an ANA is basically an anti-nuclear antibody.
What that means, is that it's a test to see if your body has made antibodies against itself. Antibodies are what your body makes to fend off harmful viruses, but sometimes, like with Lupus, something goes wrong, and the body begins to attack itself. The ANA is basically a test to see if your body is attacking itself, and if so, how bad it is.
The ANA should have a number separated by : and another number. For example, my ana is 1:80. That's a very low ANA, and may or may not be indicative of a problem. The first number should almost always be 1, and the second number means how many times they can dilute your blood and still tell the results.
So a higher ANA would be something like 1:320, or etc.
Now, I'm not sure what she means by mono testing, or whatnot. The good news is that she is taking tests and finding some things that could be flags for certain things, so she's ruling things out by doing this.
I understand about wanting a diagnosis, hehe. I only just got diagnosed yesterday, and i'm not used to knowing what's wrong with me yet!
anyways, I hope that helped even a little, fingers crossed that you get a diagnosis soon
One day at a time, one breath at a time... We can get through this.
