New Medical Laboratory-in-a-Suitcase Detects Ebola in 15 Minutes or Less

Demand for a rapid, accurate diagnostic solution to combat Ebola is motivating research teams in many countries to develop solutions that can be put to immediate use

In West Africa, the outbreak of Ebola in several countries motivated researchers in Germany to develop a fast, accurate, and inexpensive test that could be performed in patient care settings without the need for a centralized medical laboratory.

In these West African countries, lack of electricity and reliable cold storage or diagnostic equipment handicaps clinical laboratory technicians who are testing patients for the Ebola virus. A new test developed by researchers at the German Primate Center (DPZ) in Göttingen, Germany, cuts the time to answer an Ebola diagnosis to just 15 minutes. It requires no electricity and is portable. Previously, the fastest Ebola diagnostics test took three hours to get results and required transporting samples to often-distant medical laboratories.

New Insights into Genetic Mechanisms Common to Humans and Simpler Species May Form the Basis for New Diagnostic Tests Performed by Clinical Pathology Laboratories

Scientists participating in the modENCORE study have the goal of understanding the causes of hereditary genetic diseases in humans

New discoveries about the interaction of genes and transcription factors in creating different types of RNA will be of interest to pathologists and clinical chemists performing genetic tests and molecular diagnostic assays in their medical laboratories.

The goal of this research is to better understand hereditary genetic disease in humans. The new knowledge is based on studies of the common fruit fly, or Drosophila melanogaster (D. Melanogaster), and to a lesser extent a tiny worm Caenorhabditis elegans (C. elegans). Both have been used as research models to study the human condition.

Researchers Say It’s Time to Reclassify Cancerous Tumors Based on Their Molecular Makeup; New System Suggested Would Affect Pathologists’

More than 12 cancer types were studied in this project, which is a part of The Cancer Genome Atlas

New molecular and genetic knowledge is making it possible for researchers to propose a new system for classifying tumors. Upon implementation, such a system will give oncologists and pathologists, and clinical laboratory professionals a new tool to improve how they diagnose and treat cancer patients.

Tumor categories—defined by cell types instead of where they are found in the body—may lead to more accurate diagnoses and more effective treatments for one in 10 patients, according to the recent study. It was summarized in a Medline Plus Health News By Date story posted on the National Institutes of Health (NIH) website. (more…)

Thomas Jefferson University Study Finds Critical Weakness in Commercially Manufactured Exome-Capture Test Kits Used by Some Medical Laboratories

The four exome test kits examined as part of this study failed to deliver quality results, particularly because they often missed some disease-causing mutations altogether

Human exome sequencing is gaining favor among medical laboratories wanting to use this information for clinical purposes. However, the accuracy of some exome-capture test kits available on the market today has come under question.

A team from the Thomas Jefferson University in Philadelphia surveyed the potential false-negative rate of mutations in 56 disease-causing genes produced by four different commercially available human exome-capture test kits. The researchers found that these test kits failed to deliver quality results, sometimes missing mutations altogether, noted a report published by Medical Daily. (more…)

New Study of Fruit Fly Genome Reveals Complexity of RNA and Provides a Model for Studying Mechanisms for Hereditary Diseases in Humans

This investigation of the fruit fly’s transcriptome—the complete collection of the genome’s RNA—unearthed thousands of new genes, transcripts, and proteins

Scientists have teased another level of information out of the genome. This time, the new insights were developed from studies of the fruit fly’s transcriptome. This knowledge will give pathologists another channel of information that may be useful in developing assays to support more precise diagnosis and therapeutic decisions.

The findings were published in a recent issue of Nature. The study focused on the transcriptome—a complete collection of the genome’s RNA—of the common fruit fly−Drosophila melangogaster. (more…)
