doseringsprecision

Doseringsprecision, or dosing precision, refers to the degree to which a dosing system delivers doses that are consistent with each other and with the intended target. In a dosing context, precision describes repeatability: if the same dose is delivered multiple times under the same conditions, the results cluster closely together. This is distinct from accuracy, which describes how close the delivered dose is to the true intended amount.

In medicine and pharmacology, high dosing precision is important to ensure therapeutic effect and minimize risks. It applies to oral syringes, infusion pumps, metered-dose inhalers, transdermal patches, and laboratory pipettes, as well as to pharmaceutical manufacturing where active ingredients are dosed during formulation or filling. Poor precision can lead to dose variability, undermining efficacy or increasing adverse events, especially in narrow therapeutic index drugs or pediatric care.

Factors affecting dosing precision include device design and condition, calibration, and maintenance; fluid properties such as viscosity and temperature; operator technique and fatigue; and environmental conditions. In manufacturing and quality control, precision is assessed using repeated dispensations and metrics such as the coefficient of variation, along with gravimetric or volumetric verification and traceability to reference standards.

Methods to improve dosing precision include regular calibration and validation of equipment, standardized operating procedures, staff training, and the use of automated or closed-loop dosing technologies. Real-time monitoring and feedback can reduce variability, while appropriate dose rounding and preparation practices minimize human error.

Dosing precision intersects with broader concepts of dose accuracy, pharmacokinetics, and pharmacodynamics, informing dosing regimens, safety margins, and quality assurance in healthcare and pharmaceutical settings.
