Hair Follicle Drug Test: Results Timeline | AMH Nationwide
Hair Follicle Drug Test Results Timeline for Accurate and Timely Reporting
Hair follicle drug test results timeline typically ranges from 5 to 7 business days after sample collection. Non-negative results trigger a confirmation process reviewed by a certified Medical Review Officer, which may extend the timeline. Factors such as lab volume and shipping can also cause delays. Call (877) 731-6362 for more information.
What is the typical turnaround time for hair follicle drug test results?
The typical turnaround time for hair follicle drug test results is 5 to 7 business days after the sample is collected at a designated collection site.
This timeline includes routing the sample through one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox.
The labs perform initial testing, and if the screen is non-negative, additional steps are required which can extend the overall timeline.
What happens if hair follicle drug test results are non-negative?
If hair follicle drug test results are non-negative, the sample undergoes a confirmation test using a more specific method such as gas chromatography-mass spectrometry (GC-MS).
This confirmation step is standard and ensures the accuracy of the findings before final reporting.
A certified Medical Review Officer (MRO) reviews all non-negative results to interpret and verify them. This review process adds 2 to 3 additional business days to the overall timeline.
What factors can delay hair follicle drug test results?
Several factors can delay hair follicle drug test results beyond the typical 5 to 7 business days.
High lab volume during peak periods can slow processing times.
Shipping delays between the collection site and the lab network may add extra days.
Incomplete or improperly collected samples require recollection, which extends the timeline.
