Product Description
The Biorex Diagnostics Anti-Lea reagent is a ready-to-use solution for the detection of the Lea antigen in the Lewis (LE) blood group system. It is intended for use in immunohaematology laboratories where accurate and reproducible antigen detection is essential for blood grouping, extended phenotyping, and transfusion compatibility testing.
The Lewis blood group system is distinct in that its antigens are not intrinsic to red blood cells but are adsorbed from plasma, which can result in variable expression. This variability makes reliable reagents critical for correct interpretation of serological results. The Anti-Lea reagent provides consistent performance, allowing laboratories to confidently identify Lea-positive and Lea-negative red cells in both routine and complex testing scenarios.
Supplied in a stable, ready-to-use liquid format, the reagent eliminates the need for dilution or preparation, reducing hands-on time and minimising the risk of handling errors. Its direct agglutination methodology produces clear, easily interpretable results, supporting efficient workflows in both manual and semi-automated testing environments. When used as part of a broader antigen testing panel, the Anti-Lea reagent contributes to accurate Lewis system phenotyping and effective antibody investigations.
Key Features
- Accurate Lea antigen detection – identifies Lea-positive and Lea-negative red cells
- Polyclonal reagent – provides broad specificity and reliable antigen detection
- Direct agglutination method – clear and interpretable results
- Ready-to-use format – eliminates dilution and reduces laboratory errors
- Supports complete Lewis system phenotyping – complements Anti-Leb reagents
Benefits
Use of the Anti-Lea reagent supports accurate blood grouping and extended phenotyping by enabling reliable identification of the Lea antigen. This is particularly important during antibody investigations, where Lewis antibodies may interfere with serological testing. Consistent reagent performance helps reduce discrepancies and supports confident interpretation of results.
The ready-to-use formulation improves laboratory efficiency by simplifying workflows and reducing preparation time, making the reagent suitable for routine testing as well as higher-complexity immunohaematology investigations. Its compatibility with standard serological techniques allows seamless integration into existing laboratory protocols.
The Anti-Lea reagent also supports safe transfusion practices by contributing to accurate donor and patient phenotyping. When used alongside Anti-Leb, it enables comprehensive Lewis system evaluation, supporting improved transfusion decision-making and enhanced patient care across blood banks, hospital laboratories, and reference immunohaematology facilities.
