    Area of Science:

    • Immunology
    • Clinical Chemistry
    • Rheumatology

    Background:

    • Total haemolytic complement measurement is crucial for diagnosing rheumatic diseases.
    • Existing methods, like Kabat and Mayer's, can be complex to perform.

    Purpose of the Study:

    • To describe a simpler method for measuring total haemolytic complement.
    • To propose a new unit for complement activity measurement.
    • To suggest improvements for assay standardization.

    Main Methods:

    • Development of a simplified assay for total haemolytic complement.
    • Introduction of a novel unit based on normal serum complement activity.
    • Comparison with established methods (e.g., Kabat and Mayer).

    Main Results:

    • The described method is easier to perform than previous techniques.
    • A new unit is proposed, offering a potential replacement for CH50 units.
    • Recommendations for enhancing assay standardization are provided.

    Conclusions:

    • The simplified total haemolytic complement assay offers diagnostic value in rheumatic diseases.
    • The proposed unit and standardization steps can improve assay reliability and clinical application.
    • This work facilitates more accessible complement activity assessment in rheumatology.
