Diagnostic Challenges of Borderline A2 Hemoglobin in β-Thalassemia Carriers: Insights from a Bangladeshi Cohort

2025-09-10

Abstract excerpt

<title>Abstract</title> <p>Background The identification of beta-thalassemia (β-thal) carriers during prenatal screening relies on elevated hemoglobin A2 (HbA2) levels. However, β-thal minor may present as silent carriers, showing no hematologic abnormalities despite carrying a mutation. Borderline HbA2 levels pose a diagnostic challenge. This study aimed to characterize 120 individuals—selected from a pool of 1,...
