Properties and Units in the Clinical Laboratory Sciences

Area of Science:

• Clinical chemistry
• Environmental toxicology
• Human toxicology

Background:

• Current toxicant nomenclature lacks standardization, causing communication difficulties between clinical chemists, medical practitioners, and toxicologists.
• Inconsistent naming of toxicants (e.g., INN, trade names) hinders accurate data transmission and collation from various sources.
• A unified system is needed for presenting results of laboratory investigations involving toxicants in biological and environmental samples.

Purpose of the Study:

• To introduce a standardized concept of 'property' for presenting toxicological data.
• To establish a common communication base between different scientific and medical disciplines.
• To facilitate unambiguous interpretation of toxicological data for risk assessment.

Main Methods:

• Adherence to International Federation of Clinical Chemistry (IFCC) and International Union of Pure and Applied Chemistry (IUPAC) systematic terminological rules.
• Development of a list of properties for human and environmental systems involving toxicants.
• Recommendation of systematic terms with a unique code (NPU) for each property.

Main Results:

• A systematic terminology for toxicant properties has been developed based on IFCC-IUPAC guidelines.
• A list of properties for human and environmental systems involving toxicants is provided.
• A coding system (NPU) is introduced to facilitate unambiguous data identification and interpretation.

Conclusions:

• The proposed property concept and NPU coding system enhance communication and data interpretation in clinical and environmental toxicology.
• Standardized terminology improves the transmission and collation of toxicological data across disciplines.
• This framework supports accurate risk assessment and interdisciplinary collaboration in toxicology.
