New York State Grants Approval of IGeneX’s Newly Developed Lyme ImmunoBlot Tests

August 7, 2018

PALO ALTO, Calif.--(BUSINESS WIRE)--Aug 7, 2018--The Division of Laboratories of the Department of Health of the State of New York has approved IGeneX’s newly developed Lyme ImmunoBlots (IgM and IgG), making it immediately available to New York practitioners.

Now, instead of sourcing test antigens from only one or two species of sonicated Borrelia, the ImmunoBlot is comprised of specific recombinant antigens from several species of Borrelia burgdorfer i. The ImmunoBlot therefore detects the following US and European species of Lyme Borrelia: B. burgdorferi B31, B. burgdorferi 297, B. mayonii, B. spielmanii, B. californiensis, B. valaisiana, B. afzelii and B. garinii and makes the P31 epitope confirmation test unnecessary.

To test for all the above Borrelia burgdorferi species by Western blots, eight individual IgM and eight individual IgG tests are required. Performing 16 Western blots on each patient sample is expensive and impractical as opposed to just two tests with the Lyme ImmunoBlots.

“The Lyme ImmunoBlot is intentionally more inclusive for Borrelia burgdorferi sensu lato than the currently available Western blot s because we now know that other species such as B. mayonii, B. californiensis and B. spielmanii all cause disease in the US,” said Dr. Jyotsna Shah, CEO of IGeneX. “With the increase of international travel in the last 10 years, people can get infected at home, other parts of the US or Europe depending on their lifestyle. Thus, it is important to have available a test that can detect the infection irrespective of where it was acquired.”

More Comprehensive Detection

The Lyme ImmunoBlot IgM detects the five following recombinant protein groups: P93, P41, P39, P31, and P23. Furthermore, the Lyme ImmunoBlot IgG detects these twelve recombinant protein groups: P93, P66, P58, P45, P41, P39, P34, P31, P30, P28, P23, and P18.

High Accuracy Across the Disease Spectrum

The accuracy of the Lyme ImmunoBlot has been established by exhaustive testing. The sensitivity with well-characterized samples has been shown to be greater than 93% whereas the two- tier testing recommended by CDC has a sensitivity of about 57.6% (Waddell LA et al. PLoS ONE. 2016;11(12):e0168613. doi:10.1371/journal.pone.0168613). Additionally, the ImmunoBlots detect the full spectrum of disease: early, active and late-stage disease. This high degree of sensitivity does not come at the cost of specificity. The specificity of the Lyme immunoblot is equivalent to CDC 2-tier testing (ELISA or IFA followed by Western blots).

New York State Department of Health Approval

The Clinical Laboratory Evaluation Program, Wadsworth Center, New York State Department of Health has approved the IGeneX Lyme ImmunoBlot ( https://www.wadsworth.org/igenex-inc-reference-laboratory-12 ), making it available to all qualified New York practitioners and their patients. IGeneX works swiftly to ensure that this remarkable test can be utilized immediately.

The Wadsworth Center, a division of New York State Department of Health, is a science-based community committed to protecting and improving the health of New Yorkers through laboratory analysis, investigations, and research, as well as laboratory certification and educational programs. The Center serves a vital role in the New York State Department of Health’s efforts to protect and promote the health of New York’s citizens.
