When analyzing a chromatogram, the possibility of the existence of delta-thalassemia or an HbA2 variant should be considered, apart from alfa-, beta-thalassemia and structural haemoglobinopathies. To this end, each of the peaks and their percentages should be considered to allow for correct interpretation and to avoid misdiagnosis as much as possible.
