Facilities (IITFs) Which Meet Minimum Standards to Engage in Urine and Oral Fluid Drug 

Testing for Federal Agencies (18 UNITED STATES LABS and 2 CANADIAN LABS and 1 

CANADIAN IITF, for a total of 20 HHS Certified Labs and 1 IITF). 

 

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

laboratories and IITFs currently certified to meet the standards of the Mandatory Guidelines for 

Federal Workplace Drug Testing Programs (Mandatory Guidelines) using Urine or Oral Fluid. 

 

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 

(73 FR 71858); December 10, 2008 (73 FR 75122); April 30, 2010 (75 FR 22809); January 23, 

2017 (82 FR 7920); and on October 12, 2023 (88 FR 70768) with an effective date of February 

1, 2024. 

 

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

October 25, 2019 (84 FR 57554), and subsequently revised in the Federal Register on October 

12, 2023 (88 FR 70814) with an effective date of October 10, 2023.

 

A notice listing all currently certified laboratories and IITFs 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.
