Study Finds Blood-based Expression Signature for Childhood Tuberculosis | GenomeWeb

NEW YORK (GenomeWeb) – An international team has uncovered a gene expression signature in host blood that appears to have potential for more accurately detecting and diagnosing tuberculosis infections in children.

"It has taken seven years and the combined efforts of clinicians and scientists in the UK, Africa and Singapore to identify this gene signature of childhood TB," Imperial College London tropical medicine researcher Michael Levin said in a statement.
