She's so young. They will likely do blood work for other clotting factors (homocystine, c protein, factor V leiden).

There is actually quite a few good sites about APS (I can give you links if you'd like) and I'd be happy to answer any questions as best I can.

It would be pointless to tell you not to worry, but I have never heard of someone being treated with blood thinners unless there is a confirmed thrombotic event, so maybe this was caught early enough to just keep a watchful eye and monitor.

Good luck and best wishes to her.
