Pending FDA Clearance.

Introducing the next evolution in syphilis testing which complies with the CDC recommended traditional algorithm for nontreponemal syphilis screening.1 Laboratories can now automate nontreponemal testing and drive significant operational efficiencies while minimizing false-positive results.

The USA made ASI Evolution is a fully automated syphilis analyzer.  Laboratories will benefit from ASI Evolution substantially lower capital expenditure, and lower cost per test. The user friendly, system is capable of performing more than 190 tests per hour in a full walk-away platform. The analyzer does not require custom designed and expensive consumables.  This Value Proposition will allow laboratories using the ASI Evolution to enjoy important savings in both labor and efficiency.

Evaluation of the ASI Evolution™ Automated Syphilis Analyzer

A total of 3217 specimens were evaluated to determine reactivity. Of the 3217 specimens, 1093 were reactive and 2124 specimens were nonreactive visually. The ASI Evolution identified 1080 of the 1093 reactive specimens as reactive and 2121 of the 2124 nonreactive specimens as nonreactive.  A sensitivity of 98.8% and a specificity of 99.8% were determined.

The reactive samples ranged in reactivity from minimal 1:1 titers to 1:64 titers.

The Nontreponemal Advantage

  • A 2015 study by the CDC determined that nontreponemal tests can detect infection up to 14 days earlier than treponemal tests.
  • CDC recommended algorithm
  • Preserve valuable blood resources
  • Reduce confusion among clinicians
