Learn About Lupus: Did You Know?

Lyme Disease and Lupus

Did you know that Lupus antibodies can cross-react with the test for Lyme disease?

Well, I found this out personally, the hard way. Without going into all the details here (click here to read more of my scare), I was tested for Lyme disease and the first round of tests came back positive. I soon discovered that there is a battle going on in the world of Lyme disease between two worlds of infectious disease doctors. Each side has a vastly different opinion about how Lyme should be tested and diagnosed. My first physician was a Lyme disease specialist, an internist out of Sacramento who wanted to treat me for the disease right away, without repeating tests; the second physician was an infectious disease specialist who thought it would be best to repeat the tests. She said that sometimes, Lupus antibodies can cross-react with the tests for Borellia Burgdorferi, the bacteria responsible for Lyme disease.

Who knew about Lyme disease and Lupus cross-reactivity?

Sure enough, the second test came back negative. I didn’t have Lyme disease after all, despite the results from the first test.

When I researched this, I found some information, but for the most part, most non-doctors aren’t aware of this. There was a blurb from a 1997 FDA article (now archived) that indicated the cross-reactivity. The only recent page that I found about this came from the Government of Alberta-Alberta Health Services, dated June 2015. On page 2 of their report, Laboratory Testing for Lyme Disease in Alberta, a section of Table 1 reads:

“Cross reacting antibodies may cause false positive reactions in persons with … autoimmune diseases (e.g., systemic lupus erythematosus and rheumatoid arthritis.)”

So, I chose to trust the infectious disease doctor’s explanation of cross reactivity as well as my own knowledge of my symptoms and other blood tests that clearly point to Lupus.

I share this story just to highlight the fact that doctors aren’t perfect, and when it comes to starting treatment for any condition, not just Lyme, it’s best to get a second opinion. From there, you can make an informed decision about how to proceed.
