Standardizing plasma protein measurements worldwide: a challenging enterprise

Area of Science:

• Clinical Chemistry
• Laboratory Medicine
• Biotechnology

Background:

• Harmonizing laboratory results is critical for quantitative protein assays due to their clinical significance in disease monitoring.
• Specific protein measurements are vital for patient management and therapeutic efficacy.
• The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Scientific Division addresses this need through its Committee on Plasma Proteins.

Purpose of the Study:

• To report on the IFCC Committee on Plasma Proteins' efforts to achieve global comparability in plasma protein measurements.
• To detail the production of essential reference materials for plasma protein standardization.
• To highlight the methods employed in the manufacturing and characterization of these reference materials.

Main Methods:

• Production of plasma protein reference materials.
• Characterization of reference materials using established and validated procedures.
• Ensuring reproducibility of earlier standardization methods.

Main Results:

• Successful characterization of new reference materials, ERM-DA470k/IFCC and ERM-DA472/IFCC.
• Demonstrated reproducibility of established procedures for reference material production.
• Maintenance of standardization through consistent methodology.

Conclusions:

• Plasma protein reference materials significantly enhance the harmonization of patient protein results.
• Improved harmonization of laboratory data leads to more reliable disease monitoring.
• Standardization efforts ultimately contribute to better patient care and clinical decision-making.
