What is the best test for Lyme disease?

The two most common diagnostic tests for Lyme disease are the enzyme-linked immunosorbent assay (ELISA) and the Western blot. These tests allow physicians to visualize the reaction between antibodies in an infected person’s blood to specific antigens, or parts of the bacteria that causes Lyme disease.

When is Western blot test performed?

The western blot is routinely used for verification of protein production after cloning. It is also used in medical diagnostics, e.g., in the HIV test or BSE-Test. The confirmatory HIV test employs a western blot to detect anti-HIV antibody in a human serum sample.

How does the Western blot test work?

Western blot is often used in research to separate and identify proteins. In this technique a mixture of proteins is separated based on molecular weight, and thus by type, through gel electrophoresis. These results are then transferred to a membrane producing a band for each protein.

How can I improve my Western blot?


  1. Reduce primary antibody concentration.
  2. Decrease the amount of total protein loaded on gel.
  3. Adjust membrane blocking conditions.
  4. Increase number of washes.
  5. Verify the specificity of the antibody.
  6. Blot with the secondary antibody alone.
  7. If bands develop, choose an alternate secondary antibody.

What are the 3 stages of Lyme disease?

Although Lyme disease is commonly divided into three stages — early localized, early disseminated, and late disseminated — symptoms can overlap. Some people will also present in a later stage of disease without having symptoms of earlier disease.

How long does a Western blot Lyme test take?

Test results are usually available in 1 to 2 weeks. Normal (negative): No antibodies to Lyme disease bacteria are found.

How much does a Western blot test cost?

Category HIV Negative on ELISA Test HIV Positive or Indeterminate on ELISA Test
Three ELISA tests $10
Western Blot $35
Risk assessmenta $2 $ 2

How long does Western blot take?

Mischnick agrees that one of the biggest limitations in blot optimization is time. “It can take up to 8 hours to generate and detect a Western blot,” she says.

What is the difference between Elisa and Western blot testing?

A positive Western Blot indicates the presence of viral antigen – which very often means live virus – in our patient. ELISA (Enzyme-Linked ImmunoSorbent Assay) is a related technique, but instead of using antibodies to detect virus antigen, it uses virus antigen to detect antibody.

What does a positive Western blot test mean?

A positive result on both initial and confirmatory tests means that your signs and symptoms are likely caused by Lyme disease. A positive result for IgM antibody but negative results for IgG and Western blot may mean that you have a very recent infection or a positive when you do not have Lyme disease (false-positive).

Is there an eastern blot?

The eastern blot, or eastern blotting, is a biochemical technique used to analyze protein post-translational modifications including the addition of lipids, phosphates, and glycoconjugates. It is most often used to detect carbohydrate epitopes.
