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...

New Technology Can Diagnose Infections in Minutes

The detection and identification of bacteria currently rely on enrichment steps such as bacterial culture and nucleic acid amplification to increase the concentration of target analytes. These steps increase assay time, cost and complexity, making it difficult to realize a truly rapid point-of-care test. More...

Leukocyte Differential on Hematology Analyzer Compared and Evaluated

A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood. The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells). More...

Rapid Diagnostic Tests Evaluated for Chronic Chagas Disease Patients

Chagas is a disease caused by the parasite Trypanosoma cruzi, and is one of the most important public health concerns affecting the population of Latin America. This disease presents an acute phase that generally goes undiagnosed and a chronic phase with cardiac manifests principally, is diagnosed through serological tests that are generally not available. More...

Point-of-Care Testing Evaluated for Early Coagulopathy Diagnosis

Hemorrhage and coagulopathy are particularly relevant complications and are often connected to injuries, surgical interventions, serious diseases, anticoagulant medication or pregnancy/delivery. Acute bleeding requires fast and targeted therapy and therefore, knowledge of the patient's potential to form a clot is crucial. More...
