A New Method for Screening Thalassemia Patients Using Mid-Infrared Spectroscopy

Area of Science:

• Biochemistry
• Medical Diagnostics
• Spectroscopy

Background:

• Thalassemia is an inherited blood disorder affecting hemoglobin production, leading to anemia.
• It is classified into alpha (α) and beta (β) types based on affected globin genes.
• Current diagnostic methods can be invasive or require chemical reagents.

Purpose of the Study:

• To evaluate Infrared (IR) Microspectroscopy as a novel diagnostic tool for thalassemia.
• To assess the ability of IR Microspectroscopy to distinguish between normal, carrier, and thalassemia patient samples.
• To explore the potential of IR-based spectral analysis in clinical screening.

Main Methods:

• Analysis of hemoglobin lysate from 333 individuals (normal, carriers, thalassemia patients).
• Utilized IR Microspectroscopy combined with Principal Component Analysis (PCA) and Partial Least Squares Discriminant Analysis (PLS-DA).
• Investigated spectral features correlating with different disease statuses and genotypes.

Main Results:

• Significant spectral differences were observed between the groups.
• Classification models achieved high diagnostic performance, with ~80-90% sensitivity and specificity.
• The non-destructive, reagent-free nature of IR Microspectroscopy offers advantages over conventional assays.

Conclusions:

• IR-based spectral analysis demonstrates potential as a complementary tool for thalassemia screening.
• Further integration with machine learning could enhance early detection and risk stratification.
• This approach may improve routine clinical workflows for thalassemia management.
