Background:

The development of human immunodeficiency virus type 1 (HIV-1) screening assays since 1985 necessitates reliable reference materials.
A global need exists for well-characterized HIV-1 reference sera to ensure consistent testing outcomes worldwide.

Purpose of the Study:

To review the ongoing efforts by major health organizations to prepare standardized HIV-1 reference sera.
To assess the serologic characteristics of the developing reference sera.

Main Methods:

Review of programs by the World Health Organization, Pan American Health Organization, and National Committee for Clinical Laboratory Standards.
Analysis of the types of sera being prepared: negative, HIV-1 seropositive, early seroconverter, and late acquired immunodeficiency syndrome samples.

Main Results:

Multiple organizations are actively engaged in the preparation of essential HIV-1 reference sera.
Both negative and HIV-1 seropositive sera are being produced by all participating organizations.
Specialized samples, including early seroconverter and late AIDS specimens, are also in development.

Conclusions:

Collaborative efforts are underway to establish critical reference standards for HIV-1 testing.
The availability of these characterized sera will significantly contribute to global HIV-1 diagnostic uniformity.
