Also known as Home, Personal Knowledge and PK, an informational test can be conducted privately, even anonymously, if you wish. However there are usage restrictions imposed by the labs, just as with discount airline seats. In particular, the labs do not offer a notarized report option for use in court. Nevertheless, just as with discount airline seats, you receive the same safety and timeliness while paying less than half that of a full-fare customer.
