New Method Detects Different Types of Dangerous Viruses or Disease Markers from Single Measurement

Scientists have developed a method to detect viruses in very small volumes. The work follows a successful Innovate UK project developing graphene for use in biosensors – devices that can detect tiny levels of disease markers. Biosensors such as this could be used at the point-of-care - opening effective healthcare in difficult-to-reach settings. More...

Elecsys Androstenedione Immunoassay Evaluated and Compared

Androstenedione (ASD) is a biomarker used in the diagnostic workup of hyperandrogenism, congenital adrenal hyperplasia, premature adrenarche, and polycystic ovary syndrome (PCOS). Androstenedione is the precursor of testosterone and estrone and is produced in the gonads and adrenal glands. More...

A New Image for Cell Sorting Introduced

Methods that physically separate cells of interest on the basis of measurable characteristics have numerous uses in clinical studies and applications, including cellular therapies. Cells can also be sorted on the basis of signals from extrinsic probes. More...

Wearable Lab on the Skin Simultaneously Monitors Glucose, Alcohol and Lactate in Real-Time

Engineers have developed a prototype of a wearable that can continuously monitor several health stats - glucose, alcohol, and lactate levels - simultaneously in real-time. More...

Novel Automated Procalcitonin Immunoassay Compared with Four Different Assays

Procalcitonin (PCT) is an important biomarker of sepsis and respiratory infections. An increase in PCT expression in parenchymal tissue can typically be observed in severe bacterial, but not or significantly less, respectively, in viral infections; thus, measurement of plasma PCT concentrations is an important diagnostic tool for clinicians to distinguish between infections from a bacterial versus viral origin.

Magnetic Needle Performs Less Invasive, More Precise Surgery and Diagnostic Tests

A team of researchers at the Johns Hopkins Whiting School of Engineering (Baltimore, MD, USA) have demonstrated for the first time that untethered magnetic needles can be forceful enough to accomplish surgery. The researchers call their device the "Pulse Actuated Collisions for Tissue-penetrating Needle," or MPACT-Needle. More...

Electronic Nose Technology May Facilitate Accurate Diagnosis of Sarcoidosis

Sarcoidosis is a granulomatous inflammatory disease without a known cause that can affect roughly any organ. The lungs are involved in the vast majority of patients (89% to 99%). Diagnosis can be challenging because no standardized diagnostic procedure exists. The three major criteria for diagnosis are compatible clinical features, pathology tissue assessment, and exclusion of other granulomatous diagnoses. More...
