Abstract:
The invention provides methods for the sensitive detection of cardiac troponin. Such methods are used in diagnosis, prognosis, and determination of methods of treatment in conditions that involve release of cardiac troponin.
Abstract:
Disclosed herein is a method for improving the precision of a test result from an instrument with an optical system that detects a signal. The method comprises including in the instrument a normalization target disposed directly or indirectly in the optical path of the optical system. Also disclosed are instruments comprising a normalization target, and systems comprising such an instrument and a test device that receives a sample suspected of containing an analyte.
Abstract:
The invention provides methods, compositions, kits, and systems for the sensitive detection of cardiac troponin. Such methods, compositions, kits, and systems are useful in diagnosis, prognosis, and determination of methods of treatment in conditions that involve release of cardiac troponin.
Abstract:
A semi-automated biological sample analyzer and subsystems are provided to simultaneously perform a plurality of enzyme immuno assays for himan IgE class antibodies specific to a panel of preselected allergens in each of a plurality of biological samples. A carousel is provided to position and hold a plurality of reaction cartridges. Each reaction cartridge includes a plurality of isolated test sites formed in a two dimensional array in a solid phase binding layer contained within a reaction well which is adapted to contain a biological sample to be assayed. The carousel and cartridges contain structures which cooperate to precisely position the cartridges in each of three separate dimensions so that each cartridge is positioned uniformly. An optical reader operating on a principle of diffuse reflectance is provided to read the results of the assays from each test site of each cartridge. Also provided is a subsystem which provides predetermined lot-specific assay calibration data which is useful for normalizing the results of various assays with respect to predetermined common standard values.
Abstract:
A portable, battery powered instrument for measuring the amount of material dissolved in a liquid solution employs electro-optic technology based on the Beer-Lambert Law. A sample probe (14) is inserted in a solution to be measured. The results of the measurement are displayed on a display (22). The displayed results are frozen for a predetermined period of time at the expiration of which, the power is turned off to conserve battery power.
