A condition caused by borrelia burgdorferi. Acute symptoms can include bullseye rash, headaches, joint pain, fever, and flu-like sx.

Is it possible for a negative Lyme disease test to be wrong? I read online it's correct maybe 60% of the time....
About lab tests...: If a person does a lab test that is correct 60% of the time, that may mean the test result is incorrect 40% of the time. If a patient's symptoms and history are suggestive of Lyme disease, a Lyme disease positive test result will be more likely to be a true positive. If symptoms and history are NOT suggestive of Lyme disease, a positive test result has higher chances of being a false positive. ...Read more
I got a Lyme disease test done.& IgG 66 came positive out of the other 10 bands. What does this mean? Do I have Lyme or had it? Should I worry? Thanks
Not enough info: This test is not evidence of lyme but also not proof you don't have it! Ultimately lyme is a clinical diagnosis. 20-30% of those who have it never have a positive western blot. It's really important that the test include the 31 & 34 bands & most labs don't check it- igenex is the best lab for a thorough test. See a doc who uses igenex as that is someone able to make a proper diagnosis. See comment:. ...Read more
What is the best Lyme disease test? I've had the basic blood test done, came back negative, but is there a more thorough test to rule it out?
Thorough WesternBlot: The screen many doctors use, the elisa, only detects about half of those with lyme. A much more sensitive and specific test is the western blot, but i strongly advise doing this through ignenex in palo alto, a specialty lab, as the test offered by most other labs does not include tests for antibodies to the 31 & 34 kda antigens, which are the most specific antigens for lyme! Please see my comment. ...Read more
If I have a negative lyme disease test, but antibiotics appear to be addressing my symptoms, is there any way to tell what caused the symptoms?
Not a clue: When you submit a question, you must provide enough background information for site docs to review. You provide no info beyond a negative test result. No history, no exam findings, no initial problem. This is not a chat room, so any question must be complete, We do not have access to any previous question or data you upload. ...Read more
What to do if I did a Lyme disease test and it showed IgG p58 ab. Positive a can you explain what that means?
Nothing by itself: A single positive IgG band means nothing. Was the screen positive? How many other IgG and IgM bands were positive? You should discuss all of this with the doctor who ordered the test. ...Read more
If I had positive serum western blot Lyme Disease test, but my Spinal Fluid didn't turn up positive for any Antibodies, does that mean I don't have Lyme in my nervous system?

I've been put on Lymecycline for Lyme disease after 7 months undiagnosed. How long can I expect it to take till I start feeling improvement?
Possibly never...: Antibiotics in adequate doses usually cure Lyme if started within a week or 2, but are seldom curative when you've been infected for 7 months. Unfortunately, they may do more harm than good at this stage. The best treatments now are herbs & antibiotics. It's important to be tested & treated for co-infections like Babesia & Bartonella. Find a doc who is knowledgeable in treating Lyme. See comment: ...Read more

Depends on the test:
There are many tests for lyme- elisa, western blot, ifa, pcr, cultures. Testing can be expensive. If you have limited resources I advise the igg & IgM western blot from igenex- their test is more thorough & sensitive than other labs. It costs about $200.
No single test totally proves or disproves if one has lyme- it is a clinical diagnosis, but the right tests are very helpful. ...Read more

I have to take a ELISA test today for Lyme disease but I was just wondering how does ELISA test work?
Sandwich assay...yum: Elisa = enzyme-linked immuno sorbent assay. Done by adding serum from a subject to a plate w/antibody against the infection you're testing for on its surface. The antigen (or protein) from the infection binds to the antibody on the plate. Then another antibody to the infection w/color signal chemical attached is added on top and binds to the antigen. If infection is there color can be measured. ...Read more

Should I go and take a test for Lyme disease? I got two tick bites on monday and pulled them out. I felt really sick last night and a little sick now
It is always a good idea to get yourself checked out after a tick bite. There is a simple blood test that can be done in a lab which will specifically test for exposure to lyme disease. The results will take a few days to be resulted. In the meantime, if rest at home is not helping you at this time you may want to seek medical advice in person.
Good luck. ...Read more
How long willit take for the "bulls eye" to come up to show you have Lyme disease from a deer tick?
3-30 days or never: A bulls-eye rash (erythema migrans) after a tick bite is considered a sure sign that one has been infected with lyme & appears 3-30 days after the bite (usually 3-7 days). However, half or more of those proven to have lyme do not recall this rash. One should therefore not wait to see if they develop this rash to seek preventive treatment. The sooner treatment is started after exposure the better! ...Read more
Depends: If you caught the disease early, in stage 1 with the initial fever and rash, fever should resolve within a couple of days of starting the antibiotic. If the disease had progressed further before treatment was initiated, it may take a lot longer to become fever free — even 10-14 days. Make sure you don't skip doses and let your doc know if any new symptoms or you're not feeling better. ...Read more

Lyme disease ab plus reflex to igg, igm-wb blood test done today. How long for results and how accurate are they?
About a week: The regular lyme test is specific but not very sensitive. There can be many reasons for a false positive result. If it is positive on the screening test it is then sent for the more sensitive western blot test. If the igm test is positive it could represent a recent exposure to lyme disease if the igg is positive it indicates a more distant orast exposure. If the igm is positive you should be eval. ...Read more
How long do antibodies remain detectable in the blood? I had a clear ELISA for Lyme disease after recurring lightheadedness and brain fog after a possible bite when hiking in the uk but the test was a good 10 months later -would it still be reliable?
Last for years and some others (such as chicken pox) last a lifetime..... It is VERY unlikely that you had a Lyme exposure if the tests are negative in 10 months!
Hope this is helpful
