29 July 2022 (Friday) - BTLP-TACT Exercise

Time for another BTLP-TACT exercise. I was presented with one case – a twenty-six-year-old chap with a GI bleed needing four units of blood within two hours.

He grouped as O Rh(D) Positive, but a rather weak Rh(D) Positive.
Should I have called it indeterminate? No. It was positive; just weak. The antibody screen was negative.

I took no chances and selected four units of O Rh(D) Negative (K-negative) blood and pressed the “submit” button expecting failure..

I got it right…

28 July 2022 (Thursday) - Highest Wbc Ever (?)

Here’s a photo of something I saw today. This is a shot of a film made from the blood of a patient with the highest white cell count  have ever seen in forty-one years of blood testing.

Wbc 842.0

It’s a case of CLL in a chap who is one hundred and three years old… smear cells, prolymphocytes...


27 July 2022 (Wednesday) - CD4 / CD8 ?

The nice people at Lablogatory sent an update on lymphocyte subsets today. A test which so many labs have tried to set up, and then realised that it is best sent to a specialist centre… A shame – it isn’t *that* difficult to set up.
