Another BTLP-TACT
exercise… I was presented with one case – a nineteen-year-old lady in the
outpatient department needing two units of irradiated blood for the following
morning.
Her ABO
group was indeterminate. Does that invalidate the Rh(D) group? Her Rh(D) group
was negative as the control was also negative. So I said it was negative. Because
it was. If a new finding the whole lot would go off to NHSBT, and if a known
patient we’d know what was going on. Wouldn’t we?
Anyway…
The antibody
screen was positive in cells 1 & 2 so I performed antibody panels. The IAT
and enzyme panels were positive in cells 1, 2 and 3 which corresponded with
anti-D but didn’t rule out anti-Cw.
I
selected two units of irradiated O Rh(D) Negative blood which were K-Negative
I got the
green light…
