Avatar f tn Anyone know the accuracy of the western blot test? Sent to Igenex by my LLMD. Just curious how accurate it is. I have had an INACCURATE ELISA already so it worries me. I am on Calirthromycin and Doxy right now and herxing really bad right now.
Avatar n tn What is/are the urine test(s) definitive for the diagnosis of untreated Lyme Disease?
Avatar m tn The ELISA has about a 40% accuracy rate if I recall correctly. It is a poor screening test for lyme. The fact that the doctor does not know this leads me to believe he or she is not knowledgeable about lyme.
1498017 tn?1289003772 I am wondering is anyone that has a current diagnosis of Lyme Disease had a negative ELISA test when first tested. I had a rash with a bullseye a few years ago and have been going downhill ever since. All my symptoms match Lyme Disease but my test was negative. After some testing my doc thinks I have myasthenia gravis, but I have more symptoms that do not go with that disease. I did not go to the doc when I noticed the bite because it didn't hurt. I just thought it was a spider bite.
Avatar f tn Thats a difficult question. Elisa lyme test a is common test doctors use to diagnose Lyme. It test for the antibodies in your blood. As well as the Western blot test which is usually used after Elisa to confirm. Western blot is more accurate, but the accuracy rate among these types of test is about 40-60% depending on when you contracted the disease. The best way to rule out Lyme's is to see a LLMD doctor who specializes in Lyme and can run a specialized panel.
Avatar m tn IGeneX will not, to my reading and understanding, produce a false positive Lyme test, because the test is positive *only* in the presence of Lyme bacteria: the test looks for DNA [genes] from the Lyme bacteria. (The older tests, W.blot and ELISA, do have the problem of false negatives, but I have not heard of any of the three tests [W.blot, ELISA, IGeneX PCR] producting false positive results.
Avatar m tn My interpretation is #1 is the standard screening test (ELISA). If the test is positive then the western blot is done automatically. This is the standard testing for lyme that most non-lyme specialists order. I just wonder how much it costs if the test is negative and no further testing is done. It should be a lot less. The ELISA is not very reliable and misses a large percentage of lyme cases. #2 is the western blot in itself. I think this is what it means but I'm not sure.
Avatar n tn There is a newer, different test for Lyme, called a polymerase chain reaction [PCR] test that Lyme specialists often use in addition to the Western blot and ELISA tests. The Wblot/ELISA tests rely on your immune system reaction to determine whether you have a positive (+) test or a negative (-) test for Lyme.
5871250 tn?1377708161 the standard elisa test for lyme is worthless you nee to get tested thru Igenex Lab google it and call them for a test kit its 200 bucks for western blot igm igg that's what u need to do the other tests are a waste of time and not accurate for lyme
5871250 tn?1377708161 Why do they rely on ELISA tests had a heated discussion with my Infectious Diseases consultant on the 20th of August that the ELISA test is very "sensitive" for lyme disease and I heard from the chaps at the southampton branch here in the uk that on the 14th August they carried out a western blot however my consultant told me that they don't carry out the second test unless the ELISA is positive.
Avatar f tn Greetings -- I'm with Katya, that a bit more investigation may well be worthwhile. IGeneX has a number tests, and your MD may want to test you (perhaps in addition to Western blot) run a test called PCR, short of polymerase chain reaction. PCR tests look in your blood for the DNA (unique cellular material) of the Lyme bacteria, and it quite reliable ...
Avatar f tn The quotations below are from the Mayo Clinic website, discussing Lyme testing: 1 -- ELISA can sometimes give a false positive result: "Enzyme-linked immunosorbent assay (ELISA) test: The test used most often to detect Lyme disease, ELISA detects antibodies to B. burgdorferi. But because it can sometimes provide false-positive results, it's not used as the sole basis for diagnosis.
Avatar n tn m assuming your doc ran an ELISA. That particular test only has about a 30-70% accuracy depending on the lab, if that, and is well-known for it's false negatives. I strongly suggest getting both IgG and IgM western blots done for lyme. Make sure the lab doing the test includes bands 30 and 34 (these are sometimes excluded on testing).
Avatar m tn hi all, i had unprotected vaginal sex with lady unknown HIV status , after 20 days i took screening test using ELISA methode 4th generation the result is negative , and then on 35 days i took same test but the lab technician told me that he only detect antibody because P24 antigen detected on few weeks after exposure , meaning on 2nd test ( 35 days ) only antibody test but using ELISA 4th gen. any expert can explain how the accurate my test?
Avatar m tn I read that those IG test are not reliable. Now I worry what if I have chronic Lyme? I cannot remember ever having been biten by anything but who knows. But I also don't know which tests are 100% reliable. Are there even 100% reliable tests? Like I said I have a lot of symptoms which also fit into the very long list of Lyme symptoms. This also makes it hard to really tell if I might have it.
Avatar m tn got a tridot test done at 6 weeks it has come negative, but I have read its accuracy is only 99% should i undergo Elisa test, plz help I am in great mental delima and also which is better Tridot test or Elisa. Thanx in Advance May I request Teak or somebody to answer the question.
Avatar n tn Did not ask about accuracy but about the the test included within the Elisa 'package'. AB or AB+AG. Teak or Lucy ?
