With a few
minutes spare I thought I might have a go at a BTLP-TACT exercise before
setting off to the late shift…
I was
presented with two cases:
91546 – a thirty-one-year-old chap in the operating theatre needing two
units of blood within the next two hours for an above-knee amputation
He grouped
as O Rh(D) Negative with a negative antibody screen
I selected
two units of O Rh(D) Negative blood
88251 – an eighty-four-year-old woman requiring a pre-operative group
& save.
She
grouped as… well… I don’t know what the software expected. The ABO group was
indeterminate. The D group was negative.. the control worked. But what is the
control in this case supposed to control?
I called
the group ”Indeterminate Rh(D) Negative”.
To add
insult to injury the antibody screen was positive in cells 1 and 2, so I
selected identification panels.
The IAT and
enzyme panels were positive in cells 1, 2, 3 and 4 which corresponded with anti-C
and anti-D but could not exclude anti-Cw.
I amazed
myself by getting the green light, and headed off to work feeling flushed with
success.
