3 December 2025 (Wednesday) - NEQAS 2504 PA


I got hold of the results of NEQAS 2504 PA today…

2504 PA1

This was “the thin blood film from a patient of unspecified age and sex and with an unknown travel history. It showed a heavy (2.1%) infestation with Plasmodium knowlesi malaria”.  
I wrote “P falciparum - rings, trophozoites & shizonts 5% parasitaemia”. I got the species wrong and overestimated the parasitaemia, but I spotted malaria.

2504 PA2

The expert opinion said “There were no parasites to see on this thick film 
I wrote “Think it's negative. Saw one iffy thing

 
I’ll take that…

3 December 2025 (Wednesday) - Westgard QC Update

The nice people at Wesgard QC sent out their newsletter today. You can read it by clicking here. Much of it was rather dry; much of it went over my head. But one article gave me a wry smile.

Loads of stuff.

 

2 December 2025 (Tuesday) - Exchange Transfusions

There’s a phrase that is in common use – “exchange transfusion”. It implies that you take out all of someone’s blood because it is in some way sub-standard and exchange it for “decent” stuff. But you can’t just hoik it all out before putting in the good stuff as that would be fatal. Similarly putting the good stuff in one arm whilst taking out the bad from the other will lead to a degree of mixing.

Here’s an article examining the logistics of how it might best be done…

1 December 2025 (Monday) - BTLP-TACT Exercise

Last month I did thirteen BTLP-TACT cases, and still I’m getting emails about not doing enough… so here we go.
I was presented with one case – an eleven year old girl in ITU with burns needing two units of blood.
 
She grouped as A Rh(D) Positive with a negative antibody screen. I selected two units of A Rh(D) Positive K-Negative blood
 
I got the thumbs-up.
