Her phenotype is C-E-, K-, M+N+S-s-, Le(a-b+), Jk(a+b-), Fy(a-b-). We assume c+e+. She has only formed the Anti-U. For a typical SCD patient with this phenotype we would give blood that is C-E-K- and sickle negative. She had her 6th exchange for the year last month. She usually has a 6 unit exchange, most of which come through the Rare Donor Program. Luckily we tend to get 2-3 weeks notice of the procedure.
