"In conclusion, the DOAC Dipstick can test for the presence of DOACs in 90.9% of all patients with suspected acute stroke (ischaemic/haemorrhagic) or transient ischaemic attack early after hospital admission, providing routine clinical test results are unambiguous."

The DOAC Stroke Registry study evaluates whether rapid urine dipstick testing can safely and accurately identify stroke patients with low anticoagulant levels who would otherwise be ineligible for life-saving thrombolysis. By comparing this point-of-care tool to time-consuming laboratory assays in a real-world regional setting, the research aims to validate a faster diagnostic pathway. If successful, this approach could significantly expand treatment eligibility and improve clinical outcomes by providing timely, data-driven decisions for reperfusion or anticoagulation reversal.

"Urine-based DOAC dipstick testing is a rapid, accurate, and reliable method for detecting anticoagulatory activity in AIS patients, providing a valuable tool to guide acute therapeutic decisions. Future studies are warranted to validate its clinical impact and broader applicability, especially in the emergency setting."
