The ANA is calculated in "titers". So the next number from 1:320 is 1:640. There are no results between 1:320 and 1:640. If it were higher than yours, the next result would be 1:1280.
When they test for ANA, the sample is diluted and tested. If they find anti-nuclear antibodies in the diluted sample, they dilute it again, if there is still detectable anti-bodies, the number is doubled each time it is detectable. They continue to dilute and test until they get a diluted sample with no detectable ANA. Clear as mud?
Hopefully you'll get some kind of treatment plan when you go back to see the doc. But likely, he'll want more bloodwork. :( But, you are on your way to receiving some help, ok?
