20150031135 | CALIBRATION METHOD FOR REAGENT CARD ANALYZERS - A method for calibrating an imager of a reagent analyzer, comprises positioning a dry reagent pad at a first read position in a field of view of the imager, the first read position illuminated by an illumination source with a first intensity, detecting a reference optical signal by the imager, indicative of a first reflectance value of the dry reagent pad at the first read position, positioning the dry reagent pad at a second read position, the second read position illuminated with a second intensity different from the first intensity, detecting a first optical signal by the imager, indicative of a second reflectance value of the dry reagent pad at the second read position, and calculating, by a processor, a calibration factor for the dry reagent pad at the second read position based on a difference between the reference optical signal and the first optical signal. | 01-29-2015 |
20150104876 | RELEASE REAGENT FOR VITAMIN D COMPOUNDS - The present invention concerns a reagent composition for releasing vitamin D compounds bound to vitamin D-binding protein, a method for the detection of a 25-hydroxyvitamin D compound in which the 25-hydroxyvitamin D compound is released from vitamin D-binding protein using this reagent and the mixture obtained in this manner is analyzed, the use of the reagent to release vitamin D compounds as well as a kit for detecting 25-hydroxyvitamin D which contains the reagent for releasing vitamin D compounds in addition to the usual immunological reagents. | 04-16-2015 |
20150132854 | Tuned Synthetic Dendrimer Calibrants for Mass Spectrometry - Provided are synthetic dendrimer calibrants for mass spectrometry. The calibrants are distinguished by their relative ease and rapidity of synthesis, comparatively low cost, long shelf life, high purity, and amenability to batch synthesis as mixtures. The latter characteristic enables parallel preparation of higher molecular weight compounds displaying useful distributions of discrete molecular weights, thereby providing multi-point mass spectrometry calibration standards. Methods of making, tuning and using said calibrants are provided. | 05-14-2015 |
20150147815 | CELL FREE DNA DIAGNOSTIC TESTING STANDARDS - Embodiments of the invention include methods and compositions for producing proficiency testing standards for noninvasive prenatal genetic diagnostics and for the detection and monitoring of cancer. The compositions can comprise a plurality of different nucleosomal DNA fragments derived from either primary cells or cell lines. The amount of the different nucleosomal DNA fragments can be varied so as to simulate naturally occurring cell free DNA samples obtained from the blood of the pregnant woman or naturally occurring cell free DNA samples obtained from the blood of cancer patients. | 05-28-2015 |
