Aiding in the diagnosis of Lyme disease caused by infection with Borrelia species endemic to Europe and Asia, including Borrelia garinii and Borrelia afzelii
This test should not be used to screen the general population. It is only intended for use in patients with recent travel to and exposure to ticks in Europe or regions of Asia who are suspected to have Lyme disease caused by Borrelia species endemic to Europe/Asia.
Highlights
The first-tier screening assay detects antibodies to the VlsE protein. C6 is a conserved epitope in the VlsE protein. Therefore, this assay will detect antibodies to C6, in addition to other epitopes on VlsE and pepC10.
This test should be ordered for evaluation of possible Lyme disease in individuals who have recently traveled to Europe or Asia and who have been exposed to or bitten by a tick.
This panel includes a screening test capable of detecting antibodies to the most common Lyme disease causing Borrelia species found in Europe and Asia. Specimens with positive or equivocal results by the screening assay will be reflexed to a supplemental immunoblot able to detect antibodies to Borrelia afzelii or Borellia garinii, both Lyme disease-causing Borrelia species endemic to Europe and regions of Asia.
The immunoblot does not distinguish between infection with B afzelli or B garinii.
Patients infected with B afzelii or B garinii may be serologically negative by diagnostic assays used in North America, which are designed to detect antibodies to the Borrelia burgdorferi B31 strain.

Ordering Guidance
This test should only be ordered for patients who present with Lyme disease symptoms and who have recently returned from travel to Europe or Asia. These patients may be infected with Lyme disease causing Borrelia species endemic to Europe (eg, Borrelia afzelii, Borrelia garinii), which may not be detected using diagnostic tests in North America. The North American serologic assays for Lyme disease are developed specifically for detection of antibodies to Borrelia burgdorferi (strain B31), the most commonly encountered species.
Patients who are suspected to have Lyme disease who have not traveled to Europe should be tested by the LYME / Lyme Disease Serology, Serum assay for detection of antibodies specifically to B burgdorferi, the most common agent of Lyme disease in North America.

Clinical Information

Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Lyme disease (LD) is caused by infection with a member of the Borrelia burgdorferi sensu lato complex. Among the genospecies within this complex, B burgdorferi sensu stricto (B burgdorferi) is the primary agent causing LD in North America. While B burgdorferi is also found abroad, Borrelia garinii and Borrelia afzelii are more prevalent in Europe and regions of Asia. These spirochetes are transmitted to humans through the bite of Ixodes species ticks, primarily Ixodes ricinus and, to a lesser extent, Ixodes persulcatus, both of which are found throughout Europe, the Baltic regions, and parts of Asia. Therefore, residents of, or travelers to, these areas who are bitten by ticks are at increased risk for LD caused by a European Borrelia species.
Transmission of LD-associated Borrelia requires at least 36 hours of tick attachment. Approximately 80% of infected individuals will develop a unique expanding skin lesion with a central zone of clearing, referred to as erythema migrans (EM; stage 1). In the absence of treatment, patients may progress to early disseminated disease (stage 2), which is characterized by neurologic manifestations (eg, meningitis, cranial neuropathy, radiculoneuropathy) and is often associated with B garinii infection. Patients with late LD often present with intermittent or persistent arthralgia, most often associated with B burgdorferi infection, or with acrodermatitis chronica atrophicans, typically due to infection with B afzelii.
Diagnosis of LD is currently based on a 2-tiered serologic testing algorithm to detect antibodies to LD-associated Borrelia species. Importantly, patients may be seronegative until 2 weeks post onset of symptoms. An IgM-class antibody response usually peaks 3 to 6 weeks after infection but may persist for years in some cases. IgG-class antibodies to Borrelia spirochetes are detectable 2 to 3 weeks postinfection and may remain elevated for years after resolution of symptoms. In patients with EM, culture of skin biopsies obtained near the margins of the rash are frequently positive, though this technique is not commonly available. In late (chronic) stages of the disease, serology is often positive and is the diagnostic method of choice. Polymerase chain reaction testing may also be of use in these late stages if performed on synovial fluid or tissue.
Early antibiotic treatment of Lyme disease can resolve clinical symptoms and prevent progression of the disease to later stages. Also, if provided early in disease, treatment may suppress the immune response to the bacteria leading to negative serologic results.
The 2-tiered testing algorithm for LD involves an initial screening assay for detection of total antibodies to LD-causing Borrelia species. For this algorithm, the C6 enzyme-linked immunosorbent assay (ELISA) is used to screen all specimens, and those with positive or equivocal results are reflexed for supplemental testing by immunoblot for detection of IgM and IgG antibodies to LD-causing Borrelia species. Importantly, while most screening ELISAs detect antibodies to all major LD-associated Borrelia species, the immunoblot assays used for supplemental testing in North America are specifically designed to detect antibodies to the B burgdorferi B31 strain. Despite similarity between the genospecies, the North America immunoblot tests have a reported sensitivity of approximately 50% for LD caused by the European Borrelia species (eg, B afzelii and B garinii). In order to improve upon the ability to detect antibodies to the European Borrelia species, immunoblot tests designed to detect IgM- and IgG-class antibodies B garinii, B afzelii, and B burgdorferi are used for supplemental testing of all specimens with positive or equivocal results by the LD screening ELISA.

