I don't recall ever being screened for any of the anemias. One of my late cousins was anemic. It was the cause of his death (couldn't get an ambulance and blood transfusion in time). If it is genetic perhaps there is a chance I am a carrier??? Anyway the yellow urine didn't last too long if my memory serves me well (week or two at most) and I have been relatively healthy since then (touch wood). As I result of having had yellow jaundice I was told I could never donate blood.
