ZEUS Scientific Announces U.S. FDA 510(k) Clearance of its ZEUS Borrelia Modified Two-Tiered Testingâ„¢ Algorithm, a Paradigm Shift in Laboratory Testing for Lyme Disease

ZEUS Borrelia MTTT™ algorithm has been shown to significantly improve the detection of early Lyme disease with increased sensitivity over the current standard two-tiered testing (STTT) algorithm(1)

Branchburg, N.J. (PRWeb) July 30, 2019 -- ZEUS Scientific, a leading global diagnostic solutions company, today announced the launch of its ZEUS Borrelia Modified Two-Tiered Testing™ (MTTT) algorithm following receipt of FDA 510(k) clearance from the U.S. Food and Drug Administration. Approval of the MTTT algorithm represents a true paradigm shift in laboratory testing for Lyme disease.

Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common vector-borne disease in the United States and is transmitted to humans through the bite of infected blacklegged ticks. Cases of Lyme disease have almost tripled since the 1990s to more than 300,000 annually(2) and have been found in all 50 states(3). The number of cases in Europe is also on the rise(4).

Serological evidence of exposure is an important aid in the diagnosis of Lyme disease. The Standard Two-Tiered Testing (STTT) algorithm for the serodiagnosis of Lyme disease was devised by attendees of the Second National Conference on Serologic Diagnosis of Lyme Disease (Dearborn, MI) in 1994(5). For 25 years, there have been no significant changes to this algorithm even though several issues with the current STTT algorithm exist, including low sensitivity in the early stages of disease(6) and false positive results associated with IgM immunoblots(7).

Chris Howard, Chief Commercial Officer at ZEUS Scientific remarked, “With nearly 30% of early Lyme disease cases being potentially missed by the current STTT algorithm due to the insensitivity of immunoblot tests(8), we are ecstatic to have successfully improved one of the most challenging aspects of diagnosis: detecting the disease early, before a robust immune response has been developed by some patients.” Howard continued, “Our ZEUS Borrelia MTTT™ algorithm detected up to 30% more acute Lyme disease cases relative to the STTT, significantly reducing the number of missed clinically positive patient samples(1) while maximizing lab efficiency with fully automatable immunoassays.”

The STTT algorithm uses a first-tier immunoassay with equivocal or positive specimens subsequently tested by an immunoblot. Clinical laboratories have been burdened by the complexities and subjectivity of immunoblot testing for years, often needing to send these tests out to reference labs, leading to longer turnaround time for test results, increased resource allocation and higher costs.

ZEUS Borrelia MTTT™ uses the ZEUS ELISA™ Borrelia VlsE1/pepC10 IgG/IgM Test System as a first-tier test with positive or equivocal specimens subsequently tested using a second ZEUS ELISA™ Test System. With this convenient, all-ELISA MTTT algorithm in which two different options have been FDA-cleared, laboratories can now easily and efficiently run first-tier and second-tier testing in-house, benefiting from: 

• Improved sensitivity in early Lyme disease detection
• Fully automatable first- and second-tier testing workflow, not easily achievable with STTT
• Removal of subjectivity in reading Western and immunoblots
• Automation of time-intensive, error-prone manual tasks and elimination of send-out expenses, improving turnaround time and cost efficiencies

“We envisioned a similar MTTT concept more than ten years ago, but were unable to convince regulators of this powerful concept at that time(10). Since then, many other accomplished researchers have repeatedly demonstrated that the MTTT algorithm is clinically more sensitive, yet equally as specific as the STTT algorithm.” stated Mark Kopnitsky, Chief Scientific Officer of ZEUS Scientific. “We are thrilled that we can finally offer this MTTT algorithm to the clinical laboratories and hope to improve their ability to detect cases of early Lyme disease.”

Thirty years ago, ZEUS pioneered the serodiagnosis of Lyme disease with the very first FDA-cleared screening test, and ZEUS continues to pioneer advances in the serodiagnosis of Lyme disease with the first FDA clearance of this MTTT algorithm. As a leader in infectious disease testing, ZEUS Scientific continues to develop the highest quality testing and improved methods to support better patient outcomes.

“The prevalence of Lyme disease is growing and is difficult to diagnose early, at a time when patients need it most,” stated Scott Tourville, Chief Executive Officer of ZEUS Scientific. “This testing paradigm shift is a successful response to longstanding clinical and workflow challenges in the laboratory. I am extremely proud of our research and clinical trial teams in making the promise of MTTT a reality. Labs gain fast, accurate results through an efficient protocol, doctors gain higher confidence in diagnostic assessment, and patients achieve better care with appropriate diagnosis.”
