PROMETHEUS® Celiac PLUS provides more comprehensive, accurate answers
- Only Prometheus genetic testing quantifies the relative risk of disease for every patient
- Clear risk stratification may enable you to prevent disease onset
- A negative predictive value (NPV) of 95% to 100% allows you to rule out celiac disease for life2
Now you can assess your patients' risk |

Most celiac patients carry either the DQ2 haplotype (about 95% of celiacs) or the DQ8 haplotype (about 5% of celiacs). There are two DQ2 haplotypes, but only one DQ8 haplotype—specific combinations may confer different risks for the development of celiac disease, as shown above.
