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.

Nothing vs. smth: First off, not sure why it was done. You must understand that in medicine it is not right to chase a positive test only. There may be symptoms also suggestive of a disease.

Typically a screen for lupus and related diseases, many older folks who are healthy run a low titer. ...Read more
Further testing: A positive ANA may not be significant. First of all why was the test done. If it was done for joint pain it will mean more then if a physiciab did one as a part of an annual physicial. Certainly, we are may be more concerned based on the value but also the pattern of the ana. The titer may mean an autoimmune disease is present based on the complaints, physical exam, and the values of other tests. ...Read more

Nothing: Lupus is diagnosed based on a combination of lab tests and symptoms. A lab test alone does not diagnose this disease and could be positive in many diseases as well as individuals who have no health problems. ...Read more
By itself, not much.: In a setting where a rheumatologic disease is likely, anachoice can confirm, or narrow down, the diagnosis, but it is so often positive in perfectly healthy people that it can't be used as a screening tool. ...Read more
Only a screening tst: Hi Jessica, A weakly reactive syphilis test or RPR test is a screening test. Syphilis and other things can cause this test to be positive. The definitive test is the FTA, or Flourescent Treponemal Antibody test. This is specific for Syphilis and if this is positive then you have the disease. ...Read more
