Abstract
Hematologic testing informs management decisions made by clinicians managing critically ill patients. The technology underpinning such tests continuously evolves, so interpretation of results hinges on understanding the methodologies used and comparison to established standards. Hemoglobin concentration determination can be performed with point-of-care and noninvasive methods. These have varying agreement with laboratory-based methods. Patients treated with direct oral anticoagulants present a challenge as the action of these are not well differentiated using standard laboratory methods. Viscoelastic testing and some emerging tests may provide guidance for treating critically ill patients receiving direct oral anticoagulants.
