I went through a stage of having to test my blood sugars daily with that infernal fingerprick stab test – not nice; I had very sore fingertips!
So, I was pleased to see today that scientists are working on a new ‘tear’ test – where you use a tear drop instead of blood. Although, does that mean we will have to smack ourselves in the eye to produce a tear. or watch a sad film or something? The idea amuses me :).
Here’s the story for you
“TEAR TEST THAT TAKES AWAY PAIN”
Millions of diabetics could soon monitor their glucose levels from a tear drop instead of having to endure painful daily blood tests. A new technique measures sugar levels in a tiny sample of fluid from the eye, to give a quick accurate reading. A soft foam tip is touched to the corner of the eye. It was invented by Dr Jeffrey La Belle at Arizona State Uni In Phoenix, US.
