My husband keeps telling me that this is something in his family that their normal blood is within this range. 
BTW he has G6pd
i remember we did a blood tests which was required by our country before we got married , they told us about G6PD but they didnt mention thalasemya 
and i have another question , whats the difference between carrier and trait ??
thank you
