Preoperative screening for bleeding disorders : A comprehensive laboratory assessment of clinical practice

Essentials Patients with bleeding disorders are at risk of operative bleeding, but screening for these disorders is challenging. Patients with and without bleeding symptoms on a guideline‐based screening questionnaire were included and hemostatically phenotyped. The questionnaire could not differentiate between patients with and without hemostatic abnormalities. The discriminative power of the PT, aPTT, TT, Euglobulin lysis time, PFA, and the ISTH‐BAT was also limited.
