Validation of a new method to measure hydrogen peroxide in exhaled breath condensate

We tested a new commercial device (Ecocheck™), developed to offer a less time-consuming method to measure H2O2. We validated this new method according the NCCLS EP10-A2 protocol. The validation shows that the imprecision in the low range is high (28.4%) and declines with higher concentrations of H2O2 (up to 6.6%). The Ecocheck™ is “an easy to use” measuring device for routine measurements getting quick results without the need for skilled technicians to determine H2O2 concentrations.
