Recently, hair follicle drug testing has become a more prominent method for substance screening. Courts, employers, and substance abuse experts are opting for hair tests over urine tests. This choice is popular among employers with zero-tolerance policies and courts for probation cases. Hair tests offer a longer detection window, often up to 90 days, and are difficult to tamper with. However, for identifying drug use in the past 5 days, urine tests remain more accurate.

Hair tests are now recognized as an effective method for identifying drug and alcohol consumption. Hair strands preserve a prolonged record of substance intake by encapsulating biomarkers within the hair as it grows. If hair is gathered near the scalp, it can offer an observation period of roughly three months for detecting alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
A 1.5-inch snippet of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp amounts to 100mg, which is the perfect test sample for both screening and confirmation procedures. For EtG, additional tests, or tests exceeding 10 panels, a larger sample of 150mg is advised. We suggest measuring the hair on a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair is acceptable. Head hair specifically refers to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
There are four critical phases in the lab process of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first processed within a lab's system. This phase ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.
The Screening phase offers an initial quick assessment for substance abuse. Although Screening is a budget-friendly approach to eliminate drug use across most samples, positive results from this stage must be verified for legal acceptance. Any samples with a presumptive positive outcome in Screening necessitate subsequent confirmation.
If the Screening phase yields a presumptive positive result, additional hair is extracted from the original sample to prepare for Extraction. In Extraction, drugs are extracted from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is considered the most challenging method to conduct.
Positive Screening results are validated using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives undergo washing before confirmation if needed. The complete lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation, along with ISO / IEC 17025 accreditation standards.
