TEST DETAILS

Genetic tests yield a wealth of information – some of it unexpected. Consult with your healthcare provider, speak with your family, and ensure you have access to the latest information before proceeding. The field of genetics is always evolving – and so are we.

TEST FORMS, OPTIONS, AND ORDERING DETAILS

Prosigna is ordered under the guidance of a healthcare provider only. Contact us if you need help or have questions.

Frequently Asked Questions for the Test

Can I have a sample taken for the Prosigna® test at a LifeLabs Patient Service Centre?

No. Prosigna® requires a tumour tissue (histology) sample from your physician or hospital.

This type of sample is usually obtained during surgery. If you and your physician are considering this test, you must request the sample prior to your surgery. Some hospital pathology labs keep post-surgical samples on “file.” Your physician may be able to submit one of these samples for Prosigna.

Prosigna has proven prognostic significance in two clinical studies with more than 2,400 patients. One of these studies, the TransATAC study, compared Prosigna® with other commercial assay tests and found the following:

“For post-menopausal women with node-negative, hormone receptor-positive, HER2-negative early stage breast cancer, the study found that Prosigna® provided the most accurate prognostic information of all four multigene expression profiles tested as measured by the statistical measure known as the likelihood ratio. The study further found that Prosigna® also provided the most accurate differentiation between low and high risk patients as compared to the other genomic tests. Low-risk women as identified by Prosigna® had a 3% risk of DR [distant recurrence] over 10 years, the lowest rates of DR for all genomic tests that were studied. In contrast, high risk women as identified by Prosigna® had on average a 33% chance of distant recurrence by 10 years.”
