How the blood test works and how it is used

The IvyGene® test measures the methylation status of cell-free DNA extracted from blood samples at target sites that have been demonstrated to be hypermethylated when certain cancers are present. Test results are reported as a quantitative IvyGene® Score, which indicates the methylation status of the target sites. The IvyGene® Score is calculated as a composite average of cell-free DNA that is methylated at the target sites as a fraction of the total cell-free DNA present.

An IvyGene Score of 1-19 is considered normal.  An IvyGene Score of 20 or greater is considered elevated.

Sensitivity and Specificity of the IvyGene test are approximately 92%.  These numbers are subject to change as the use for the IvyGene test to confirm the presence of additional cancer types are investigated.

The IvyGene® test is an adjunct clinical test that is intended to be based on the independent medical judgement of the ordering physician in conjunction with the patient’s complete medical history and the results of standard of care testing. The IvyGene® Test has been validated with four (4) cancer tissues of origin: breast, colon, liver and lung cancers. The presence of other cancer types may also result in an elevated IvyGene® Score. A large-scale clinical trial to demonstrate the efficacy of the IvyGene® Test as a cancer screening test has not been conducted. Cancer screening is not an approved utility of the IvyGene® test.
