NEW YORK (GenomeWeb) – A group of Italian researchers have validated a microRNA-based blood test for early detection of lung cancer that they hope to introduce as a first-line tool that doctors can use to select which patients should go on to receive additional screening with low-dose computed tomography (LDCT).

The so-called miR-Test analyzes patients' serum based on a 13-miRNA signature and deems them either positive or negative for lung cancer. miRNAs are frequently abnormally expressed in tumors, and this irregularity shows up in miRNA profiles in serum and plasma.
