"O k overall, all the testing regardless of what test we are doing has a really simple basic premise, and that is that we are looking for a particular shape of a virus or an antibody and that is unique. So that is called like a lock and key, so that means to say that this is a HIV virus or something. We will use in the test an antibody that will only fit to that. So it is a very pacific reaction. Now some of these reactions can visually see with the eye, others it is a chemical reaction. So what we have to do then is add what we call a reagent that tells you whether that happened or not it leaves a little tag and then depending on the test we will add a reagent that makes that a color. All that happened it gives you a color and then the instruments will then read that and the higher the yellow the more positive they are or not any color. And then the nucleic acid testing leaves a different color, so they use a kind of pink and a blue, so that regardless of what the test is, that is kind of the very basic underline premise of the test."
