Kalani R, Liotta EM, Prabhakaran S. Diagnostic Yield of Universal Urine Toxicology Screening in an Unselected Cohort of Stroke Patients. PloS one. 10(10). e0144772. PMID: 26675665 [PubMed] PMCID: PMC4686022
Illicit drug use increases the risk of cerebrovascular events by a variety of mechanisms. A recent report suggested that universal urine toxicology (UTox) screening of patients with stroke may be warranted. We aimed to evaluate the diagnostic yield of urine drug screening among unselected patients admitted with acute stroke or transient ischemic attack (TIA).
