Embodiments of the present disclosure disclose a distributed ledger technology (e.g., blockchain)-based system that provides tools and mechanisms to place users in control of their data. In embodiments, the system may include a platform device configured to initiate a connection with a lab test service provider whose systems (e.g., computer systems) may store data pertaining to the user. In embodiments, the platform device is configured to secure the data stored at the lab test service provider by facilitating deployment of that data into a distributed ledger. Once the data is secured in the distributed ledger, the platform device may be configured to provide controlled distribution or sharing of the secured data with other users or other third-party systems.
