IVD instruments are designed for various qualitative or quantitative diagnostic procedures, commonly called assays, in assessing or measuring the target entity out of the samples. For different assays, IVD instruments are designed with the goal to automate the process, combining and streamlining labor-intensive steps. Based on their applications, these steps could be combined in one self-contained platform, in several discrete platforms, or a combination of both, depending on the application’s needs. Furthermore, some platforms use modularization, starting with minimum modules and then adding modules as the needs grow. This enables laboratories to pick and choose optional modules as needed. With modular design in mind and in order to be most effective, an embedded computing platform used in an IVD instrument needs to be easy-to-configure and easy-to-expand.
