Purpose: This Addendum documents the employee's consent to drug and alcohol testing as a condition of employment or continued employment. The undersigned acknowledges that the employer may require testing under the circumstances set forth below and that compliance is mandatory where required by law or company policy.

Types of testing authorized (select all that apply):
              

Collection methods to which I consent:
        

Standard test panel includes detection for the following substances (select applicable):
        
        

Medical Review Officer (MRO) and Prescription Disclosure: I authorize the release of confirmed positive test results to a licensed Medical Review Officer for independent review. I understand I must disclose to the MRO any prescription or over-the-counter medications that could affect test results prior to or at the time of testing.

Chain of custody and split sample: Specimen collection and handling will follow established chain of custody procedures. When permitted, I may request a split specimen and the procedures and timelines for such requests are those used by the testing laboratory and MRO.

Consequences of positive test, refusal, or adulteration: A verified positive test, a confirmed adulterated or substituted specimen, or refusal to submit to a required test may result in withdrawal of any offer of employment or disciplinary action up to and including termination consistent with company policy and applicable law.

Cost and testing location: The employer will ordinarily pay for required tests administered at employer-designated facilities. If I choose additional or voluntary testing beyond employer requirements, I may be responsible for those costs unless otherwise specified.

Confidentiality and disclosure: Testing results and related medical information will be maintained in a secure file and disclosed only to individuals with a business need to know, such as human resources, safety management, the MRO, and as required by law or regulation.

Special status: If this position is safety-sensitive or subject to commercial driver or other regulated testing requirements, additional testing protocols and reporting requirements may apply; I have been advised to review those requirements with the employer prior to testing.

Authorizations and Certifications

Applicant Certification: I certify that all information provided on this Addendum is true and complete to the best of my knowledge. I understand that any material misrepresentation or omission may subject me to disciplinary action, including removal of an offer or termination of employment.

Authorization to Test and Release Results: I hereby voluntarily consent to the collection and testing of biological specimens as described above. I authorize the testing laboratory and Medical Review Officer to release test results and related information to the employer, the employer's testing administrator, and to those designated by employer policy for purposes related to employment, safety, and compliance.

Authorization to Contact Prior Employers and Background Screening: I authorize the employer to contact prior employers and listed references for purposes of verifying employment history and job-related information, and to obtain background screening reports where permitted by law. I further authorize any prior employer or reference to provide information requested and release them from liability for furnishing such information.

At-Will Employment: Nothing contained in this Addendum creates a contract of employment for any specified duration. Employment remains at-will unless otherwise provided in a separate written agreement signed by an authorized representative of the employer.

Equal Opportunity: The employer is an equal opportunity employer. Decisions related to testing, discipline, or employment are made without regard to protected characteristics, consistent with applicable law.

By signing below I acknowledge receipt of this Drug Screen Addendum, that I have had the opportunity to ask questions regarding the testing procedures and consequences, and that I understand the terms set forth herein.

What the HR Drug Screen Addendum Is and when it applies

The HR Drug Screen Addendum is a short, attachable document that supplements an offer letter or employment agreement by documenting an employee's consent to pre-employment or post-offer drug testing, the types of tests to be used, and the handling of results. It clarifies the chain-of-custody process, identifies the testing laboratory or third-party clinic, and records the timeframe for testing and result disclosure. Employers use the addendum to show informed consent, to align testing with company policy and applicable law, and to create an auditable record of the testing arrangement and authorization.

Why an addendum improves HR clarity and compliance

A clear Drug Screen Addendum documents consent, test scope, result handling, and contractual effect, reducing disputes and supporting defensible decision-making in safety-sensitive roles.

Why an addendum improves HR clarity and compliance

Who commonly completes or receives this addendum

The addendum is used by employers, staffing agencies, and occupational health providers when a drug test is required as part of pre-employment screening or ongoing monitoring.

  • HR managers and recruiters responsible for onboarding and policy enforcement in hiring processes.
  • Occupational health clinics and third-party testing vendors that administer tests and report results.
  • Supervisors or safety officers in regulated or safety-sensitive functions (transport, construction, utilities).

Its purpose is administrative and legal: to record consent, identify the test and vendor, and specify who receives results.

Primary signer roles and what they do

HR Manager

An HR Manager signs or executes the addendum on behalf of the employer or sends it for signature, verifies that the testing type matches company policy, and ensures the document is retained in the personnel file consistent with record retention rules.

Occupational Health Nurse

An Occupational Health Nurse or clinic representative completes testing logistics, confirms chain-of-custody steps, documents specimen collection details, and may sign to confirm that testing occurred according to stated procedures and consent.

Essential elements every HR Drug Screen Addendum should include

A professional addendum is concise but complete: identify parties, describe the test, explain consent and data handling, provide chain-of-custody details, and include signature and date fields.

