An analytical method for measuring degradation of iron-carbohydrate complex for intravenous injection may include formulating a reaction solution comprising an iron-carbohydrate complex for intravenous injection, a reducing agent, and a complexing agent. The method may further include measuring absorbance spectral absorbance of an iron-complexing agent species including all or a portion of the complexing agent and iron released from the iron-carbohydrate complex that has been reduced by the reducing agent. Example complexing agents may include 1,10 phenanthroline or ferrozine. An example, iron-carbohydrate complex may be iron sucrose injection.

Methods of detecting aberrant results caused by delivery issues for a polyhapten reagent in the context of immunoassays are disclosed.

The present invention describes a method of performing immunoassay measurements on whole blood samples for biomarker quantification. These tests are routinely performed on serum or plasma separated from whole blood samples. Prior art also involves application of complex multi-component assays or methods using insoluble particles for these measurements. A solution capable of working on whole blood samples, offering advantages in assay simplicity, cost-effectiveness and shortened measurement times was desired. The present invention solves these issues using simple immunoturbidimetry for whole blood samples without relying on particle enhancement of the reaction. To achieve this goal the agglutination reaction between antibodies and antigens is performed, measured and evaluated according to the disclosed method for whole blood assays.

Exemplified methods and systems facilitate presentation of data derived from measurements of endotoxins in fluid samples. In particular, the exemplified methods and systems facilitate presentation of such measurements in a graphical user interface and/or in a report for endotoxin concentrations in a fluid sample. The presentation facilitates a unified and intuitive graphic visualization that are presented within a single interactive interface and/or report.

Disclosed herein are methods for rapid detection of suspension of a blood sample from a subject and methods for improving the processing time of a point of care blood analysis. Specifically, the disclosed methods provide a rapid detection of hemoglobin concentration, more specifically glycated hemoglobin A1c, and determination of sugar concentration in the blood sample from the subject. Further disclosed herein are methods for rapidly diagnosing diabetes in a subject.

Systems and methods for tracking healing progress of multiple adjacent wounds are provided. In one embodiment, a system may include a processor configured to receive a first image of a plurality of adjacent wounds near a form of colorized surface having colored reference elements, determine colors of the plurality of wounds, correct for local illumination conditions, receive a second image of the plurality of wounds near the form of colorized surface, to determine second colors of the plurality of wounds in the second image, match each of the plurality of wounds in the second image to a wound of the plurality of wounds in the first image, and determine an indicator of the healing progress for each of the plurality of wounds based on changes between the first image and the second image.

The invention relates to a method for controlling an enzymatic pre-treatment process, e.g. a mashing process. The method allows for accurate determination of specific sugar molecules as well as the average length of the sugar chains in real-time during e.g. a mashing process. Further information on e.g. the concentration of dissolved protein and free amino acids can also be obtained simultaneously. The method comprises the use of an infrared (IR) spectometer for continuously measuring attenuated total reflectance (ATR) IR spectra of samples obtained during pre-treatment of biomass.
