Band 41 is the only band that showed up on my Labcorp test until after I had a full year of abx! But, Bands 18 & 41 (whether in IgM or IgG) are indicative of the tail of the bacteria, which can cross react with other Spirochetal bacteria such as Relapsing Fever, Pintas and Yaws, and Syphilis. There are several scientific articles showing this, which is why it's not consider Lyme specific.
I too had narcolepsy and GI dysfunction from Lyme and company.
I would encourage you to get more testing done, unless you are willing to start treatment based on a clinical diagnosis. Even the CDC says: "Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks. Laboratory testing is helpful if used correctly and performed with validated methods. "

If you haven't yet, it would be helpful for you to start with reading through the thread at the top of the forum titled,"New to Lyme?...Start here!!", as it is packed full of important information, symptom lists, helpful links and pdf's, how to detox when one has these infections, information on probiotics and much more. And this is another good list of possible detoxing routines:
