Hair Testing

Lab-based hair analysis offers a longer detection window than urine — a screening option for pre-employment and high-assurance programs.

Where hair testing fits

  • Lab-based hair analysis
  • Pre-employment screening
  • High-assurance screening

Add this to your program

Discuss the test method, screening purpose and other services your program needs.

Discuss suitability before choosing hair

The operational Diagnostics site lists hair testing alongside urine and oral-fluid options. A method should be chosen for the actual screening purpose, collection setting and program requirements, rather than because one format appears more extensive.

Ask about collection arrangements, laboratory analysis, result review and the limits of the method for your use case. A specialist can explain how hair testing fits alongside the rest of the employer’s testing program.

What to confirm

  • Why your organization is considering hair testing
  • Where and by whom specimens would be collected
  • How results and any follow-up would be handled
A specialist. A shared relationship.

Scope the testing path with the team.

Bring the testing purpose, locations, current process and the responsibilities your team needs supported. Your inquiry is saved for Noble staff follow-up; no external provider receives an order through this site.
