INTRODUCTION During the past two decades, there has been increasing interest in using oral fluid (OF) as a testing specimen. A variety of techniques have been used to collect OF. Historically, the effects of the collection technique on testing and the test results have largely been ignored. The purpose of the following article is to:


1. Provide the DATIA reader with insight into the effects of collection methods and devices on OF drug test results; and


2. Help the reader discriminate between potentially effective and ineffective devices.
