Summary

Molecular methods, including DNA testing, are increasingly used for blood donor red cell antigen typing. This offers a feasible, cost-efficient alternative to traditional methods, improving red cell unit supply for patients.

Area of Science:

Transfusion Medicine
Molecular Diagnostics
Immunohaematology

Background:

Blood establishments increasingly use molecular methods for donor red cell antigen typing.
DNA testing is projected to play a significant future role in blood donor characterization.
Accurate antigen typing ensures efficient supply of red cell units for patients with irregular antibodies.

Purpose of the Study:

To evaluate molecular methods as a feasible alternative to standard serological assays for blood donor antigen typing.
To highlight the advantages of DNA testing in accessing a wide range of red cell antigens.
To discuss the implications of various molecular testing platforms for blood banking.

Main Methods:

Review of current practices in molecular typing of blood donors.
Comparison of DNA testing with traditional serological assays.
Assessment of different molecular testing platforms and their throughput capabilities.

Main Results:

Molecular methods, particularly DNA testing, are a viable alternative to serological assays for blood donor antigen typing.
DNA testing provides access to hundreds of antigens, independent of serological reagent availability.
Several molecular platforms offer medium- to high-throughput applications and can be more cost-efficient than serology.

Conclusions:

The adoption of molecular methods for blood donor antigen typing is a growing trend in blood establishments.
DNA testing presents significant advantages for blood banking, including broader antigen coverage and potential cost-effectiveness.
Further evaluation of molecular testing platforms is warranted to optimize their implementation in routine blood donor characterization.
