Hi Tianna here from Third Age women's wellness. I wanted to go over an actual bone density scan just to give you an idea of what we're looking at and how they really determine these numbers. And I wanted to show this this is really kind of an explanation that my doctor had given me recently when we went over this together and I thought it was so great. I wish that he could do it. But he was a little camera shy, so I'm gonna go ahead and try. He used to be a radiologist.

And so he took these bone density scans and had to do the outlining of the bones on the scans to determine the bone density. So he was telling me that it's very it's not well, it just depends on who you're getting and who, who is doing the outlining and Each time they do it, if you don't have the same person, there's a little bit of error that could be had there. So I'll show you this, how he kind of explained to me. So the radiologist, actually the person that's drawing these lines is the radiologist, the person that's doing your scan. So they're outlining this. And you can imagine, you know, asking somebody to outline or trial to outline any kind of figure, and how much accuracy in that is there.

So, say that they had gone more into the black, then into the bony area, the more white space that would have changed dramatically what the ratings were. So now you see down here, there's a little area bone where they could have just outlined a little bit more of the bony area and that space but they didn't, they went inside of that bony area. Same thing down here. There's a little space right here where they could have gone out to this space and outlines that bony area, but instead, they didn't. So traveling down here, you're just getting the accuracy of whoever is outlining the space. And if they fall more into the bony space versus into the empty space, it's going to change dramatically what your bone density is going to come out to, because you'll see down here, so the area centimeter squared, so that's the area 12.54 centimeter square, is how much area they delineated in this space for L one, and then so on and so forth.

So 1432 for L two, and of course, down the line. So you're getting an average of that space. Sorry, an average of all of those spaces. So the T score. You'll see at the very bottom I'm here. The average of all of those is negative point eight, which, of course puts this person into the non osteoporotic.

But you'll see at each level, you can read, that will negative 1.1 isn't terribly into an austere product, but it is a little bit into that osteo product rehearse to a peanut green, excuse me. So just an idea of giving you to give you that that's an average there at the bottom, that big number that they give us an average of all the spaces. So it's good idea to look at each level. And then of course, just to recognize that there is a level of error in the measurements here, depending on who is outlining it, how well they outlined it. And then each time you get tested, how well that next person outlines that and how close they were to the last person. So You got tested, you know, four years ago, and now you're getting tested again, you probably have a different measure tester.

And so there's a bit of error there between testers and their ability to outline the very same pattern that the previous person did. So if your levels are off, you know, just maybe one or two percentage, then it might just be an error in how they outlined it. So, I'm showing this so that you don't get so scared as you go from, you know, test to test that there's a little bit of a difference. If it's a drastic difference, then we know there's a big change. But if it's a little bit of a difference, you know, maybe it goes from, you know, 2.5 to 2.6, or negative 2.5 to negative 2.6. Then we know, you know, maybe there could be an error in it, you know, if it was jumping from negative 2.5 to negative 3.5.

Yes, we know there's probably some element of A bigger change in there. So, anyhow, I just wanted to show this and hopefully give you some clarity and a little bit of understanding about the error that can happen when they're actually doing these tests.
