Eldon Card source

[DrBaboon]

I was thumbing through a catalog that came in this week's mail. Believe it or not - until I read about these in the book, I had previously not heard of an Eldon Card for blood typing. I'd always simply had it done through the hospital lab.

$6.65 each in the US.

I haven't seen those in years - it's good to know they're still around.

But, whats the shelf-life vs. the reagents? Accuracy (Sp/Sn)?
