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 using

Urine or Oral Fluid (Mandatory Guidelines).  

The Mandatory Guidelines using Urine 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

The Mandatory Guidelines using Oral Fluid were first published in the Federal Register on

October 25, 2019 (84 FR 57554) with an effective date of January 1, 2020.  

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.
