EliA™ ASCA IgA and IgG tests (ASCA: anti-Saccharomyces cerevisiae antibodies), supports the identification and the differentiation of IBD.

The follow-up of a positive EliA Calprotectin 2 test result with EliA ASCA IgA and IgG tests and a p-ANCA indirect immunofluorescence assay (IFA) helps differentiate between Crohn’s disease and ulcerative colitis, potentially avoiding further investigations and providing guidance for endoscopic procedures.9,10

 

Results you can rely on.

The high sensitivity (98-99%) of the EliA Calprotectin 2 test, together with a negative predictive value (NPV) of 98.4 percent, make the test an outstanding tool helping to rule out inflammatory bowel disease.7,8

 

A test portfolio optimized to help differentiate between gastrointestinal diseases.

The EliA™ gastrointestinal portfolio* enables you to help rule in or rule out IBD (and subsequently differentiate between Crohn’s disease and ulcerative colitis), IBS, celiac disease, non-celiac gluten sensitivity, and wheat allergy.

The EliA gastrointestinal portfolio can be measured from one sample in one run and on the same fully automated Phadia™ Laboratory Systems.
