Current List of HHS-Certified Laboratories and Instrumented Initial Testing Facilities 

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

Federal Agencies 

AGENCY: Substance Abuse and Mental Health Services Administration, HHS. 

ACTION: Notice. 

SUMMARY: The Department of Health and Human Services (HHS) notifies Federal agencies 

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

the standards of the Mandatory Guidelines for Federal Workplace Drug Testing Programs 

(Mandatory Guidelines) using Urine and the laboratories currently certified to meet the standards 

of the Mandatory Guidelines using Oral Fluid. 

FOR FURTHER INFORMATION CONTACT: Anastasia Flanagan, Division of Workplace 

Programs, SAMHSA/CSAP, 5600 Fishers Lane, Room 16N06B, Rockville, Maryland 20857; 

240-276-2600 (voice); Anastasia.Flanagan@samhsa.hhs.gov (email). 

SUPPLEMENTARY INFORMATION: The Department of Health and Human Services 

(HHS) publishes a notice listing all HHS-certified laboratories and Instrumented Initial Testing 

Facilities (IITFs) in the Federal Register during the first week of each month, in accordance with 

Section 9.19 of the Mandatory Guidelines for Federal Workplace Drug Testing Programs 

(Mandatory Guidelines) using Urine and Section 9.17 of the Mandatory Guidelines using Oral 

Fluid. If any laboratory or IITF certification is suspended or revoked, the laboratory or IITF will 

be omitted from subsequent lists until such time as it is restored to full certification under the 

Mandatory Guidelines. 
If any laboratory or IITF has withdrawn from the HHS National Laboratory Certification 

Program (NLCP) during the past month, it will be listed at the end and will be omitted from the 

monthly listing thereafter. 

 This notice is also available on the Internet at https://www.samhsa.gov/workplace/drugtesting-resources/certified-lab-list. 

HHS separately notifies Federal agencies of the laboratories and IITFs currently certified 

to meet the standards of the Mandatory Guidelines using Urine and of the laboratories currently 

certified to meet the standards of the Mandatory Guidelines using 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). 

 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, and subsequently 

revised in the Federal Register on October 12, 2023 (88 FR 70814). 

The Mandatory Guidelines were initially developed in accordance with Executive Order 

12564 and section 503 of Pub. L. 100-71 and allowed urine drug testing only. The Mandatory 

Guidelines using Urine have since been revised, and new Mandatory Guidelines allowing for 

oral fluid drug testing have been published. The Mandatory Guidelines require strict standards 

that laboratories and IITFs must meet in order to conduct drug and specimen validity tests on 

specimens for Federal agencies. HHS does not allow IITFs to conduct oral fluid testing. 

To become certified, an applicant laboratory or IITF must undergo three rounds of 

performance testing plus an on-site inspection. To maintain that certification, a laboratory or 

IITF must participate in a quarterly performance testing program plus undergo periodic, on-site 

inspections. 
 Laboratories and IITFs in the applicant stage of certification are not to be considered as 

meeting the minimum requirements described in the HHS Mandatory Guidelines using Urine 

and/or Oral Fluid. An HHS-certified laboratory or IITF must have its letter of certification from 

HHS/SAMHSA (formerly: HHS/NIDA), which attests that the test facility has met minimum 

standards. HHS does not allow IITFs to conduct oral fluid testing. 

HHS-Certified Laboratories Approved to Conduct Oral Fluid Drug Testing: 

In accordance with the Mandatory Guidelines using Oral Fluid effective October 10, 

2023 (88 FR 70814), the following HHS-certified laboratories meet the minimum standards to 

conduct drug and specimen validity tests on oral fluid specimens: 

At this time, there are no laboratories certified to conduct drug and specimen validity tests on 

oral fluid specimens.

________________ 

*The Standards Council of Canada (SCC) voted to end its Laboratory Accreditation Program for 

Substance Abuse (LAPSA) effective May 12, 1998. Laboratories certified through that program 

were accredited to conduct forensic urine drug testing as required by U.S. Department of 

Transportation (DOT) regulations. As of that date, the certification of those accredited Canadian 

laboratories continued under DOT authority. The responsibility for conducting quarterly 

performance testing plus periodic on-site inspections of those LAPSA-accredited laboratories 

was transferred to the U.S. HHS, with the HHS’ NLCP contractor continuing to have an active 

role in the performance testing and laboratory inspection processes. Other Canadian laboratories 
wishing to be considered for the NLCP may apply directly to the NLCP contractor just as U.S. 

laboratories do. 

 Upon finding a Canadian laboratory to be qualified, HHS will recommend that DOT 

certify the laboratory as meeting the minimum standards of the current Mandatory Guidelines 

published in the Federal Register. After receiving DOT certification, the laboratory will be 

included in the monthly list of HHS-certified laboratories and participate in the NLCP 

certification maintenance program. DOT established this process in July 1996 (61 FR 37015) to 

allow foreign laboratories to participate in the DOT drug testing program.
