I thought I would simply drop a spot of blood onto a test strip - how wrong I was! Inside the box was the test strip which looked like a VERY cheap pregancy test (like the kind from a pound shop). There was also a little device for puncturing your finger tip - this was effective, but had to be done right first time as it only worked the once. There were also 2 little plastic containers, one of which contains some solution and one of which contains a tiny slither of a glass tube - not much thicker than a few strands of hair - and so very difficult to see and get out of the bigger, plastic tube.
So what you do is get all the contents out. The test strip is wrapped in foil, so you might want to unwrap that first. Oh and you might want to check you can get your slither of glass out of the plastic tube easily too, and that you can get to your plastic tube of solution easily.
So, having done all that, you press the trigger on the orange plastic device that punctures your fingertip. It does hurt a little. So you now have a droplet of blood coming from a finger tip (so that hand is now immobilised for now so you don't "lose" the blood). This blood will stop quickly, so hurry up! With the free hand, you have to get the tiny slither of glass and hold it HORIZONALLY into the droplet of blood. My first tiny bit of blood went in fairly quickly and I thought, "This is easy". But then I could not get any more to go in. Half an hour later, my finger was almost bruised from squeezing the blood out, but still the glass tube wasn't filled to the end. But the glass vial MUST be filled to give an accurate result...
Stuff it, I gave up trying to fill it and popped it into the solution tube and shook it around. Fine. But lots of bubbles. Bubbles not going down. Was then supposed to stick in test stick (to test line limit, avoiding foam). Impossible to avoid the foam.
Anyhow, the test strip showed a control line as working. After a while, the strip gave a negative result, but I'm still wondering - is this an accurate result (because I didn't manage to get enough blood)?
So, 20 quid lighter and I'm none-the-wiser! Perhaps other people might have more success, but I found this - as a home test - badly designed and too difficult.
