AFP levels elevated...2.68

mbd1816

I just got a call yesterday that my first screen test came back with an elevated AFP of 2.68 (not sure what that measurement really entails). I had to go back in for a second blood draw and screen. We wont know the results until sometime this coming week. I started looking online and cannot help but freak out about the potential for an open neural tube defect. ( I know there are other reasons you get an elevated result, but I still look at the worst case scenario).

Any idea what sort of scale this test is riding on... is 2.68 high or low or medium or what?
