I have decided to see what the rheumy I'm seeing found out with all my labs, then ask him if he will do the IgeneX test. If it's positive I will go to an LLMD in Denver. If he won't I'm not really sure what to do next. My husband is really bucking me on this thing. My insurance pays for my Rheumy but won't pay LLMD.
Will the ABx I'm on for my UTI affect the western blot???
I'm detoxing, but still have aching joints and a massive headache. Thinking of heading to the sauna tomorrow...
Surprised though, I usually get a rash when on ABx and haven't seen one.

Jessica, diagnosis: unsure

From what I understand, there is no way to judge if antibiotic will affect your blood work. I am on antibiotics for a year now. I tested 3 bands IGG (old infection) initially 5 years ago and now test 3 differnet bands IGM (recent or active infection) and both still a negative CDC. Do yourself a favor and get to an LLMD. Your insurance may pay part as an out of network dr. ? I had my primary draw my blood and shipped to Igenex myself when infectious disease dr. wouldn't do it. My insurance reimbursed me partly. I had a massive headache for 4 straight years and a few months of antibiotics made all the difference. I have a huge way to go with neurological problems, but a trip to an LLMD and getting the RIGHT antibiotic now instead of later may get rid of your headache and avoid the additional symptoms I am now facing.

When I started investigating Lyme and blood tests, etc, I took note that they (Igenix? I don't remember) said to take the test after you have been off Abx for so many weeks.

However, also during my research, I learned that while too many tests are false negatives, often times they will become positive after the patient has been on abx for about 4-6 weeks.

Reason being, that too often, with a long term infection, the body is finally out of antibodies, or has become so depleted of them that it will not show on a test. So, once a patient has been on abx for awhile, the antibodies are strengthened and will then show up on a lab test.

Sooooooooo..... THIS is the reason that each band must be read and the significance of each band must be noted.  My understanding is that even after some time on abx, our bodies are usually still infected. So altho a period on abx may mess w/ the  test results, the results may still be very significant.  And the abx would be more apt to cause a false negative than a false positive, and I intend this to mean that there are really no false positives on the WB, except when too many INsignifican't bands are positive.
