![]() ![]() ![]() It is well known for example that concurrent viral infections (such as Epstein-Barr) may result in a false positive Lyme ELISA. Third, a positive test may be a false positive, especially if the positive test is only an ELISA. In this case, the ELISA titer may stay elevated for long periods without a gradual decline. The residual organism may not be biologically active i.e., it might be in a latent or dormant state and thus not causing any disease symptoms. Second, a positive test may also indicate that there is a small amount of persistent infection that is continuing to partially stimulate the immune system. We expect, however, that over time the ELISA titer should decrease in magnitude. That's why tests can stay positive for months to years, even when active infection is no longer present. neurologic features including vertigo or dizziness,Ī blood test may be positive for several reasons:įirst, the positive test may indicate that the person was infected previously by the agent of Lyme disease and the immune system mounted a successful attack which resulted in the long-term production of antibodies against the agent of Lyme disease. The symptoms of late disseminated disease are similar to those of early disseminated disease, but may be more extensive, more severe, and longer lasting. Late stage Lyme disease, which can include post-treatment, chronic, and neurological, occurs months to years after infection, in which the bacteria have spread throughout the body. Numbness or tingling in the hands or feet Facial paralysis on one or both sides (also known as Bell’s palsy) Heart palpitations or shortness of breath (Lyme carditis) Arthritis, especially in the knees or other large joints There is a wide range of possible symptoms at this stage, including: Symptoms in early disseminated Lyme disease:Įarly disseminated Lyme disease occurs days to months after infection, in which the bacteria have begun to spread. While a rash is characteristic of Lyme disease, many people will not develop a rash at all. There can be multiple rashes on the body. ![]() Note: The center of the rash may clear, giving the rash the appearance of a “bulls-eye.” Rashes may take on many different shapes and not all rashes will have a bulls-eye appearance. This rash begins at the site of the tick bite about a week after the bite, and gradually expands. Because they are symptoms often shared with other illnesses, however, it’s important to recognize that they could mean Lyme and you should see a Lyme-treating physician right away. The most common symptoms in acute (aka: early localized) Lyme disease are the ones people are most familiar with. Lyme disease symptoms can vary based on stage of the disease (early, late, post-treatment, or chronic) and if other tick-borne infections are present and can change over time.Īcute Lyme disease (aka: early localized LD) occurs days to weeks after the initial tick bite and infection, in which the bacteria have not yet spread from the site of infection in the skin. This makes it extremely important for patients to keep track of all the symptoms they experience, to share with their healthcare provider. Due to the lack of an accurate diagnostic test, many patients are diagnosed based on a combination symptoms and diagnostic testing. Symptoms can play a key role in diagnosing Lyme disease. Lyme disease can mimic hundreds of other conditions since its symptoms mirror many medical problems such as multiple sclerosis, arthritis, chronic fatigue syndrome or lupus, and is sometimes known as “The Great Imitator” because of this. To make things more confusing, Lyme disease symptoms will also vary from patient-to-patient. Symptoms can also change over time, as the bacteria spreads throughout the body. Lyme disease symptoms are wide-ranging, with more than a hundred different symptoms recorded. If a person doesn't have signs or symptoms of Lyme disease, then the person does not have Lyme disease as the definition of disease requires symptoms. Here is the 2nd important part when it comes to a diagnosis: So if this marker is positive you have at least 2 out of 3 of the IgM markers positive. This marker is called Lyme Disease AB (IGM), Blot and is an aggregate marker for the three IgM results. Or you need to have 5 out of 10 for the positive IgG result. You need to have 2 out of 3 for the positive IgM result In the Western blot test there are three bands for IgM and 10 bands for IgG. IgG remains in the serum for a very long time. IgM antibodies usually disappear after eight weeks post-exposure. IgG antibodies in contrast are a sign of an older infection. ![]() IgM antibodies reflect a relatively recent infection. Two types of antibodies are detected in the Western blot test. ![]()
