The invention relates to methods and systems for removal of pathogens from blood or blood products. The invention further relates to methods and systems for treatment and diagnosis of infection in the blood and/or sepsis in a patient in need thereof.

The present disclosure provides compositions, methods, kits and systems for detecting antibodies in a biological sample. In some embodiments, methods/systems are particularly useful for detecting antibodies in patients against pathogen-inactivating compound treated RBCs.

A method includes estimating a value of a parameter indicative of an age or lifespan of a population of red blood cells of a subject, estimating a value of average glucose (AG) of the subject based on (i) the value of the parameter and (ii) a value indicative of an amount of glycated hemoglobin (HbA1c) of the subject, and providing information for treatment or diagnosis of a hyperglycemia condition of the subject based on the estimated value of AG.

The systems and methods contained herein are directed toward automated analysis of agglutination reactions to determine properties of materials, including viruses and vaccines thereto. Advanced digital imaging and processing techniques are used to determine the presence or absence of viruses or antibodies within a fluid sample. The systems and methods are versatile, and can be used to determine specific properties of biomaterials and viruses, such as titer value, concentration, genotype, phenotype, serotype, vaccine efficacy, viral resistance and other properties of relevance in the medical, research and development fields. Also provided are systems and methods of standardization, repeatability, and data storage and transmittal to reduce errors and subjectivity inherent to conventional assays characterized by human readers.

A joint point-of-care testing (POCT) analyzer, and a system comprising an analyzer and a cartridge, for measuring one or more analyte quantities per unit volume of blood and one or more formed element quantities per unit volume of blood, is described. Examples of formed elements of blood are red blood cells and white blood cells, and cell counts are determined by imaging using a two-dimensional multi-channel detector. Examples of analytes are hemoglobin and bilirubin, and hemoglobin and bilirubin concentrations are determined by spectroscopy using a one-dimensional multi-channel detector. Other examples of analytes are electrolytes, and electrolyte concentrations may be determined using biosensors incorporated in the cartridges.
