FDA Cleared For Diagnostic, Blood Donor and Cadaveric Tissue Screening

For over 37 years Arlington Scientific has been a pioneer in delivering new products and technologies to meet the growing demands of clinical diagnostics, blood donor and cadaveric tissue laboratories worldwide. The ASI Evolution® Automated Syphilis Analyzer was developed using the traditional syphilis algorithm to address the need for an automated nontreponemal syphilis platform.

The ASI Evolution® can process and analyze up to 190 samples per hour. One technician can easily run three ASI Evolutions simultaneously, with the ability to perform over 4,000 tests in an eight-hour shift.

Reduce Labor

The ASI Evolution reduces the amount of hands on time required to run an RPR test, freeing up valuable lab resources.

Improve Efficiency

  • Run 190  tests per hour per analyzer
  • Single operator can run multiple ASI Evolutions simultaneously
  • Skilled laboratorian available for other protocols
  • Titers from 1:1 to 1:2048

Better Quality

  • CDC recommended testing
  • Your Syphilis Authority
  • Accurate and reproducible results
  • Data Management (Analyze, Archive, Retrieve)

Lower Costs

  • Reduced labor expense
  • Lowest cost syphilis testing reagent
  • Minimal consumables required
  • Lower total healthcare cost

Advantages of Traditional Nontreponemal RPR Testing

“The CDC continues to recommend the traditional screening algorithm using a nontreponemal test (e.g., RPR or VDRL), with reactive nontreponemal tests confirmed by treponemal testing.”*

Early Detection

A 2015 CDC study determined that nontreponemal tests can detect infection up to 14 days earlier than treponemal tests.

Why Nontreponemal?
The CDC recommends it, doctors prefer it, a majority of labs use it, costs less, better quality, fewer false-positives

The ASI Evolution® is the world’s first and only fully-automated system for nontreponemal RPR Syphilis testing for diagnostic, blood donor and cadaveric tissue screening. Simply load your reagents and samples, then walk-away. The Evolution automates the processing, analysis, reporting and archival of results for RPR screens.
