U.S. guidelines recommend newer tests to diagnose TB (post)
ARLINGTON, Va., December 8 – Patients at risk for latent or active tuberculosis (TB) infection should be assessed with newer tests, including interferon-gamma release assays (IGRAs) and molecular diagnostics, recommend guidelines on TB diagnosis developed by the American Thoracic Society (ATS), Infectious Diseases Society of America (IDSA) and Centers for Disease Control and Prevention (CDC) and published in the journal Clinical Infectious Diseases. Advances in testing prompted the first new guidelines on TB diagnosis in 17 years.

Abstract
Xpert diagnostic tool increases TB detection rate, treatment initiation (post)
New research found that a community-based strategy involving a nucleic-acid amplification test that can detect both Mycobacterium tuberculosis DNA and rifampicin resistance increased the rate of tuberculosis case detection and early treatment initiation.
Improving the accuracy of TB testing (post)
Tuberculosis (TB) affects some 35-million people globally. In 2009 testing for TB using molecular diagnostics proved a game-changer for national TB programmes.

Abstract
WHO calls for list of essential diagnostics (post)
Last June, a Perspective piece in the New England Journal of Medicine noted the critical place that the World Health Organization’s list of Essential Medicines had assumed in global health policy and responses — donors, governments and insurers were all more likely to invest in promoting accessibility of medicines that were on the list. The list includes medicines critical to meeting individual and public health needs, treating illnesses and curtailing their transmission. The authors, representing health, research and academic institutions from Ann Arbor, Atlanta, Baltimore, Kampala, Uganda and more, noted a missing piece that would allow better use of the medicines on the list — a list of diagnostic tools that would ensure they were used appropriately, improving care and reducing the risks of antimicrobial resistance. Time for a Model List of Essential Diagnostics also noted some of the other benefits — improved surveillance of outbreaks that have recently included Zika and Ebola, and improved, more consistent awareness and management of known health challenges.

Simple test may predict which children develop severe TB, researcher says (post)
A Stanford investigator and his colleagues found that a screening test for tuberculosis was a good predictor of whether children infected with the bacteria would become sick.
Innovation, research tackle TB challenges (post)
SEATTLE – In the halting progress against tuberculosis in people living with HIV, advances in both diagnosis and effective treatment have come with gaps and caveats, highlighted, and then answered with research presented last week in sessions and press conferences dedicated to tuberculosis.
