A method for displaying correlated data of a patient includes receiving, using a hardware processor, incoming lab test data at a central server. The incoming lab test data includes a plurality of different original formats and is stored on the central server in the original formats received. The lab test data is then converted into a unified format to obtain unified format lab test data. The unified format lab test data is then correlated, using the hardware processor, based on a healthcare identification code to obtain correlated data and is displayed as a single document.
