Please help me in understanding

I am totally new to Lyme Disease and really need help in understanding this.

The symptoms I mentioned to doctor were numbness in hands, bit of arthritis in hands, difficult sleeping.   He ordered blood tests for vitamin levels and for Lyme Disease.  There was also a lump in my neck, which turned out to be Thyroid Cancer, which was surgically treated out of state two weeks ago.  When I returned home, the blood tests arrived.   It was a Western Blot done by Quest.   It came back all non-reactive except it was Reactive to B Burgdorferi 93 KD.   I tried to check here and there what it meant and found that it was highly specific to Lyme and likely chronic version.  So I am freaking out as I have many steps left to deal with the Thyroid cancer and now this Lyme concern on top of it.  I shall certainly check with doctor, but I doubt he will know that much, as the office had left a message that the test was negative.   I am not sure that is really the case if that crucial band came out positive.  Any and all help in interpreting this would be immensely appreciated.             

many of us get tested thru igenex since they have sensitive tests. any disease is given an open door by lyme beating down our immune system, so its still important to address lyme.
here are the meanings of each possible band
The following is a brief explanation of the test results.

Again, each band is an antigen complexed (bound together) with an antibody made by the immune system, specifically for that antigen (part) of Borrelia burgdorferi.

18: An outer surface protein.

22: Possibly a variant of outer surface protein C.

23-25: Outer surface protein C (osp C).

28: An outer surface protein.

30: Possibly a variant of outer surface protein A.

31: Outer surface protein A (osp A). 34: Outer surface protein B (osp .

37: Unknown, but it is in the medical literature that it is a borrelia-associated antibody. Other labs consider it significant.

39: Unknown what this antigen is, but based on research at the National Institute of Health (NIH), other Borrelia (such as Borrelia recurrentis that causes relapsing fever), do not even have the genetics to code for the 39 kDa antigen, much less produce it. It is the most specific antibody for borreliosis of all.

41: Flagella or tail. This is how Borrelia burgdorferi moves around, by moving the flagella. Many bacteria have flagella.

This is the most common borreliosis antibody.

45: Heat shock protein. This helps the bacteria survive fever. The only bacteria in the world that does not have heat shock proteins is Treponema pallidum, the cause of syphilis.

58: Heat shock protein.

66: Heat shock protein.

This is the second most common borrelia antibody.

73: Heat shock protein.

83: This is the DNA or genetic material of Borrelia burgdorferi. It is the same thing as the 93, based upon the medical literature. But laboratories vary in assigning significance to the 83 versus the 93.

93: The DNA or genetic material of Borrelia burgdorferi.
