Title: State List of Current HHS‐Certified Laboratories and Instrumented Initial Testing Facilities

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

Federal Agencies (21 UNITED STATES LABS and 1 CANADIAN LAB and 1 CANADIAN 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); and on January

23, 2017 (82 FR 7920).  

  

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 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.
