  • Publication number: 20240274234
    Abstract: Systems and methods for pathogenic genetic sequence identification are provided. A sample of genetic material may be sequenced by a sequencing system. The genetic sequence may be filtered based on sequences designated as not being of interest. Such filtering may yield a filtered sequence subset, which may be compared to sequences that are designated as being of interest. One or more portions of the filtered sequence may be identified as matching the sequences of interest within a predetermined threshold for the sample. Data regarding the matching portions may further be compressed and securely stored in memory. Access to the securely stored data may be limited to authorized persons as defined by applicable rules and policies.
