Considering the electrophoresis to be done at alkaline pH it is difficult to confirm this case as Sickle Cell trait.As because Hb D can comigrate along with HbS arriving at a diagnosis based on electrophoresis result might be erroneous.Considering an absolutely normal complete hemogram with lack of any symptoms I strongly suspect possibility of D trait(Hb D Los Angeles/Punjab etc).Hence I would like to perform an Isoelectric focusing.An HPLC could also be helpful.And ofcourse mutation analysis is confirmatory.
