ReviewMetrology in medicine: from measurements to decision, with specific reference to anesthesia and intensive care.
Metrology is the science of measurements. Although of critical importance in medicine and especially in critical care, frequent confusion in terms and definitions impact either interphysician communications or understanding of manufacturers' and engineers' instructions and limitations when using devices. In this review, we first list the terms defined by the International Bureau of Weights and Measures regarding quantities and units, measurements, devices for measurement, properties of measuring devices, and measurement standards. The traditional tools for assessing the most important measurement quality criteria are also reviewed with clinical examples for diagnosis, alarm, and titration purposes, as well as for assessing the uncertainty of reference methods.

Fibrinogen Measurements in Plasma and Whole Blood: A Performance Evaluation Study of the Dry-Hematology System.
An accurate and rapid determination of fibrinogen level is important during hemorrhage to establish a timely hemostatic intervention. The accuracy of fibrinogen measurements may be affected by the specific methodology for its determination, fluid therapies, and anticoagulant agents. The dry-hematology method (DRIHEMATO®) is a novel approach to determine fibrinogen levels in plasma and whole blood based on thrombin-activated coagulation time. We hypothesized that plasma or whole blood fibrinogen level using the dry-hematology method would be similar to those measured with conventional plasma fibrinogen assays. ⋯ This study demonstrated that fibrinogen levels can be accurately assessed by the dry-hematology method in plasma and the results are not affected by heparin or colloids. For whole blood fibrinogen measurements by dry-hematology, hematocrit adjustment is necessary to compensate for dynamic changes in hematocrit in perioperative bleeding settings.
