Intervention type: OTHER
Group type: ACTIVE_COMPARATOR
Intervention: Tumor marker gene test with CA19-9
Description: A tumor marker gene test that will be used to stratify individuals into one of several circulating tumor marker reference ranges for CA19-9. The variants in the genes FUT3 and FUT2 affect the levels of CA19-9.
