12-Month Hair Drug Test: What It Screens For | AMH Nationwide
12-Month Hair Drug Test What It Screens and How Panel Size Affects Detection
The 12-month hair drug test what it screens includes a range of substances depending on the panel size, typically covering common drugs like marijuana, cocaine, opiates, and amphetamines. Panel size affects which drugs are detected over the 12-month period. Call (877) 731-6362 to arrange your test.
What substances does a 12-month hair drug test screen for?
A 12-month hair drug test what it screens includes detection of drug metabolites deposited in hair strands over a year. The standard panels typically include marijuana (THC), cocaine, opiates (such as morphine and codeine), amphetamines (including methamphetamine and MDMA), and PCP.
Extended panels may also test for benzodiazepines, barbiturates, synthetic cannabinoids, and other substances depending on the specific panel requested. The test identifies drug use spanning the past 12 months by analyzing hair segments.
How does panel size affect what the 12-month hair drug test screens?
The 12-month hair drug test what it screens varies by panel size, which determines the number and type of substances detected. Basic panels cover common drugs including marijuana, cocaine, opiates, and amphetamines.
Expanded panels add substances such as benzodiazepines, barbiturates, methadone, synthetic opioids, and some designer drugs. Larger panels increase the scope of detection but may affect cost and processing time.
How is the 12-month hair drug test collected and processed?
The 12-month hair drug test involves collecting a small hair sample, typically from the scalp, which reflects drug use over the past year. AMH routes collections through five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox.
After collection, the sample undergoes laboratory analysis to identify drug metabolites embedded in the hair shaft. All non-negative results are reviewed by a certified Medical Review Officer as part of standard processing.
Who typically requests a 12-month hair drug test and why?
Employers, legal entities, and probation officers often request a 12-month hair drug test for comprehensive drug use history verification. It is useful for assessing long-term substance use patterns rather than recent use.
This test is also used in situations where urine or oral fluid tests are insufficient due to their shorter detection windows. Hair testing is non-DOT and intended for non-safety-sensitive roles due to federal regulations.

What are the limitations of the 12-month hair drug test what it screens?
The 12-month hair drug test does not detect very recent drug use within the past week since hair takes time to grow above the scalp. It also may not detect drug use if hair samples are too short or chemically treated.
Some substances are less reliably detected in hair, and panel size limits which drugs are screened. The test is not federally certified for DOT-regulated safety-sensitive testing which requires urine testing under 49 CFR Part 40.

Common Questions
The test detects drug metabolites in hair segments that represent drug use over the previous 12 months, providing a long-term view of substance use.
Detection depends on the panel size. Basic panels test common drugs, while expanded panels include additional substances like benzodiazepines and synthetic cannabinoids.
No. DOT-regulated safety-sensitive testing requires federally certified urine testing under 49 CFR Part 40. Hair testing is for non-DOT roles.
A small hair sample is cut close to the scalp, usually from the crown of the head. The sample reflects drug use over time as hair grows.
Chemical treatments, very short hair, or infrequent hair growth can affect detection. Also, very recent drug use within a week may not be detected.
