Publication number: 20130302787Abstract: A device for extraction or isolation of an analyte, such as a nucleic acid, a protein, or a cell, from a sample, and in particular from a biological sample, is described. Methods of using the device are also described.

Publication number: 20130244315Abstract: An analytical device for performing an assay to determine the presence or approximate quantity of at least one analyte in a liquid sample is described. The device is manufactured to include an integrated desiccant within at least a test strip of the device. Addition of an integrated desiccant within the device improves signal to noise ratio, eases the manufacturing process, and saves in cost of production of the device.Type: ApplicationFiled: May 6, 2013Publication date: September 19, 2013Applicant: QUIDEL CORPORATIONInventors: Kevin J. Kirby, Sarah Dennison

Publication number: 20130230845Abstract: A system comprised of an apparatus and a test device is described. The test device and the apparatus are designed to interact to determine the presence or absence of an analyte of interest in a sample placed on the test device. The test device and apparatus interact to provide a timer feature for determining a test device specific adjustable cut-off value that is used to ascertain whether signal from a test line in the device corresponds to a positive or negative results, irrespective of the time elapsed since placement of sample on the test device. The adjustable cut-off value renders the system relatively insensitive to incubation time of the test device, where if the incubation time is shorter or longer than needed for accuracy of a test result, the analyzer will report an invalid result, thus preventing the reporting of an incorrect (false negative or false positive) result.Type: ApplicationFiled: March 1, 2013Publication date: September 5, 2013Applicant: Quidel CorporationInventors: Richard L. Egan, Michael Jon Hale

Publication number: 20130196337Abstract: Methods, compositions and kits for detecting Group A streptococcus in a biological sample are described. More particularly, the present disclosure provides an immunoassay in which the specificity of detection of Group A streptococcus is enhanced by addition of N-acetyl-D-glucosamine. These methods, compositions and kits are useful in convenient, reliable and early diagnosis of streptococcal infection in a human subject.Type: ApplicationFiled: July 31, 2012Publication date: August 1, 2013Applicant: Quidel CorporationInventors: Peter Yan-Guo Ren, Jason McClure, Kevin S.

Patent number: 8202734Abstract: A test device and method for determining the presence or absence of an analyte in a fluid sample, the test device including a support bearing a mark thereon, and a matrix defining an axial flow path. In operation, an observation area in the test device becomes transparent, thereby allowing the user to view a mark that is present on a support that is disposed beneath the observation area. Typically, the mark on the underlying support is configured as a minus (?) sign. In the absence of analyte in the sample, the test device presents a negative result as a minus (?) signal. In the presence of analyte in the sample, however, the mark operates in concert with a perpendicular test line on the observation area to present a positive result as a plus (+) signal that is visible to the user.Type: GrantFiled: April 14, 2009Date of Patent: June 19, 2012Assignee: Quidel CorporationInventors: Jeremy Jerome, Mark Daquipa, Bruce Jacono, Hans Boehringer

Publication number: 20120021528Abstract: A test device and method for determining the presence or absence of one or more analytes in a fluid sample, the test device including a support or member bearing a mark thereon, and a matrix or member containing a capture zone. In operation, an observation area in the test device becomes transparent, thereby allowing the user to view a mark that is present on a support that is disposed beneath the observation area. Typically, the mark on the underlying support is configured as a minus (?) sign. In the absence of analyte in the sample, the test device presents a negative result as a minus (?) signal. In the presence of analyte in the sample, however, the mark operates in concert with a perpendicular test line on the observation area to present a positive result as a plus (+) signal that is visible to the user.Type: ApplicationFiled: October 3, 2011Publication date: January 26, 2012Applicant: QUIDEL CORPORATIONInventors: Jeremy Jerome, Mark Daquipa, Bruce Jacono, Hans Boehringer, Paul Lambotte, Paul J.