Negative result:
No antibodies to Lyme disease Borrelia species (eg, Borrelia afzelii, Borrelia burgdorferi, Borrelia garinii) detected. Repeat testing on a new specimen collected in 2 to 3 weeks should be considered if acute Lyme disease due to one of these Borrelia species is suspected.
Equivocal result:
Not diagnostic. Supplemental immunoblot testing has been ordered by reflex.
Positive result:
Not diagnostic. Supplemental immunoblot testing has been ordered by reflex.

The predictive value of the assay is a function of the pretest probability of Lyme disease in the population tested. Hence, only patients with clinical symptoms of Lyme disease with recent travel to or residence in Europe or parts of Asia should be tested for Lyme disease caused by Borrelia species endemic to Europe.
A negative result does not exclude the possibility of infection with Lyme disease-associated Borrelia species, including Borrelia afzelii or Borrelia garinii.
A positive result is not definitive evidence of infection with Lyme disease-associated Borrelia species. Supplemental testing of all specimens that result as positive or equivocal by the Lyme disease screening enzyme-linked immunosorbent assay (ELISA) require supplemental testing by immunoblot for IgM- and IgG-class antibodies to Borrelia species endemic in Europe and regions of Asia.
False-reactive screening ELISA results may occur in patients with other disease conditions, including syphilis, periodontal disease, rheumatoid arthritis, systemic lupus erythematosus, and other autoimmune diseases.
Test results should be used in conjunction with exposure history, travel history, clinical presentation, and other clinical findings.

The first-tier Lyme disease screening enzyme-linked immunosorbent assay (ELISA) used is the Zeus ELISA Borrelia VlsE1/pepC10 IgG/IgM test system. This test system is designed to detect IgG- and IgM-class antibodies (not differentiated) in human sera to VlsE1 and pepC10 antigens. Diluted test sera are incubated in antigen coated microwells. Any antigen-specific antibody in the sample will bind to the immobilized antigen. The plate is washed to remove unbound antibody and other serum components. Peroxidase conjugated goat antihuman IgG and IgM are added to the wells and the plate is incubated. The conjugate will react with IgG and IgM antibodies immobilized on the plate. The wells are washed to remove unreacted conjugate. The microwells containing immobilized peroxidase conjugate are incubated with peroxidase substrate solution. Hydrolysis of the substrate by peroxidase produces a color change. After the incubation period, the reaction is stopped, and the color intensity of the solution is measured photometrically. The color intensity of the solution depends upon the antibody concentration in the original test sample.(Instruction manual: Borrelia VlsE1/pepC10 IgG/IgM Test System.
