    A novel V-bottom microtiter tray method offers enhanced sensitivity for red blood cell typing. This technique improves upon traditional methods for agglutination tests, including direct, antiglobulin, and mixed field agglutination.

    Area of Science:

    • Hematology
    • Immunology
    • Clinical Diagnostics

    Background:

    • Accurate red blood cell typing is crucial for safe blood transfusions.
    • Conventional methods like tube and slide agglutination have limitations in sensitivity.
    • The need for more sensitive and versatile blood typing techniques is ongoing.

    Purpose of the Study:

    • To introduce a simplified and highly sensitive method for red blood cell typing.
    • To demonstrate the applicability of the V-bottom microtiter tray technique for various agglutination assays.

    Main Methods:

    • Utilized V-bottom microtiter trays for red blood cell typing.
    • Employed 0.2% cell suspensions for enhanced sensitivity.
    • Applied the technique to direct agglutination, antiglobulin tests, and mixed field agglutination.

    Main Results:

    • The V-bottom microtiter tray technique demonstrated significantly higher sensitivity compared to tube and slide methods.
    • The method proved effective for direct agglutination, antiglobulin testing, and mixed field agglutination.
    • The technique offers a simple and efficient approach to red blood cell serology.

    Conclusions:

    • The V-bottom microtiter tray method is a superior alternative for red blood cell typing due to its increased sensitivity.
    • This technique provides a versatile platform for multiple blood grouping assays.
    • The simplicity and sensitivity of this method can enhance transfusion safety and laboratory efficiency.
