Biomarker Identifies Asthma Aspirin Intolerance Finding could lead to cost-effective urine test

LOS ANGELES -- Elevated urinary leukotriene E4 levels (ULTE4) could prove to be an important biomarker for identifying aspirin intolerance in patients with asthma, according to findings from a systematic review and meta-analysis. The analysis of 10 studies in which the biomarker was analyzed in patients with asthma found UTLE4 to be an accurate marker for aspirin-intolerant asthma when measured using enzyme-linked immunosorbent assay, mass spectrometry, or radioimmunoassay. http://www.medpagetoday.com/MeetingCoverage/AAAAI/56604?xid=nl_mpt_DHE_2016-03-08&eun=g721819d0r
