I
finally got round to tracking down the consensus results of the most recent
morphology NEQAS exercise…

said:
Large platelets
But
to be honest I was scratching about to say anything…

Consensus:
Rouleaux,
Microcytes, Ovalocytes

“This blood film was
from an apparently healthy 80-year-old woman who was undergoing routine
pre-assessment before unspecified elective surgery. All of her numerical
automated full blood count parameters were within ‘normal’ reference limits, as
were a biochemical screen including basic renal and liver function tests, and a
(perhaps unnecessary) coagulation screen.
This was an exercise in
where to ‘draw the
line’ between commenting on a feature, or accepting it as within normal limits”
I
think I got that right…

Don’t know

Consensus:
Polychromasia
tear-drop cells
Toxic granulation
Macrocytosis
Rouleaux

“Polychromatic cells and ‘tear-drop’
poikilocytes were by far the most commonly reported abnormalities. Well done to
all those who correctly observed the minor macrocytosis. I am always jealous of
colleagues who can reliably estimate red cell size from blood film appearances.
I struggle to do this reproducibly, other than by inference when other features
of conditions associated with either microcytosis or macrocytosis are present”
“The film came from the blood of a
40-year-old woman who was under occasional long term haematological follow-up,
with a given diagnosis of Diamond-Blackfan anaemia (DBA) made in childhood, but
now evidently in a long-term spontaneous ‘partial remission’”
I
think I did OK on these…
