Methods are described for measuring the amount of a vitamin B2 in a sample. More specifically, mass spectrometric methods are described for detecting and quantifying vitamin B2 in a sample utilizing on-line extraction methods coupled with tandem mass spectrometric techniques.

A detection device for detecting analytes in liquid specimen is provided. The detection device comprises: a specimen chamber for collecting or storing a liquid specimen; a detecting chamber for containing a detecting element; and a through hole for transferring the liquid specimen between the specimen chamber and the detecting chamber. The through hole can be opened or self-sealed. The sealing or opening of the through hole controls whether or not the liquid specimen in the specimen chamber enters the detecting chamber via the through hole. Furthermore, a detection method is provided.

Methods and devices for diagnosing, monitoring, or determining diabetic nephropathy or an associated disorder in a mammal are described. In particular, methods and devices for diagnosing, monitoring, or determining diabetic nephropathy or an associated disorder using measured concentrations of a combination of three or more analytes in a test sample taken from the mammal are described.

Methods and kits for diagnosis and staging of shock, and especially non-septic shock are presented in which protease activities and/or volatile compounds are measured from a biological sample to so identify and/or stage shock.

The invention relates to gene polymorphisms and genetic profiles associated with an elevated or a reduced risk of a complement cascade dysregulation disease such as AMD. The invention provides methods and reagents for determination of risk, diagnosis and treatment of such diseases. In an embodiment, the present invention provides methods and reagents for determining sequence variants in the genome of an individual which facilitate assessment of risk for developing such diseases.

A device for detecting an analyte in a sample is provided, which comprises: a collecting chamber containing an opening for collecting a liquid sample; a detecting element for detecting an analyte in the liquid sample; and a lid for covering the opening of the collecting chamber. The device further comprises an indicating device thereon to indicate whether or not the lid covers at an appointed position. The operation of the device is very simple.

The invention relates to genes, gene polymorphisms, and genetic profiles associated with an elevated or a reduced risk of alternative complement cascade deregulation disease such as AMD. The invention provides methods and reagents for determination of risk, diagnosis and treatment of such diseases. In an embodiment, the present invention provides methods and reagents for determining sequence variants in the genome of a patient which facilitate assessment of risk for developing such diseases.

A method of quantitatively determining the concentration of at least one analyte in a sample by: (i) adding a portion of the sample to a first analyte assay formulation and to an analyte assay reference formulation to generate a first analyte sample and analyte reference sample and determining the concentration of the at least one analyte in the sample; and/or (ii) adding a portion of the sample to a second analyte assay formulation and determining the concentration of the at least one analyte in the sample, as well as formulations, kits of parts, systems and computer implemented methods associated with the method.

Apparatus and methods for measuring a concentration of a target molecule from a biological sample are disclosed. For example, the apparatus comprises a porous pad, which is impregnated with a solution containing at least one agent and contains an unfilled capillary matrix, a housing for the porous pad, and a membrane that covers the porous pad.
