Lyme Dot Blot (2 samples)

$170.00

Lyme Dot-Blot Assay (LDA) is a qualitative immunoassay for the direct detection of Borrelia burgdorferi-specific antigens in a patient urine sample using anti-B. burgdorferi antibodies.

Purpose
The antigens present in the urine sample are immobilized onto a membrane in a Dot-blot format and incubated with anti-B. burgdorferi-specific antibodies. After washing the bound anti-B. burgdorferi-specific antibodies, they are reacted with anti-rabbit IgG, which is visualized by an enzyme/substrate reaction.

• Requires urine samples, and are therefore more practical tests for babies and infants, as the sample is easier to catch.
• Doctors are able to run different antibiotic challenges to determine
whether treatment is working to draw out the Lyme bacteria in the urine.
• If the initial Lyme panel tests on a patient’s blood samples are negative, including PCR, but symptoms for Lyme disease are present, the Lyme Dot-blot assay on urine can be helpful in making the diagnosis.

Positive: B. burgdorferi antigens
detected

Negative: B. burgdorferi antigens not
detected

  1. Negative tests do not exclude diagnosis of Lyme disease
  2. Cross-reactions with Leptospira may occur.
  3. False positive may occur for patients with a Urinary Tract Infection (UTI), currently being treated for a UTI, or who have undergone treatment for a UTI within the last two weeks.
  4. Results should be interpreted in conjunction with other laboratory and clinical findings.
