77354-9Noninvasive colorectal cancer DNA and occult blood screening [Presence] in StoolActive

Term Description

This term was created for, but is not limited in use to, Exact Sciences' Cologuard DNA screening test for colorectal cancer. The Cologuard algorithm includes two laboratory procedures performed on a single stool specimen: 1) detection and quantification of fecal occult blood using ELISA; and 2) detection of multiple genetic biomarkers (NDRG4 and BMP3 methylation targets, seven KRAS point mutations, and beta actin as a proxy for the total amount of human DNA in each sample) using magnetic bead based oligonucleotide hybrid capture to isolate the biomarkers followed by quantitative real-time target and signal amplification. The occult blood and genetic biomarker results are subsequently entered into a logistic regression model, and the results from this model are used to calculate a composite score from which the final binary result (positive, negative) is determined.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
