Lyme Disease Generally, Lyme blood testing is helpful in a patient who has symptoms compatible with Lyme disease, who has a history of a tick bite at least a month prior, or who has unexplained disorders of the heart, joints, or nervous system that are characteristic of Lyme disease.

Lyme disease Lyme disease is diagnosed clinically based on symptoms, objective physical findings (such as EM, facial palsy, or arthritis), or a history of possible exposure to infected ticks, as well as serological blood tests.

Understanding the EIA Test Several types of EIA tests exist. Validated and FDA-approved EIAs include “ELISA” (enzyme-linked immunosorbent assay) and “ELFA” (enzyme-linked fluorescent immunoassay). Lyme disease testing measures a person's antibody (or immune response) to the bacteria that cause Lyme disease.he Western blot or other FDA-approved type of immunoblot can help distinguish patients who have Lyme disease from those with other conditions. Additional information on the EIA/ELISA test is available.

- But Lyme disease is not Morgellons! Using the DNS standard test by means of the Polymerase-chain-reaction (PCR), until recently, PCR's have been used as a good means for detection of many un-identified infections, as well as their identification by means of certain customary blood tests (Sero-diagnostic).

However, if a person has central nervous system symptoms, such as meningitis, then IgM, IgG, and western blot testing may sometimes be performed on cerebrospinal fluid (CSF) . healthy adult who has never been infected by B. burgdorferi bacteria will not have any antibodies. If a person has signs and symptoms and the initial EIA or IFA and western blot tests are positive, then it is likely that the person has Lyme disease.

Lyme Disease Diagnosis Lyme Disease Diagnosis. Lyme disease is a clinical diagnosis—based on your medical history, symptoms and exposure to ticks. Because the typical diagnostic tests for Lyme are so insensitive, a negative test result does not mean you don’t have Lyme. There are many reasons why someone who actually has Lyme may have a negative test result.

ELISA Test for Lyme Disease The most common Lyme disease test is the enzyme-linked immunosorbent assay (ELISA). This test has been available for Borrelia burgdorferi since 1984 and most commercial ELISA tests use a whole cell sonicate of the bacteria.

- The immunoblot is a laboratory test that looks for antibodies the body makes against different molecules, or “antigens,” that are part of the Borrelia burgdorferi bacteria. Western Blots were the first type of immunoblot developed for Lyme disease testing.

Lyme Disease Tests Lyme disease tests are used to determine if a person with characteristic signs and symptoms has been infected by the bacteria Borrelia burgdorferi. The tests detect antibodies produced by the immune system in response to the infection.f the IgM and western blot are negative but the IgG is positive, then either the person has recovered from Lyme disease or this is due to cross reactive antibodies and the symptoms are due to another cause.

Lyme Disease Diagnosis Two-tier Testing. The most common diagnostic tests for Lyme disease are indirect ones. They measure the patient’s antibody response to the infection, not the infection itself. The two most-used antibody tests are the enzyme-linked immunosorbent assay (ELISA) and the Western blot.

Laboratory tests that are not recommended Some laboratories offer Lyme disease testing using assays whose accuracy and clinical usefulness have not been adequately established. Examples of unvalidated tests include: Capture assays for antigens in urine. Culture, immunofluorescence staining, or cell sorting of cell wall-deficient or cystic forms of B. burgdorferi.

Lyme Disease Tests When someone does not have typical symptoms or a history of a tick bite and has not been in a region where Lyme disease is prevalent, then the healthcare provider may rule out other causes for the person's symptoms before suspecting and testing for Lyme disease. healthy adult who has never been infected by B. burgdorferi bacteria will not have any antibodies. If a person has signs and symptoms and the initial EIA or IFA and western blot tests are positive, then it is likely that the person has Lyme disease.

Western Blot Test Western Blot Test. The Western blot test for Lyme disease is usually used following a positive or indeterminate ELISA (or IFA) test which is more sensitive, but less specific, than the Western blot.

Lyme Disease Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks. Laboratory testing is helpful if used correctly and performed with validated methods. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics.

Laboratory Tests Laboratory Tests. Lyme disease is recognized as a clinical diagnosis that is supported by diagnostic tests. However, a patient may have Lyme disease but not test positive on a particular test. Many different tests may be ordered for an individual patient for two reasons. First, the internist will want to rule out other possible causes of the persistent symptoms that may not yet have been considered.

Lyme Disease Tests Lab tests can detect two different classes of antibody, IgM and IgG. 1  Borrelia IgM (immunoglobulin M) antibodies are usually detectable in the blood about two to three weeks after exposure. IgM levels increase to maximum concentrations at about six weeks and then begin to decline.
