Abstract: Method and systems for quantifying analytes in biological samples include a lateral flow assay (LFA). Integrated LFA analyte measuring devices include a first sensor that generates a signal relative to the concentration of a measured analyte. The LFA device may also include one or multiple additional sensors for auxiliary measures to assist in correcting, adjusting, or interpreting the output of the first sensor. The LFA device can cooperate with a remote database for data storage, analysis, and access.

Abstract: A method and system improving the accuracy and/or interpretability of measurements in a body fluid, such as saliva, sweat or urine involves measurement of multiple parameters in a sample with biosensors. One or more biosensors may reflect the concentration of a target biomarker, and one or more biosensors may describe a parameter of the fluid known to impact the function of the first biosensor the way the measurement of the first biosensor should be interpreted.

Abstract: A test strip for sampling a bodily fluid may include multiple layers of a substrate material, an adhesive between at least some of the multiple layers, and a microfluidic channel formed between at least some of the multiple layers. The test strip may further include multiple electrodes on one of the multiple layers, positioned and partially exposed within the microfluidic channel, an additional material positioned at or near an entrance to the microfluidic channel, to selectively limit the flow of at least one of bubbles or debris into the microfluidic channel, and at least one exit port in at least one of the multiple layers to allow for release of pressure from the test strip. In some embodiments, the test strip is a saliva analysis test strip. In some embodiments, the test strip includes multiple exit ports to prevent blockage of sample flow.

Abstract: A method for using saliva to measure at least one substance or physiological parameter of a human or animal subject may involve inserting a first end of a sensor into a handheld saliva testing device. The method may also involve receiving saliva from the subject on a second end of the sensor, moving the saliva from the second end of the sensor to the first end, and processing the saliva with the handheld saliva testing device to provide initial saliva data related to the at least one substance or physiological parameter of the subject. In some embodiments, the sensor remains inserted in the handheld device while the subject deposits saliva on the opposite, free end of the sensor.

Abstract: A method and system improving nucleic-acid testing-capacity for novel pathogens by applying family-level nucleic acid testing. The test system involves the use of an analyzer platform and single-use test cartridges which can identify the presence of one or multiple pathogens on the family-level. The test system is pro-actively stockpiled to ensure widespread availability for population screening in the event of a pandemic.

Abstract: A method of measuring an analyte in a bodily fluid sample and combining measurement data from multiple users may involve initiating a wireless connection between a handheld analyzer and a smart computing device on which an analyte analysis application has been downloaded and inserting a test strip into the handheld analyzer. The method may further involve collecting a sample of a bodily fluid on the test strip, measuring, with the handheld analyzer, a concentration of at least one analyte in the sample, wirelessly communicating the measured concentration from the handheld analyzer to the smart computing device, and displaying the measured concentration on the smart computing device. Finally, the method may involve transmitting the measured concentration to a database and organizing data including the measured concentration and at least one additional measured analyte concentration from at least one additional user on the database.

Abstract: The present invention provides a targeting device (1) for use in open, or minimally invasive, hip surgery to allow the position of the centreline of the femoral neck to be located. Also disclosed is its use in location of the centreline of the femoral neck. The targeting device comprises at least a first component (4) having a portion suitable for location on an outer surface of the femoral neck and a second component (7) having a portion suitable for marking the centreline of the femoral neck, wherein the first (4) and second (7) components are spaced apart from and parallel to one another and means is provided to alter the distance between the first (4) and second (7) components and means is provided to maintain the first (4) and second (7) components in a predetermined position relative to each other.

Abstract: A surgical device for holding and rotating an acetabular reaming head is provided, comprising a shaft having a length which runs from a first end adapted for holding an acetabular reaming head to a second end. At least part of the shaft is divergent from the axis defined by the first and second ends of the shaft, for example the shaft may include a C-shaped divergent portion. A head held by the device can therefore access the acetabulum in its true anatomical position while avoiding encroachment of the shaft on surrounding body parts.
