Red cell autoagglutination.
Caused by IgM autoantibodies occurring in autoimmune haemolytic anaemia or can
be secondary to viral infections.
Aggravated by relatively
cold temperatures, the best way to get a reliable blood count is to warm the
blood sample prior to analysis.
A very good way to
enhance the auto agglutination is to position the blood count analyser directly
below the air-con outlet whilst rudely pooh-poohing what you are being told,
and then pretending to be surprised when cold agglutinins becomes a serious
issue when you can’t get a sensible result no matter how much you warm the
sample….
Speaking totally
hypothetically of course…
