In the book Lucifer's Hammer, the technique is explained.

Short version

A drop of your blood in a small amount of saline, a drop of someone elses blood in the same saline.

Shake it a bit.

Put it under a microscope, if it's not clumped you two can donate to each other.

Note that on a 3x5 card for each of you.

You have to xreference everyone to everyone to make sure. Lots of work ahead of time but saves time in a SHTF emergency.

Not true "in the field" type of medicine but you get the idea.
