Abstract: A modular hand-held point of care testing system, which includes a plurality of different assay adapters configured to receive a plurality of different assay devices that perform assays on one or more samples; a shared door that that interchangeably receives the plurality of different assay adapters; wherein at least two of the plurality of assay adapters or at least two of the assay devices comprise different identifiers that distinguish the assays from each other; an apparatus comprising a portable frame configured to interchangeably receive the shared door and a means for decoding the different identifiers when received by the frame; and a means for reading assay results.

Abstract: A hand-held point of care monitoring system that includes a plurality of assay modules configured to receive different assay devices that perform assays on one or more samples. At least two of the assay modules or at least two of the assay devices have different identifiers that identify the assays. The system also includes an apparatus having a portable frame configured to interchangeably receive the plurality of assay modules in a same port; a means for decoding the different identifiers when received by the frame; and a means for reading assay results.

Abstract: Provided herein is an assay apparatus comprising at least one assay module; and a portable frame adapted to releasably retain the at least one assay module. The at least one assay module is adapted to perform at least one assay. The assay module comprises a sample receiver and an assay device operatively associated with the sample receiver. In some embodiments, the assay apparatus further comprises at least one functional module releasably retained by the portable frame. The functional module is operatively associated with the assay module when retained by the portable frame.
