The results of NEQAS 2502 PA became available today. It gas
to be said that I wasn’t overly confident on that survey.
2502 PA1 was a thick film. I said “Parasites
present”. There were – P. Knowlesi. The expert opinion said “It is optimistic to hope to distinguish
between different species of Plasmodium on a thick film unless you are working
in a high prevalence area or have extensive experience”.
For 2502 PA2 I said “ring forms” and there was.
The expert opinion said “This is an example of babesiosis, most likely due
to Babesia microti. It was a difficult film to interpret. B. microti is mainly
seen as small rings, so it is easily confused with Plasmodium sp”.
In both cases I spotted parasites present. Obscure
ones that I rarely, if ever (never), see in practice. But I spotted them.
Had this happened in reality the case would be referred to a specialist lab.
I’m taking this as a success
