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.

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...

Serum Based Antigen Test Detects Childhood Tuberculosis

Approximately one million children develop tuberculosis (TB) and 205,000 die of TB-related causes each year. Eighty percent of these deaths occur in children < 5 years old, with the majority (96%) of deaths occurring among children who did not receive treatment, where missed diagnoses are likely responsible for undertreatment. More...

RPA-LF Assay Evaluated for Cutaneous Leishmaniasis in Colombia

Cutaneous leishmaniasis (CL) is a recognized public health challenge in the Americas, with an average of 55,000 cases per year between 2001 and 2018 in 17 countries of the region. Most cases (79.4%) have been acquired in and continue to occur in rural areas. More...
