High Accuracy Nonanimal Eye Test

The NEW version of OptiSafe is called OS2. 
Like OptiSafe, OS2 also has a zero FN rate; however, OS2 also has a low FP rate and accuracy over 90%.

  • Now available as a service

The New Formulation has significantly reduced the FP rate without increasing the FN rate:
Based on the total number of chemicals tested from a previous OptiSafe validation study and an expanded number of ocular corrosives and surfactants for the NC versus other irritant classes (GHS categories 2B/A and 1), the FP rate was 19.1% (9/47), the FN rate was 0.0% (0/86), and the accuracy was 93.2% (124/133).
