Lyme Diagnostics
Modified Two Tier Tests (MTTT)

In 2014, the CDC published an article (1) describing a new two-tiered testing algorithm based on use of two EIA tests. This modified algorithm would serve as an alternate to the standard two-tiered EIA + lmmunoblot testing (STTT) algorithm. Following this CDC discussion, the US FDA accepted the proposed testing option and published guidelines (2) for this modified two tiered testing (MTTT) algorithm.

Gold Standard Diagnostics now offers a solution for this new Lyme testing algorithm, which complements our existing market leading Lyme test portfolio. With the addition of the B. burgdorferi lgG/IgM VlsE-OspC EIA test, you can choose which tests and algorithms best meet the needs of your laboratory and your clients.

An example of the MTTT workflow using GSD EIA Lyme kits is shown below.
