A system for transferring data includes an analyte test instrument (ATI) adapted to store data, a wirelessly enabled data management device (DMD) for comprehensively analyzing data, and an adaptor removably connected to the ATI for transferring data stored on the ATI to the DMD. The adaptor includes a data communication device capable of removable connection with the ATI, a microprocessor electrically connected to the data communication device, a wireless controller electrically connected to the microprocessor and a wireless transceiver electrically connected to the wireless controller. In use, data transfer is executed between the ATI and the DMD by electrically and mechanically connecting the adaptor to the ATI. Data stored on the ATI is then automatically downloaded into adaptor memory. Upon completion of the download, the user activates an externally accessible input device on the adaptor which, in turn, wirelessly transmits data from the adaptor memory to the DMD.
