Serological testing of serum for the diagnosis of Lyme disease. The most commonly used tests look for antibodies to the Borrelia species that cause Lyme disease in the UK and Europe, but they also detect infections from strains of Borrelia from the US.
When do you test for Lyme serology?
Testing should only be performed when clinical evidence suggests the diagnosis of Borrelia infection or related etiological conditions observed by the physician. This test will not distinguish results that are both IgG and IgM positive from results that are either IgG or IgM positive.
What does positive Lyme serology mean?
A positive result means that Borrelia antibodies were found and that you may have had or have Lyme disease. False-positive results sometimes do occur. This means the test could say you have the infection when you don’t.
What blood tests indicate Lyme disease?
The two most common diagnostic tests for Lyme disease are the enzyme-linked immunosorbent assay (ELISA) and the Western blot. These Lyme disease tests allow physicians to visualize the reaction between antibodies in an infected person’s blood to specific antigens or parts of the bacteria that cause Lyme disease.
What is a normal Lyme level?
Reference Range Normal levels vary depending on the laboratory assay performed, as follows. Borrelia burgdorferi antibody enzyme immunoassay (Lyme index value) : < 0.9 = negative. 0.91-1.09 = equivocal.
Would Lyme disease show up in routine blood work?
You do not usually need tests to show that you have Lyme disease. In most cases, there’s a clear sign of Lyme disease—a painless, spreading rash that often grows to look like a bull’s eye.
What is serology test for Covid?
Antibody (Serology) Testing for COVID-19: Information for Patients and Consumers. SARS-CoV-2 antibody (often referred to as serology) tests look for antibodies in a sample to determine if an individual has had a past infection with the virus that causes COVID-19.
What is the difference between immunology and serology?
Immunology is the study of the body’s immune system and its functions and disorders. Serology is the study of blood serum (the clear fluid that separates when blood clots).
What is Lyme serology?
4.1 Introduction Serology is the only standardized type of clinical diagnosis of Lyme borreliosis (Lyme disease) in the USA. It is also the only type of diagnostic testing approved by the US Food and Drug Administration (FDA). Of the 77 devices cleared by the FDA for in vitro Borrelia burgdorferi sensu stricto, diagnosed by serology.
When should testing be performed for Borrelia infections?
Testing should only be performed when clinical evidence suggests the diagnosis of Borrelia infection or related etiological conditions observed by the physician. This test will not distinguish results that are both IgG and IgM positive from results that are either IgG or IgM positive.

Can we isolate and culture B burgdorferi to diagnose Lyme disease?
However, the ability to isolate and culture B. burgdorferi is essential in Lyme disease research, and culture remains the gold standard to confirm the diagnosis. Methods that would improve sensitivity and simplify the procedure, so it could be adopted more extensively, are needed.
