Re: Lupus markers
Hi, Sallie. There are three "sticky posts" (permanent info posts) at the top of the thread list. One contains the ACR criteria for classifying lupus, but these are pretty much used for Dx'ing it, too.
These criteria are varied because the disease itself is so varied. Meeting at least 4 of the 11 (not necessarily all at once) usually creates a Dx of systemic lupus (SLE). Anti-Sm antibody is considered a marker and fulfills one criteria; ditto with positive ANA, which is listed separately. Next, drs. would probably look closely for *other* specific symptoms, problems & test results from that same list.
Are you seeing a rheumatologist? They're the ones best versed in lupus.
The "something about blood clotting" you mention may be an antiphospholipid antibodies or anticardiolipin test. Both tests have to do with a clotting disorder called antiphospholipid syndrome (APS). It's seen "standalone" and also in conjunction with lupus. There's a separate "sticky post" on it, too.
Thorough rheumies take a *lifetime* medical history. FYI, there are actually many other things commonly seen in lupus that don't appear on the ACR list, only because they aren't as "diagnostic", if you know what I mean.
I hope your doctor(s) & you keep working at sorting things out. While I hope you don't have lupus &/or APS, if you DO turn out to have either, please know that many people can do pretty well, with the right help and regular follow-ups. So just hang in there, OK? I hope you keep posting here. Bye, with best wishes, Vee
