The Department of Health and Human Services (HHS) notifies federal agencies of the 

laboratories and Instrumented Initial Testing Facilities (IITF) currently certified to meet the 

standards of the Mandatory Guidelines for Federal Workplace Drug Testing Programs 

(Mandatory Guidelines). The Mandatory Guidelines were first published in the Federal Register 

on April 11, 1988 (53 FR 11970), and subsequently revised in the Federal Register on June 9, 

1994 (59 FR 29908); September 30, 

1997 (62 FR 51118); April 13, 2004 (69 FR 19644); November 25, 2008 (73 FR 71858); 

December 

10, 2008 (73 FR 75122); April 30, 2010 (75 FR 22809); and on January 23, 2017 (82 FR 7920) 

A notice listing all currently certified Laboratories and Instrumented Initial Testing Facilities 

(IITF) is published in the Federal Register during the first week of each month. If any Laboratory 

or IITFs’ certification is suspended or revoked, the Laboratory/IITF will be omitted from 

subsequent lists until such time as it is restored to full certification under the Mandatory 

Guidelines.
