MastoCheck is a blood test that can easily screen for breast cancer at an early stage. Breast cancer is diagnosed early by substituting the quantitative values of three types of protein biomarkers in the blood, which are closely related to breast cancer, into a unique, patented algorithm.
An innovative and convenient test method that detects early breast cancer with an accuracy of 92% (based on the patent) by using only a very small amount of blood.
Bertis has developed multiple markers that can detect early breast cancer with an accuracy of 92% through identification of multiple proteins that are expressed sensitively in early-stage breast cancer and combination of certain proteins that demonstrated high accuracy
and reproducibility among these combinations.
DEVELOPMENT PROCESS:
- MASTOCHECK was developed by a team led by Professor Dong-Young Noh, a world-renowned authority on breast cancer, of Seoul National University.
- After analyzing approximately 600,000 proteins and selecting 3 markers exhibiting optimal accuracy,
the highest accuracy was obtained by adding Bertis�¢?? own algorithm that enhances accuracy.
- After several years of repeated validation work, a medical device product license was obtained from the MFDS in January 2019. To date (as of September 2023), MASTOCHECK has been introduced to about 400 hospitals and screening institutions nationwide, with priority given to large screening institutions.
Proteomics-based early diagnosis determines the presence of disease by identifying proteins that are specifically expressed in diseases and using these as biomarkers to measure the quantitative values of the relevant proteins in blood.
Proteomics analysis has been assessed as highly likely to be used as a universal primary screening method because analysis can be performed even with trace samples, such as a few drops of blood.
High diagnostic accuracy :
Quantitative values of biomarkers are measured and entered in a unique algorithm with applied AI.
Convenience :
No burden of inconvenience caused due to the use of a separate diagnostic device other than blood sampling
Efficiency:
Provides diagnosis opportunities to more people in situations where personnel and devices are limited
