Manual Aspiration by Monovette Reduces Hemolytic Sampling

Hemolytic blood samples are the number one cause for specimen rejection at emergency departments (ED). Triggered by unsuitable blood sampling material or incorrect handling and a related strong vacuum force, hemolytic samples often must be retaken. More...

Smartphone-Based DNA Diagnostics Detects Malaria

 There remains a substantial burden from infectious disease in low-resource rural communities, not least as a consequence of malaria. In infectious disease diagnosis, results need to be communicated rapidly to healthcare professionals once testing has been completed so that care pathways can be implemented. More...

Novel AI-Driven Cardiac Blood Test Provides Highly Accurate Prediction of One-Year Risk for Heart Attack, Stroke, or Cardiac Death

A novel, artificial intelligence (AI)-driven blood test for cardiac risk can provide highly accurate prediction of one-year risk for heart attack, stroke, or cardiac death. More...

A-D, show Candida albicans, and E-H, show C. glabrata; both the fungal color and the structure in FB 85 and CFW were clear and easily recognized from the background squamous cells compared with the KOH method (Photo courtesy of Capital Medical University)

Fluorescent Reagents Evaluated for Vulvovaginal Candidiasis Diagnosis

Vulvovaginal candidiasis (VVC) is a common vaginitis in females, which is estimated to be the second most common cause of vaginitis after bacterial vaginosis. Vulvovaginal candidiasis affects around 70%–75% of all women during their childbearing age, and is considered to be an important public health problem. More...

Electronic Nose Sensor Accurately Detects Ovarian, Pancreatic Cancers

Ovarian cancer is a cancer that forms in or on an ovary. It results in abnormal cells that have the ability to invade or spread to other parts of the body. When this process begins, there may be no or only vague symptoms. Pancreatic cancer arises when cells in the pancreas, a glandular organ behind the stomach, begin to multiply out of control and form a mass. More...

Portable, PCR-Based Assay Developed for Rapid, Multiplexed DNA Detection

The detection of specific DNA sequences is central to precision medicine, from pathogen identification to the risk assessment of human genetic diseases to disease prognosis. While technologies exist for DNA detection, they tend to be limited either in terms of multiplexing, turnaround times, quantification accuracy, or specificity for single-nucleotide differences.

A Novel Nanowell Array Sensor for POC Measurement of Stress Hormones

Researchers have constructed a microchip "nanosensor" to measure stress hormones such as cortisol in a dedicated nanowell array, which does not require molecular labels or washing steps. More...
