33627 – a sixty-three year old woman in theatre requiring two units of blood within two hours.She grouped as A but with an indeterminate Rh group. BUT the positive control in the group made the entire group uninterpretable. I made this mistake in July, didn’t I?So I reported everything as uninterpretable.The antibody screen was positive in cells 1 and 2.The IAT panel was positive in cells 1, 2, 5, 8 and 9 which corresponded with anti-M but didn’t exclude anti-Cw or anti Lu(a).The enzyme panel was negative in everything which did exclude anti-CwAnti-Kp(a) was excluded by the screenI issued two units of O Rh(D) Negative which were M negative. They weren’t labelled as Lu(a), but that’s why we crossmatch.70760 – a fifty-six year old woman also in theatre requiring four units of blood tomorrow.She grouped as O Rh(D) Negative with a negative antibody screen.I selected four units of O Rh(D) Negative
