International standardization of gene amplification technology

Area of Science:

• Virology
• Molecular Biology
• Public Health

Background:

• The World Health Organization (WHO) established the international Working Group on the standardization of Gene Amplification Techniques for the Virological Safety Testing of Blood and Blood Products (SoGAT) in 1995.
• SoGAT serves as a unique international forum for scientific exchange on gene amplification technologies for blood product safety.
• The group focuses on technology evaluation and organizing collaborative studies for reference materials and standards.

Purpose of the Study:

• To standardize gene amplification techniques for virological safety testing of blood products.
• To develop and evaluate reference materials and working standards for viral detection.
• To facilitate international collaboration in virological testing standardization.

Main Methods:

• International collaborative studies for the development and evaluation of reference materials.
• Exchange of information on scientific aspects of gene amplification technology.
• Evaluation of gene amplification technology for product testing.

Main Results:

• Materials for hepatitis C virus (HCV) gene amplification are in widespread use.
• A collaborative study for an HCV RNA International Standard is progressing.
• Studies are underway to standardize technology for other viruses.

Conclusions:

• The SoGAT group is crucial for advancing the standardization of gene amplification techniques in blood product safety.
• International collaboration is key to establishing reliable viral detection standards.
• Ongoing efforts aim to ensure the safety of blood and blood products through standardized testing.
