What does false positive diagnos on lupus mean?

What does false positive diagnos on lupus mean?

ANA positive: I see two to three patients per week that have a positive antinuclear antibody (ANA) but do not have lupus. The ANA blood test is very sensitive meaning that if you have lupus, the blood test comes back positive. However, it is not specific meaning that if the ANA is positive, you may or may not have lupus as there are over thirty causes of a positive ana. Normal people can have a positive ana. ...Read more

If i tested positive for lupus a few yrs ago and now tested 2x positive HSV II but never had sigms of it, could it be false due to autoimmume?

If i tested positive for lupus a few yrs ago and now tested 2x positive HSV II but never had sigms of it, could it be false due to autoimmume?

Unlikely false pos: The pain along the strip of skin is more suggestive of an infection rather an autoimmune cause like lupus. With hsv ii, many people think of the presence of a sore, blister or ulcer on the skin; depending on details of the case and the specific test results, symptoms may be absent or the lesion is not in an easily observable site on the skin. Definite discuss your good question with your doctor. ...Read more

I recently had a positive ANA test. My dr tested folupus but it was negative. I have all the symptoms except rash. Can u have a false neg lupus test?

I recently had a positive ANA test. My dr tested folupus but it was negative. I have all the symptoms except rash. Can u have a false neg lupus test?

Keep working: Lupus is defined by a series of criteria, of which a strongly positive ANA is one. No specific test turning out negative rules out lupus. Perhaps you were tested for anti-smith(sm), which if positive hands us the diagnosis but is only positive in 1 of 3 patients. Perhaps there is a misunderstanding or you can request consultation. Lupus requires great courage -- will be thinking of you. ...Read more

Maybe,maybe not: The initial screening tests they do for syphilis and many other issues are lower cost tools (few bucks)to find the subgroup of large populations (pregnant ladies) that need the more expensive (lots of bucks) confirmatory test . There are many things that can cause a false positive.The next step would be the confirmatory test that should give you the answer. ...Read more

My wife has endometriosis and systemic lupus, we took 2 (cheap) pregnancy tests and they both turned out positive. Can lupus or endo cause a false pos?

No.: False positive urine pregnancy tests are rather rare. Some possible causes are operator error, a biochemical pregnancy, or interference with the assay from recent infertility therapy. SLE and endometriosis should not impact the specificity of a urine pregnancy test. ...Read more
