•Utilization of a haemoglobin electrophoresis reader allows for fast and reliable identification•Swift quantification of various haemoglobin types including Hb A (normal), Hb S (sickle cell), Hb F (fetal), and Hb A2/C/E•Enables clinicians to discern relative concentrations of haemoglobin variants promptly•Facilitates comprehensive assessments crucial for precise diagnosis and tailored treatment strategies, particularly in hemoglobinopathies such as sickle cell disease. This evidence concerns the gene GSTM1 and sickle cell disease.
