The electrophoresis results will then show the types of hemoglobin present and the levels of each type. Normal types of hemoglobin are, for example: For adults, the reference percentages of normal hemoglobins are: The laboratory report must be evaluated by the specialist, that is, by the haematologist who will eventually prescribe a level II examination.
