A group and save sample
came in shortly before the day staff went home this evening. The
diagnosis was "abdo pain" which is rather vague. The
outcome could be anything from the patient going home following a
good fart through to massive blood transfusions following extensive
surgery for a myriad of reasons. Such samples shouldn't really wait
around.
This one had a positive
antibody screen. The antibody identification panel showed anti-Fy(a)
by IAT technique and was negative by enzyme technique (as one
might expect for anti-Fy(a))
This was a known
antibody, there had been several previous encounters. therefore
referral to a specialist centre wasn't necessary on this occasion.
Blood wasn't requested on
this encounter; had it been required there shouldn't have been too
much trouble providing it. With about a third of the population being
Fy(a) negative and the patient being O Rh(D) Positive statistically
we would expect to have about seven to ten suitable units in the
blood bank.
Statistics
notwithstanding I had a rummage in the blood bank just to be sure we
could provide something in an emergency.
We could...

are always good in a little case study:

Hi, I stumbled across your blog (which I really enjoyed!) whilst researching some help for the IBMS Specalist Portfolio. I can see you've provided some questions and wondered if these are for public use and if I could incorporate them in to my work? I also have some other questions (if you don't mind) and I couldn't find any way of contacting you expect via comments! I can provide you with my email if you have time for some queries. Thank you :) Nic
