No: no effect on testing.Get a more detailed answer ›
Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...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
ELISA/West blot.: The 2 main tests are elisa and western blot. Elisa or serology is used for screening to see if there is an antibody response to the b. Burgdorferi spirochete responsible for the disease, while the western blot is a specific test that makes sure the positive response is to this and not a false positive, or a reaction to something else. Pcr, or polymerase chain reaction is another possible test. ...Read more
Yes: There is every reason to believe that lyme disease can be transmitted via blood transfusion. This does not mean that someone with lyme will always transmit it; in patients with lyme PCR tests are often negative, meaning it is not always present in the blood, but it is at times and in that case is almost certain to be transmitted.Certainly some with lyme don't know it & donate blood & transmit it. ...Read more
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 moreSee 1 more doctor answer
How accurate is a blood test for Lyme antibodies in diagnosing whether a patient actually has Lyme disease?
What to ask: In general, accredited labs must validate the performance characteristics for tests they offer. That can be hard for a dx like Lyme where there are few definite criteria and many vague symptoms. Antibody testing is very sensitive, but antibodies themselves cross-react. The most sensitive and specific tests aim to detect DNA specific to the organism. Ask the lab for the performance profile of test. ...Read more
A month: It takes up to a month for the test to be positive. ...Read more
No: Others may argue this point but i firmly believe a positive lyme screen and western blot is essential for the diagnosis. ...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 moreSee 2 more doctor answers

Lyme is caused by borrelia burgdorferi. Acute symptoms can include bullseye rash, headaches, joint pain, fever, and flu like sx. Chronic symptoms can include fibromyalgia symptoms, nerve pain in extremities, mood swings, brain fog, heart problems. Lab diagnosis is not very reliable, and sometimes clinical ...Read more
