PANDAS 101 question

[Hrosenkrantz]

I have a friend who is investigating whether her kid has PANDAS. The kid's strep ASO is in normal range (like two digits) and has gone down with time. But the anti dnas b strep antibodies are high, in the 300s, and have gone up with time.

Why is that? If anti dnase b means there was an infection at one time, why would the level go up?

you may not like this answer. many blood tests are not precise and therefore numbers are not exact.

Remember too, that there is PANS. My DD has never had strep, but has PANS. It was triggered by a virus 2 years ago.
