Key result
Specific laboratory assays like dilute thrombin time and anti-Xa assays can accurately measure DOAC levels, though availability varies and a universal assay is urgently needed.
Why the study?
Although DOACs do not routinely require monitoring, measuring actual concentration or drug presence is increasingly important in scenarios such as major bleeding, urgent surgery, extremes of body weight, or failed therapy.
What laboratory tests are available to guide the monitoring of direct oral anticoagulants in specific clinical scenarios?
What laboratory tests are available to guide the monitoring of direct oral anticoagulants in specific clinical scenarios?
Specific assays like dilute thrombin time and calibrated anti-Xa assays are needed for accurate DOAC measurement in critical clinical scenarios, though availability remains a challenge.

DOAC level testing may aid urgent decisions in bleeding or surgery; leaves open optimal assay selection and thresholds.
Ravi Sarode (2019) conducted a review in Thromboembolism / DOAC monitoring. Direct oral anticoagulant laboratory monitoring was evaluated. Specific laboratory assays like dilute thrombin time and anti-Xa assays can accurately measure DOAC levels, though availability varies and a universal assay is urgently needed.
