The multiplexed single-tier InBios Lyme Detect Multiplex ELISA is more sensitive than standard two-tier tests in the early stages of Lyme disease.

There are nearly 500,000 cases of Lyme disease each year in the United States; 10%-20% of them result in the development of a debilitating chronic disease known as post-treatment Lyme disease. Existing standardized and modified two-tier tests (STT/MTT) suffer from poor detection rates in the first weeks of infection, where the antibody response, the basis of diagnosis, is developing but is not robust enough for detection. During this early window, false negative results are common, which leads to delayed treatment and increases the likelihood of developing severe symptoms. The InBios Lyme Detect Multiplex ELISA is a microarray-based assay designed to capture a set of commonly used diagnostic antibodies specific to IMPORTANCE: During initial Lyme disease infection, existing diagnostic tests have poor sensitivity, resulting in a high number of false-negative tests. This is due to the lag between infection and a robust immune response capable of being detected by such tests. With a multiplexed array of nine unique antibody targets specific for
