A universal rapid diagnostics test reader is disclosed and described herein that includes a set of control electronics, a digital camera component, an illumination component, a housing component, and a rapid diagnostics test tray, wherein the tray can hold at least one rapid diagnostics test having a shape and a size in a fixed position relative to the digital camera component and the illumination component, and wherein the reader can accommodate more than one different rapid diagnostics test. Methods are also disclosed that include: providing at least one first rapid diagnostics test having a first physical size, first feature and first format; providing at least one second rapid diagnostics test having a second physical size, second feature and second format; inserting the first rapid diagnostics test in a universal rapid diagnostics test reader; analyzing the first rapid diagnostics test using the universal rapid diagnostics test reader; removing the first rapid diagnostics test from the reader; inserting the second rapid diagnostics test in a universal rapid diagnostics test reader without any mechanical adjustments of the reader or without the use of any additional parts or additional inserts; and analyzing the second rapid diagnostics test using the universal rapid diagnostics test reader.

Universal rapid diagnostic test reader with trans-visual sensitivity

A portable colorimetric assay system includes an opto-mechanical reader configured to be detachably mounted to a mobile phone having a camera or other camera-containing portable electronic device. The opto-mechanical reader includes one or more light sources configured to illuminate a test sample holder and control sample holder disposed in the opto-mechanical reader along an optical path aligned with a camera of the mobile phone or other camera-containing portable electronic device. One or more serum separation membranes are disposed in the opto-mechanical reader and define a sample receiving pad configured to receive a blood sample. A moveable serum collection membrane is membrane is also disposed in the reader and is configured to contact the sample receiving pad in a first position and moveable to a second position where the serum collection membrane is disposed inside the test sample holder.

System and method for measuring serum phosphate levels using portable reader device

A micro-plate reader for use with a portable electronic device having a camera includes an opto-mechanical attachment configured to attach/detach to the portable electronic device and includes an array of illumination sources. A slot in the opto-mechanical attachment is dimensioned to receive an optically transparent plate containing an array of wells. Optical fibers are located in the opto-mechanical attachment and transmit light from each well to a reduced size header having, wherein the fiber array in the header has a cross-sectional area that is &#x2264;10&#xd7; the cross-sectional area of the wells in the plate. A lens located in the opto-mechanical attachment transmits light from the header fibers to the camera. Software executed on the portable electronic device or other computer is used to process the images to generate qualitative clinical determinations and/or quantitative index values for the separate wells.

Micro-plate reader for ELISA testing

A system for measuring chlorophyll concentration in a leaf sample includes a leaf-holding illuminator device with a main body containing a power source, a plurality of switchable light sources emitting light at different spectra (e.g., red and white light from a broadband light source), and a cap detachably secured to the main body using one or more fastening means. The leaf sample is interposed between the main body and the cap and held in place during imaging. The system includes a mobile electronic device having a camera configured to capture an image of the leaf illuminated by the plurality of switchable light sources, the mobile electronic device having wireless connectivity to a network and an application contained therein configured to transfer the images to a remote sever or computer via the network for data processing. A final chlorophyll index value is calculated based on the transferred images.