Parties

Clearly identify the employer and the individual by full legal name and include employer contact details and the testing vendor or clinic name to avoid ambiguity about responsibilities.

Purpose

State whether the test is pre-employment, random, reasonable suspicion, post-incident, or return-to-duty, and link to the relevant company policy or handbook section when possible.

Test Types

List the test sample(s) (urine, saliva, hair, blood), substances screened, and whether confirmatory testing (e.g., GC/MS) will be used for presumptive positives.

Consent & Authorization

Include an explicit consent clause authorizing specimen collection, testing, result release to designated parties, and acknowledgment of consequences for a positive result.

Chain of Custody

Describe sample handling, labeling, transport, laboratory accreditation expectations, and that a Medical Review Officer (MRO) will review positives before employer action.

Signature Block

Provide lines for the applicant/employee signature, printed name, date, and a signer role for the clinic or HR representative to confirm collection or receipt.

Required data fields and short entry notes

Employee Name: Full legal name
Date of Birth: MM/DD/YYYY
Identifier: Last 4 of SSN or employee ID
Test Type: Urine, saliva, hair, etc.
Test Date: MM/DD/YYYY
Consent Checkbox: Employee initials or signature

Step-by-step: completing the HR Drug Screen Addendum

Follow these four steps to complete the addendum correctly and create a reliable record for HR and the testing vendor.

  • 01
    Prepare the form: Attach to the offer or policy and confirm the correct testing type.
  • 02
    Provide instructions: Give the employee testing location, arrival window, and ID requirements.
  • 03
    Collect consent: Employee signs and dates; clinic documents specimen collection.
  • 04
    Record results: MRO or lab reports results to designated HR contact and file documentation.

Typical routing: where the addendum goes after signing

Understand routing so results reach only authorized reviewers and records are retained correctly.

  • To the Clinic: Employee gives signed addendum to the testing clinic at collection.
  • Lab Processing: Lab performs the specified tests and forwards presumptive positives to the MRO.
  • MRO Review: MRO verifies medical explanations and confirms final positive or negative results.
  • HR Receipt: MRO or lab transmits the final report to the designated HR contact in accordance with consent.

Configuring an online signing workflow for the addendum

Set up a simple eSignature workflow to route the addendum from HR to the employee and then to the testing vendor.

Field Configuration
Authentication Email link with optional SMS code for signer verification
Signature Type Allow typed or drawn e-signature; capture timestamp
Conditional Fields Show confirmatory-test fields only for positive screens
Integrations Connect to HRIS or EHS systems for automated filing

Technical considerations for eSubmission and eSignature

Choose an eSignature platform that supports audit trails, conditional fields, and secure delivery to third parties.

  • Audit Trail: Capture IP, timestamp, and action logs
  • File Formats: PDF and DOCX supported for export and archival
  • Integrations: Connects with HRIS, Google Workspace, and cloud storage

Common timeframes to include or expect

Timelines help set expectations for testing, reporting, and next steps after results are available.

Offer-to-Test Window:

24–72 hours from offer acceptance in many hiring processes

Specimen Collection Time:

Document exact date and time of collection on the addendum

MRO Review Period:

Typically 2–5 business days for medical review and confirmation

Result Reporting:

Final results often delivered within 24–72 hours of collection

Retest/Confirm Window:

Employee may request confirmatory testing within specific policy timeframes

Common mistakes to avoid when preparing the addendum

  • Leaving the test panel unspecified, causing lab or MRO confusion and delays in result interpretation.
  • Failing to record collection time or collector identity, which can break chain-of-custody and invalidate a sample.
  • Collecting excessive personal data (full SSN) in the personnel file instead of using a minimal identifier.
  • Not documenting who is authorized to receive results, which can lead to privacy violations or unauthorized disclosures.

Principal legal and operational risks from incorrect or missing addenda

Employment Claims: Wrongful termination or discrimination allegations
HIPAA Violations: Unlawful PHI disclosure risk if privacy controls fail
Chain Break: Sample invalidation and lost evidentiary value
Regulatory Fines: Penalties for noncompliance in regulated sectors
Hiring Delays: Operational costs from delayed start dates
Reputational Harm: Damage from mishandled medical information

Practical tips for accurate and efficient completion

Follow these best practices to minimize delays, protect privacy, and ensure defensible testing procedures.

Use minimal personal identifiers
Record only necessary identifiers (last 4 of SSN or employee ID) in personnel files and keep full SSN or sensitive data in a secure, limited-access system.
Document chain-of-custody fully
Capture collector name, time, and transport details on the addendum or chain-of-custody form to preserve evidentiary value and lab acceptance.
Specify result recipients
List exact HR or medical review officer recipients to prevent unauthorized disclosure and to comply with privacy requirements.
Use conditional fields online
Show confirmatory or additional consent fields only when a presumptive positive occurs to streamline initial collection and reduce signer confusion.
