aso and anti d-nase B

Recommended Posts

Hey Smarty --


Sort of answering more in the interest of bumping this up, more so than having a definitive answer. I'm not sure I have the timeframes accurate, so someone will surely be able to check me.


ASO, as I recall, rises immediately upon infection, so higher ASO is supposed to reflect strep exposure within the two weeks or so prior to the test.


AntiDnase-B are "latent titers" and indicate strep exposure something like 6 to 8 weeks (or potentially more) prior to the test.


I've read here repeatedly, and also had docs tell us, that it is not necessarily the level of the titers, but the direction in which they're moving.
