What is the likelihood that a testing device is defective?

Unexpected test results or failure to obtain test results is the result of user error 98% of the time.

This because of:

  • Failure to follow instructions
  • Inadequate sampling
  • Device contamination
  • Failure to use a timer or other user related factor.

The stringent quality control checks and required random sampling methods mandated by the governmental regulatory authorities during the production process of these devices make the likelihood of receiving a defective test device extremely remote.
