My adult daughter was recently diagnosed with sickle cell trait.?

Question

Blood test shown that my daughter was diagnosed with sickle cell trait. I do not have the trait (at least I am not aware of, however I will be getting a test conducted soon) nor do her father and most importantly at Birth - blood was drawn from my daughter for the purpose of routine tests which I though sickle cell was part of. All test were fine (negative) for any disorder. My question is can and how is this be possible that she now have a trait of sickle cell?

Answer 1

my logical answer would be that they didnt test for it at birth. Usually it is not tested for unless there is a worry that it might be present. The trait is autosomal recessive meaning that you or her father might be a carrier and have no signs or symptoms.
