Active tuberculosis can be rapidly identified in patients with negative sputum tests by a new method, according to European researchers.

Researchers from the Albert Einstein College of Medicine and The University of Pittsburgh have developed an onsite method to quickly diagnose tuberculosis (TB) and expose the deadly drug-resistant strains that can mingle undetected with treatable TB strains.

A recently introduced blood test can reveal which patients may develop active tuberculosis (TB) much more precisely than the 100-year old TB skin test, according to a new study published today in the journal Annals of Internal Medicine.

The health care system in California could save nearly $1.3 million a year with few adverse public health effects if it discontinued universal tuberculosis skin testing of children entering kindergarten, according to a new study by researchers at the University of California, San Francisco.

Blood-based antibody detection tests for tuberculosis (TB) have come under the spotlight in a research article published in PLoS Medicine. The authors, based in North America and Europe, conducted a "systematic review and meta-analysis" of studies that have been conducted on the accuracy of the tests, and have concluded that they do not perform well in comparison to standard methods.

A new test for diagnosing tuberculosis offers a quick and simple alternative to existing three-day methods, according to research published today in the journal Clinical Infectious Diseases.
