I was hesitant about writing this post, because unless I
choose my words quite carefully I could risk leaving you with one or both of
two impressions: that I take the medical trauma I’ve been through this past
week or two less than seriously; or, worse, that have anything less than the
highest regard, respect and gratitude towards the many amazing NHS staff who
have been so brilliantly supportive and effective. Neither of those is the case. It’s not over yet, but it’s getting
better. And a big thank you to the NHS!
As part of my treatment, I’ve been put on a course of
Warfarin. As I’m sure you know, in
addition to killing off any rats that might be lurking in my bloodstream, this
reduces the rate at which blood clots, and hence the risk of recurrences of the
original problem. Frequent tests determine
how well the drug is doing this, by measuring something called the INR. Briefly, an INR of 1.0 is normal, 2.0 means
clotting takes twice as long, and so forth.
My target is 2.5.
So, you’ll be wondering, what does ‘INR’ stand for? Here’s where the fun starts. You won’t guess, so I’ll tell you. It stands for ‘International Normalized
Ratio’. (Also the Russian Institute for
Nuclear Research, McKinley National Park Airport and Indian Rupee, but let’s
stick to the point.) So if you want to
know how fast your blood is clotting, just have your international normalized
ratio checked, okay?
I’m not totally against jargon – it can be a useful form of
shorthand – but I do prefer that it bears at least a smidgeon of connection to
the concept it represents. The roots of
this particular item are lost in the mists of the early 1960s, the mystery
perhaps being how it’s persisted for so long in the face of its patent
meaninglessness. It’s not even a ratio,
for God’s sake! Couldn’t someone, over
the decades, have thought to give it a more helpful label? ‘BCR’ (Blood Clotting Rate), for
instance.
