Beta thalassemia is a type of genetic disorder characterized by reduced beta chain synthesis hampering hemoglobin production. PCR assay uses targeted primers, which are amplified and used to identify mutant alleles. Healthcare professionals use the Molecular Diagnostics (MDx) Beta Thalassemia Polymerase Chain Reaction (PCR) test to diagnose and classify beta thalassemia, identify carriers, and facilitate genetic counselling and management.
