10 September 2026 (Thursday) - BTLP-TACT Exercise

Time for another BTLP-TACT exercise. I had one case – a seventy year old woman needing six units of blood for an aortic aneurysm.
 

Her ABO group was indeterminate, but her Rh(D) group was negative.

The antibody screen was negative.

I selected six units of O Rh(D) Negative.

 
I got it right.

7 September 2026 (Monday) - NEQAS 2603 PA

I got the results of NEQAS 2603 PA today…
 
2603PA1
 
I saw some things that made me look twice, but nothing convincing. It was probably debris; certainly wasn’t a parasite.I don’t like thick films at the best of times.
The slide was actually negative and that’s what I said.
 
2603PA2
 
I saw some small worm-things. Was it  Leishmania donovani?
The expert opinion was that this was amastigotes of Leishmania. Bearing in mind I’ve never seen this outside of a NEQAS exercise I think I’m justified in saying “Go me” (!)

 

7 September 2026 (Monday) - BTLP-TACT Exercise

 

Time for a BTLP-TACT exercise… I was presented with one case – a thirty-two year-old chap in the haematology clinic with sickle cell disease needing eight units of blood for an exchange transfusion.
He grouped as O Rh(D) Positive with a negative antibody screen. I selected all the HbS negative units there were (four).
I got it right…   In reality that would be a resounding fail because I only came up with half the amount of blood needed. In reality I would get onto NHSBT and have them send some suitable blood. But this isn’t reality. It’s a simulator. Not a bad one, but quite obviously a work in progress on which no progress is being made. (That’s very ungrateful of me, isn’t it?)

6 September 2026 (Sunday) - CML


Well… it looks like CML to me. There’s nothing else that gives you quite such an assortment of myeloid cells.

4 September 2026 (Friday) - BTLP-TACT Exercise

Time for a BTLP-TACT exercise… I was presented with one case – a fifty-five year old chap in theatre needing six units of blood for gunshot wounds.
He grouped as O Rh(D) Positive with a negative antibody screen.
I selected six units of O Rh(D) Positive K Negative blood.
 
I got the thumbs-up.

2 September 2026 (Wednesday) - Fritsma Factor Update

The Fritsma Factor newsletter appeared in my in-box today. As always there was a lot to take in, but as a source of haemostasis-related CPD it can’t be bettered.


2 September 2026 (Wednesday) - NEQAS 2605BF

I got the results of NEQAS 2605 BF today
 
For 2065BF1 said
 
Thrombocytosis
Target cells
NRBC
Bizarre red cells
HJB (?)
Echinocytes
Rbc Fragments
Lymphocytosis
 
I wondered if this was heat changes, it was a case of congenital dyserythropoietic anaemia from the haematology clinic.
 
For 2065BF2 I said
 
NRBC
Target cells
Botyroid neutroohils
Lymphocytosis
Polychromasia
?? Occasional sickle cells???
 
I wondered if this was a case of heat stroke, it was a case of homozygous sickle cell disease three days after being treated for malaria. Interestingly the botroid neutrophils weren’t spotted by most people.
 
How did I do? Well, as I said to a colleague, this was a load of bollox. I spotted all of the salient features. However someone known to have haematological diseases which are being treated *aren’t* going to turn up as random chance findings.
The organization of NEQAS blood films leaves a lot to be desired…
