POCT results can be received from the POCT device at a mobile computing device. The mobile computing device and the POCT device are located outside the LIS environment, for example, at a physician office or remote clinic. The mobile computing device can use its own data broker to configure low-level instrument protocol data from the POCT device for secured transmission over a wide-area network infrastructure. The POCT results can be subsequently received in the LIS environment and provided to the LIS to transparently populate an electronic medical record (EMR) with the POCT results. In some examples, the LIS or a hospital information system can also update a point-of-care EMR. ## Claims ### Claim 1 A system comprising: a non-transitory computer-readable medium including computer program code to provide a transparent secure link for point-of-care testing (POCT) devices;
