Tests for antibodies in the blood by ELISA and Western blot is the most widely used method for Lyme diagnosis. A two-tiered protocol is recommended by the Centers for Disease Control and Prevention (CDC): the sensitive ELISA test is performed first, and if it is positive or equivocal, then the more specific Western blot is run.

Western blot HIV test where the first two strips are negative and positive controls followed by actual tests. The western blot is extensively used in biochemistry for the qualitative detection of single proteins and protein-modifications (such as post-translational modifications).
Several authors have reported that the nephelometric and ELISA FLCs determination is comparable with OCBs as markers of IgG synthesis, and kFLCs behave even better than oligoclonal bands. [ 21 ] Another alternative to oligoclonal bands for MS diagnosis is the MRZ-reaction (MRZR), a polyspecific antiviral immune response against the viruses of ...
There were more than 62,000 cases of Lyme disease reported to the US Centers for Disease Control and Prevention in 2022 – nearly a 70% jump from the annual average from 2017 to 2019, ...
The genomic variations have direct implications on the clinical symptoms of tick-borne Lyme disease. For example, the tick-borne Lyme disease caused by B. burgdorferi s.s. may manifest with arthritis-like symptoms. [9] In contrast, B. garinii’s tick-borne Lyme disease may cause an infection in the central nervous system. [9]
Anti-Pan-Primate IgG [8F1] This is a recombinant monoclonal antibody to pan-primate IgG. This antibody reacts with most primate IgG antibodies, including human IgG. In a research setting the antibody has been used via ELISA to count IgG in supernatants from lung and lymph node tissues from cynomolgus macaques. [32]
Generally a two-step approach is followed. First, a screening test involving IgM and IgG ELISA. If the ELISA screening has a positive or equivocal result, then the second step is to perform a Western Blot as a confirmatory test. Other methods include microscopy and culture (in modified Kelly's medium) of skin biopsy or blood samples.
Diagnosing Lyme borreliosis relies on clinical criteria, with a history of a tick bite and associated symptoms being crucial. Laboratory diagnosis follows a 'two-tiered diagnostic protocol,' involving detecting specific antibodies using methods such as immunoenzymatic assays and Western blot tests, preferably with recombinant antigens.
