  • Uses existing extraction methods
  • 2 step protocol – resuspend, add extract
  • Only requires isothermal reader
  • Works with existing PCR equipment
  • Individual or pooled serum samples for maximum flexibility
  • 2-8°C storage
  • Simple molecular addition to your diagnostic portfolio


Accuracy – 99.7%
Extraction Control Accuracy – 98.9%
Analytical Sensitivity – 5×10² copies/µl
Positive Predictive Value (PVV) Proportion of those with a POSITIVE test that have Disease – 100.0%
Negative Predictive Value (NPV) Proportion of those with a NEGATIVE test that do not have Disease – 99.4%
Cohen’s Kappa (κ) – 0.994 ‘Near perfect agreement’
