With the Certitude Blood Test, you get Accuracy and Answers.
It’s finally here — a new way to screen for breast cancer as early as Stage 0.
~50% of women have dense breastsCleveland Clinic- Someone with dense breasts is 4-6x more likely to develop breast cancerDuffy et al. (Eur J Cancer 2018)
- 15% of women are high riskJiang, et al. (JCO Clin Cancer Inform 2019)
Who is this test for?
Certitude is for women who:
- Need an additional layer of screening beyond mammography
- Have dense breast tissue or inconclusive mammogram results
- Have a family history or elevated risk of breast cancer
- Want the peace of mind
What is Certitude?
Peace of Mind From a Single Blood Draw
Certitude is a simple, accurate blood test designed to screen for breast cancer — especially in women with dense breasts or who are at high risk. It’s not a replacement for mammography, but a powerful new partner in your personal screening plan.
Complements mammography for added confidence
Designed to screen for breast cancer as early as Stage 0 through protein biomarkers in your blood
Reduces anxiety for women who are high risk or those with dense breasts
How Certitude Works
Certitude analyzes specific protein patterns in your blood that are linked to breast cancer. Our advanced AI-driven technology detects these subtle changes—often before they can be seen on imaging.

How does this compare with other screening options?
Compare published sensitivity and specificity across 3D mammography, ultrasound, CEM, MRI, and Certitude for women with dense breasts. These data do not come from a head-to-head study but provide a comparative side-to-side view.
92% sensitivity
This means the test correctly finds cancer about 92 times out of 100 when cancer is truly present. In other words, it is very good at not missing cancers.
92% specificity
This means the test correctly shows a negative result about 92 times out of 100 when a person does not have cancer. It’s very good at avoiding false alarms.
>99% NPV (Negative Predictive Value)
This means that if your test result is negative, there is greater than a 99% chance you truly do not have cancer.
Works across breast density, breast cancer stages and subtypes
These numbers hold true for non-dense and dense breast, early and late stages of cancer, and different breast cancer subtypes, meaning the test performs consistently no matter the type or stage of cancer.
Getting Certitude is Simple
From Requests to Results
Certitude is available by prescription. Your healthcare provider can order it, or you can request it online through an independent telemedicine provider.
What Providers Say
"Too many women with dense breasts are left without clear answers after their annual screening. Certitude offers something we’ve needed — a simple, accessible test that can help detect cancer earlier and provide greater clarity. Certitude represents a meaningful and long-awaited advancement — one that can help physicians intervene sooner, reduce anxiety, and guide more confident clinical decision-making."
"Mammography remains our most powerful population-level screening tool, but it is not perfect — particularly for the many women with dense breasts. A blood-based test that can identify molecular signals of cancer before they’re visible on imaging has the potential to fundamentally reshape the breast cancer screening paradigm."
