Screening tests for cell-mediated immunodeficiency diseases

Area of Science:

• Immunology
• Clinical Laboratory Science

Background:

• Advances in immunology have led to revised understandings of immune deficiency disease etiology.
• Current immunological concepts necessitate reclassifying several disease entities.
• Clinical laboratories must offer sophisticated tests to align with ongoing immunology research.

Purpose of the Study:

• To review immunobiology and immune deficiency diseases.
• To provide in-depth coverage of specialized diagnostic tests available at major centers.
• To enhance laboratory scientists' ability to assist clinicians in diagnosis through understanding test principles and pitfalls.

Main Methods:

• Discussion of methods for lymphocyte separation, classification, and subclassification.
• Exploration of surface markers, rosetting techniques, and cellular responsiveness assays (mitogenic and antigenic).
• Review of lymphokine production assessment and future research tests like T-cell subset classification and antibody synthesis measurement.

Main Results:

• Detailed review of methods to categorize immune deficiency diseases based on lymphocyte analysis.
• Explanation of techniques including surface markers, rosetting, and functional assays.
• Overview of emerging research tests for T-cell subsets, lymphokines, and antibody synthesis.

Conclusions:

• Understanding specialized immunology tests is crucial for accurate diagnosis of immune deficiency diseases.
• Lymphocyte classification and functional assays are key to categorizing these diseases.
• Emerging research methods promise further advancements in clinical immunology diagnostics.
