Default Blood test for lupus? Anything else? - 09-25-2009, 06:18 AM

I had a blood test testing for lupus. Test paper said something about Erna's??? What other things will this test pick up or is it only lupus?

There is no finite blood test for Lupus.Blood tests only lead the doctor in a particular direction regarding Lupus

They do a full panel blood test. This includes your ANA(anti-nuclear antibodies), plat let count, and other stuff. If your ANA comes back positive then you have lupus. The full panel can tell you what other autoimmune diseases you have such as Sjorgen's disease, or Grave's disease.

The previous answers aren't accurate.

Here are the common blood tests for Lupus:

ANA (anti nuclear antibody test). The higher the titer the more likely the possibility that you have an AUTO IMMUNE disease, not necessarily Lupus. An ANA test is a NON SPECIFIC test and will be positive in about 5% of the population without an auto immune disease. The other 95% have some type of auto immune disease but not only Lupus. There are hundreds of possibilities.

DS-DNA (double strand DNA test) - If you test positive here there's a 95% chance that you have Lupus. However, many people with Lupus do not test positive for this test.

Anti-Ro, Anti-SM (smith) both blood tests that will help confirm a diagnosis but if negative you can still have the disease.

ASO- strep titer..to rule out strep virus and diseases like Rheumatic Fever.
