Summary
A new control serum for HBsAg, anti-HCV, anti-HIV, and anti-Treponema pallidum testing was developed. Viral safety was ensured using three inactivation methods, maintaining serum stability for diagnostic reagents.
Area of Science:
- Clinical diagnostics
- Immunology
- Virology
Background:
- Control sera are vital for the accuracy of in-vitro diagnostic reagents.
- Ensuring viral safety is paramount when using human plasma-derived materials.
Purpose of the Study:
- To develop a stable control serum for HBsAg, anti-HCV, anti-HIV, and anti-Treponema pallidum testing.
- To ensure the viral safety of the control serum derived from human plasma.
Main Methods:
- Preparation of control serum from human plasma.
- Incorporation of three distinct viral inactivation methods.
- Validation of serum stability and characteristics post-inactivation.
Main Results:
- A stable control serum was successfully developed.
- The manufacturing process ensured viral safety.
- The control serum maintained its necessary characteristics for diagnostic use.
Conclusions:
- The developed control serum meets the requirements for HBsAg, anti-HCV, anti-HIV, and anti-Treponema pallidum testing.
- The implemented viral inactivation methods ensure a safe and stable product for clinical diagnostics.
