Here’s something to
make you think (well, it made me think). We had a case of anti-U the other week. Yesterday we had a case of anti
Mi(a). There’s obscure for you.
It turns out that the
frequency of the Mi(a) antigen is less than 0.1% among Caucasians, Negro
and Japanese people, but in South-East Asia, the frequency is different. In
Chinese blood donors in Hong Kong it is 6.28%, 88% in the Ami mountain people
of Taiwan and 9.6% in Malaysian blood donors.
Well… this isn’t news, it it? There has always been racial variations in the distribution of blood groups. But… I saw an advert on Facebook the other day advertising going half way round the world for cheap orthopaedic surgery. Whilst you may well be getting first-class treatment, you’ll also be getting blood from local donors (if transfused). And possibly getting anti-Mi(a) and potentially other antibodies to rare (in the UK) antigens which may be an issue. Do UK screening cells have the Mi(a) antigen and all the other obscure (in the UK) ones?
I don’t know…
