Title: Current List of Laboratories and Instrumented Initial Testing Facilities (IITF) Which Meet 

Minimum Standards To Engage in Urine Drug Testing for Federal Agencies

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.
