Exagen Lupus Test: Looks like somebody's hard work paid off!
Exagen Diagnostics, a rheumatology specialty laboratory, has developed a groundbreaking diagnostic test for lupus, and a fresh new study has found that it works. How exciting!

Because the symptoms of lupus mimic other rheumatic diseases, it has historically been difficult to arrive at a correct diagnosis. 51% of patients with suspected autoimmune or immune disorders are initially misdiagnosed.
Marketed as Avise CTD, the diagnostic tool has recently been proven in studies to be a significant improvement over traditional lab tests. It is the only validated lupus test available incorporating scientifically proven CB-CAPS technology, and it is having a big impact with doctors and their patients.
The test, which requires only one blood draw is helping physicians distinguish between overlapping symptoms and aid them in the differential diagnosis of several systemic autoimmune rheumatic diseases, including the difficult-to-diagnose lupus. It took the company and collaborators over five years to validate the test.
A study recently published in the on-line journal Lupus Science & Medicine proves its effectiveness. “The results showed that this test is highly specific for SLE,” he says, “approaching 100% in the differentiation of SLE versus primary fibromyalgia.”

At the above link, you can print out a one sheet explaining their test that you can then share with your doctor who can request the test. Might sound easier than it really is :), but it's worth a shot.
Here's the text from the website:
If you are ready to find out what the underlying reasons are for your symptoms then talk to your doctor about the Avise CTD diagnostic test. With over 90,000 tests performed, there are many doctors familiar with Avise CTD, however, you can open and print a physician communication letter below to help explain the test in greater detail in case your physician is not familiar with this novel service.

Also, I would contact your local lupus organization, and see if they have any resources for you.
1. The CLIFT (Crithidia luciliae) aspect does not specify which version it is. Its a very old test, with the weakest utility when combined with the ELISA. There are better cross-references to use, including the mCLIFT, which modifies the old test with a modified assay so that the subject text is more visually clear and contrasted. I looked for a patent for the test, but Avise does not list a number anywhere, and there is no mention that it is the improved CLIFT. The old version is about as a good as a coin flip.
2. It excludes the very important anti-C1q, which is a newer marker with decent association with forms of lupus. Its not conclusive, but its a good cross-reference, and it could help focus treatment more quickly.
Your doctor might be able to elaborate, too. Always important to loop them in! :)
Thanks again!
