Re: RA Latex Turbid- Test Results 257.5 IU/ML
Hi. I'm just a patient so please take what I say next with a BIG grain of salt. Because you mention hand & arm rashes, I also wonder if lupus is a possibility? Here are some thoughts & questions:
I've read that people with lupus can have a positive RF... but I don't know whether the "RA Latex Turbid" test you cited is ever positive in lupus (sorry). I hope someone who knows this test will comment more.
In addition to RA Latex Turbid, were you also tested for a whole slew of specific autoantibodies like anti-ds-DNA, anti-Sm, anti-Ro, anti-La, anti-RNP, antiphospholipid, etc.?
Some people can have symptoms of both lupus and RA. This is sometimes referred to as "rhupus".
Most, but not all, people with the systemic form of lupus do have a positive ANA. The exceptions are people with positive anti-Ro in whom ANA remains negative. These people can meet < 4, 4, or > 4 of the 11 lupus ACR criteria.
But it's mainly your comment about your rash that made me wonder about lupus. The two best-known lupus-specific rashes are malar (facial butterfly) and discoid (scarring), and both are included in the ACR criteria for diagnosing SLE. However---and this the part that surprises---there are perhaps a dozen *more* lupus-specific rashes not cited in the criteria. So anyone who has one of those *other* lupus rashes may find that doctors don't recognize them. That's what happened to me: I had one called Subacute Cutaneous Lupus Erythematosus (SCLE), the annular form; and I saw 8 local dermatologists before finally heading to a teaching hospital where I got answers quickly.
You could find the ACR criteria for diagnosing SLE on the lupus board---also other "sticky posts" (permanent info posts), including one about skin problems in lupus. If something there rings bells with you, I hope you'llpost more there or here.
And if you want to describe your rash in more detail, that might get more feedback, too. For example, is it photosensitive? On what part of arms & hands does it appear? (Mine favored outer part of upper arms and my back; those locations fooled my local dermies.) What does it look like? Does it itch, hurt, burn, etc.? Does it scar or depgiment? How long does it last (meaning does it come & go)?
As for symptoms, I had the ones you listed, plus GI misery and bladder misery, and migraines.
Anyway, I'm glad you found us & hope that you post again soon. With warm wishes, sincerely, Vee
