Chronic Lyme And Negative Western Blot
what is difference between IgM and IgG for western blot for lyme. positive for IgM but not IgG, what does that mean? tks
Recent infection: Hi. IgM is present only with recent infection. After IgM levels fall away, IgG takes over for ongoing and recurrent exposure to antigen. (The antibodies in this picture are IgG's). I'm glad your doc was on the ball. She/he may have saved you a world of hurt by making the diagnosis promptly. Good luck! ...Read more
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
No: Possible, but probably not. The IgM WB is sensitive in the first 4 days to 6 weeks. ...Read more
With lyme disease you have ELISA and western blot but what if you tested ELISA negative is Lyme disease impossible? Or wise to do western blot?
Lyme antibody positive and western blot negative. Where can I find a complete list of other id's associated with a positive igm/igm antibody screen?!
Probably have Lyme!: I don't know where to find such a list as I am not sure the causes of a false positive are known, but, esp. If the western blot did not include the 34 ; 39 bands i would not rely upon it; please do the igenex western blot, which is much more sensitive ; specific for lyme. Even if that is negative 20-30% with lyme can have a negative WB test. Other tests may be indicated. See http://bit.Ly/1aaqjgc. ...Read more
High disease area?: The Western Blot is the 2nd (after the ELISA) in a 2-step process. An individual in an area where Lyme disease is common & with high exposure to Lyme-disease carrying tick bite who has been bitten by an engorged tick is highly likely to have Lyme disease if these tests are positive. Without these risk factors, a positive test could be falsely positive. ...Read moreSee 1 more doctor answer
How can someone test positive for two Lyme-specific bands on western blot and NOT have been exposed to Lyme disease? What is magic about 5 bands?
Immune complexities: Lyme disease is caused by a certain type of bacteria called a 'spirochete'- they are a whole class actually of bacteria and believe it or not can be found commonly in the mouth or elsewhere in the environment. You have to reach a certain 'threshold' with Lyme testing because there could be some cross-reactivity coming from these other types of bacteria. The immune system is extraordinarily complex ...Read moreSee 1 more doctor answer
Yes!: No lab test is perfect, including the westen blot for lyme. There is an approximately 4% chance of a positive being a "false positive" test. There is also an approximately 20% chance of false negatives, someone with lyme not having a positive western blot. This is why lyme is ultimately a clinical diagnosis, with labs used to support a diagnosis. Other tests may also be useful. Please see comment:. ...Read more
