ParaDNA® Screening Test

The ParaDNA Screening Test is an effective tool for improving sample screening/triage by increasing submissions success rates, and reducing the requirement for costly lab processing of needless samples. It takes just 75 minutes; screen crime scene stains/swabs to gain a rapid understanding if subsequent DNA extraction, quantification, amplification and detection will deliver a useable result.

  • Reduce forensic spend while targeting resources on most probative samples
  • Eliminate backlog issues - develop a more confident and targeted submissions policy 
  • Increase effective submissions of touch DNA samples (e.g. triage property crime)
  • Single-use ParaDNA Sample Collector can be used directly on blood, saliva, semen and cellular  (inc. touch) samples
  • Minimal training requirement to get up and running - use in the lab or at scene to gain simple easy-to-interpret results
  • No laboratory preparation/extraction steps required – sampled items are not consumed and can still be sent for further forensic processing 
  • Uses patented HyBeacon probe technology to target human specific STRs

ParaDNA Screening Test results output

  • Green: The system has detected the presence of Human DNA. If enough DNA is detected, the ParaDNA screening software also indicates whether the DNA obtained is of male or female origin
  • Red: The system has failed to detect any presence of Human DNA

Sampling procedure

DNA is recovered using LGC’s patented ParaDNA Sample Collector. Collectors are provided individually packaged and treated to ensure they are DNA free, and are used to sample crime stains directly, or to indirectly sample swabbed material. The ParaDNA Sample Collector design allows the user to accomplish sampling with four ‘nibs’ that are combined into one. Once sampling is complete a collar on the collector is pulled back to separate the nibs, which are then loaded into a ParaDNA Screening Test plate. This creates a sealed system, which once placed on a ParaDNA Instrument, delivers DNA amplification, detection and analysis in just 75 minutes.
