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

In practice, it usually refers to identifying antibodies in the serum, which are typically formed in response to an infection (against a microorganism), against other foreign proteins (for example, to proteins in a mismatched blood transfusion), or to one's own proteins (in ...Read more

Can you have lyme's disease, even if a blood test rules it out?

Can you have lyme's disease, even if a blood test rules it out?

Yes: A negative test for lyme disease does not rule out lyme disease, because all of the tests currently available for lyme have a track record of many false negatives. That means that as many as 50% of patients with lyme disease have tested negative. A reasoable diagnosis should depend on a history of activity in a lyme endemic area, a devel. Of symptoms over time, and lab testing altogether. ...Read more

I had a blood test (Western Blot), to check for Lyme Disease. The results look strange (0.45). This doesn't look like the result of any WB test I have?

Probably not Lyme: Your Western Blot would need to be above 5 for a conclusive confirmation of Lyme disease. Unless you also had known tick bite, low-grade fever, "erythema migrants", you probably had a viral illness that should resolve on its own. Do discuss this with your primary medical provider or specialist if symptoms persist. ...Read more

Will the regular blood test and western blot test for Lyme disease rule out someone having it?

Will the regular blood test and western blot test for Lyme disease rule out someone having it?

It is a good test..: Enzyme-linked immunassay is a sreening test which if positive will be confirmed with a western-blot (=standard of testing). Although not absolutely 100%, a negative western blot is a good bet that there is no lyme at the time of testing. Early disease/infection may have negative test, thus recommended retesting in about 3 wks. Lyme dna testing is better, but more expensive. Consult doc..Good luck. ...Read more

Yes to both: It is fairly common for lab tests for lyme disease to be a false negative. The cdc criteria for a positive test is so strict that it might miss up to 50% of patients who have lyme disease. ...Read more
