Blood test for asthma may follow discovery of biomarkers

STATE COLLEGE, Pa., April 13 (UPI) -- There is no definitive test for asthma, with most diagnoses based on history and breathing tests, both of which researchers say lack definition and depend on patients having attacks before any type of treatment.
Researchers at Penn State University found microRNAs, or miRNAs, in the blood can indicate whether patients have asthma or another similar condition that includes lung inflammation, according to a new study.....

Discovery opens the door to better asthma detection and treatment

Asthma is a disease that affects some 25 million people in the US alone, but there's currently no definitive test for diagnosing it. New research could change that, with scientists at the Penn State College of Medicine identifying molecules that circulate in patients' blood, signalling that they have the disease. Not only could the breakthrough lead to a new diagnostic test, but it could also allow for the development of new, more targeted treatments.....

New asthma biomarkers discovered, could ease detection

People with asthma have telltale molecules circulating in their blood, say researchers at Penn State College of Medicine. The discovery could lead to the first diagnostic blood test for asthma, as well as more targeted treatments for the condition.....
