How do you analyze Western blot results?
The 4 Important Steps for Western Blot Quantification
- Find the Linear Range. For quantitate analysis of an image you must ensure your image was captured in a manner sensitive enough to detect change, in what we call the “linear range”.
- Subtract Background. Sadly, most Western blots and image captures are infiltrated with random imperfections.
- Normalize.
- Graphs and Stats.

What type of test is Western blot?
The Western blot assay is a method in which individual proteins of an HIV-1 lysate are separated according to size by polyacrylamide gel electrophoresis. The viral proteins are then transferred onto nitrocellulose paper and reacted with the patient’s serum.

What does a positive Western blot test mean?

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).
What is the Western blot test for Lyme disease?
The Lyme Western Blot is a qualitative immunoassay in which antibodies specific to the B. burgdorferi antigens on a membrane strip are visualized. It is a qualitative test and is generally more sensitive and specific than the ELISA and IFA tests.
