Three objective systems are used to track a variety of treatment and assay adherence.

The MDILog and Doser are used to track adherence of inhaled drugs (metered dose inhalers).

The MEMs Cap is used to track adherence with oral medication (pills). It can also be used to track at-home sample collection such as cortisol samples.

The adherence tracking devices are provided to the investigator with technical support, including set-up, data downloading, data verification, and delivery of complete data sets.
