Hi Darius, welcome to the board
First of all, no Lyme test is completely reliable. Many people who have Lyme test negative. Although the CDC requires a large number of bands to show for the Western Blot to be positive, most Lyme doctors focus on which bands show. You are right that band 23 is specific for Lyme.
You need to be evaluated by a Lyme knowledgeable doctor. Besides Lyme, ticks can also transmit co-infections--Babesiosis, Ehrlichiosis (HME & HGE), Bartonella, and Mycoplasma. It is important to be tested for these because many people who have Lyme are co-infected.
Where do you live?
