In a prospective observational study, 34 newly diagnosed CD patients, 34 age-sex matched controls with irritable bowel syndrome (IBS) and 16 treated CD patients were assessed regarding the differences in mean lymphocyte count (LY), red blood cell distribution width (RDW) and their ratio (RDW/LY). <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/7607_rrlm_45.jpg"></inline-graphic> Results. Elevated RDW (>14) and lymphopenia (&lt;1.5 x 10e9/L) were more frequently seen in newly diagnosed CD patients compared to IBS control group and treated CD patients. Newly diagnosed CD patients had significantly higher mean values of RDW/LY - 10.09, compared to 7.72 in the CD-treated group and 6.79 in IBS controls (p&lt;0.01).

RDW/LY ratio is a widely available tool which could be used routinely in clinical practice for CD screening.</p></abstract>
