INR testing - getting enough blood

Getting enough blood is somethhing that confounds beginners and experienced INR self testers alike; and while the manual shows a few things like this:

This is an important topic because if you don't get enough blood the machine will give an error and you've just wasted a strip. This can be more than a nusiance if

• you are on a low income (and $6 makes a difference in your part of the world)
• you were on your last strip and are waiting for the next delivery (never wait till you run out my freend, that's what preparation is all about)

I've noticed that people still seem to struggle. To help address this, I've done a previous video on the topic of "getting enough blood" over on this post. There you'll find this video:

This video is pretty quick and was intended to show some of the basic techniques (and inadvertently nicely show a source of mild panic as I forgot to cock the lance).

Later in discussion with someone I was assisting I did this more extensive video:

which goes into a lot more depth. 

That was about six months back and so I thought that (since I recently referred someone else to it yesterday) I thought I'd add it to my INR series here on my blog.

Remember; its important to use the right lance too.
