A longer lookback period
Hair testing can help an employer or program assess a longer period of drug exposure than a typical urine test. The window depends on specimen length, the laboratory method and the substance.

What Test First provides
Professional service with clear documentation
Hair and nail options
Our published five-panel hair/nail test is $175. These are distinct specimen types: confirm which one your requesting organization accepts before paying for a collection.
Use the requested panel
A five-panel order is not interchangeable with every expanded panel. Tell us if your paperwork names a laboratory, test code, required drug or chain-of-custody procedure.
What to expect
A straightforward testing process
- 01
Check the written order
Bring the requesting organization’s instructions, deadline and authorized result recipient. If testing is for personal information, tell staff before collection.
- 02
Prepare for collection
Bring government-issued photo ID. Staff will review hair availability and the laboratory collection requirements before collecting the specimen.
- 03
Confirm result delivery
Ask about the current laboratory turnaround and authorized delivery method. Collection completion does not mean the final laboratory report is immediately available.
Common questions
Answers before you visit
Does a hair test show the last 90 days?
About 1.5 inches of head hair is commonly used to assess approximately 90 days. This is an estimate, not a precise calendar of use; specimen type and laboratory requirements affect the window.
Can I use a hair test instead of a DOT drug test?
No. A hair test is not a substitute for a required DOT drug test. Bring the DOT order so the correct regulated collection can be arranged.
Is hair testing suitable immediately after an accident?
Hair is not the right specimen for detecting very recent use immediately after an incident. The employer must identify the required post-accident test; call for collection arrangements.
What if I do not have enough head hair?
Call before visiting. Staff can check the laboratory’s requirements and whether an alternative specimen is acceptable to the organization ordering your test.
