Sanitizing efficacy is total organism count. Hand sanitizers are regulated by the FDA and tested in vivo using ASTM 1174 (Health Care Personnel Handwash / HCPHW test) and ASTM 2755. E1174 tests for Serratia marcescens or Escherichia coli. E2755 tests for S. marcescens or Staphylococcus aureus. ASTM E1174-21 includes a precision and accuracy statement.
