Hair Follicle Drug Testing - Perryman, MD

What it is, How it works

Hair testing is now recognized as an effective method for detecting alcohol and drug consumption. Hair strands capture biomarkers within their fibers as they grow, offering a prolonged historical record of alcohol and drug presence. When extracted near the scalp, hair can reveal usage patterns extending up to around three months. Hair sampling is straightforward, resistant to tampering, and convenient for transportation.

A 1.5-inch cluster of approximately 200 hair strands (comparable to a #2 pencil’s thickness) from the scalp yields 100mg, ideal for both screening and confirming results. For EtG testing, add-ons, or tests exceeding 10 panels, collecting 150mg of the sample is advised. It's recommended to measure the sample with a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be obtained. References to head hair specifically imply scalp hair, while body hair refers to all other types (e.g., facial, axillary).

Process Overview

The drug testing cycle in the lab consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample enters the lab's system for initial processing. This step ensures the sample was securely sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and includes completing any data entry not managed by an electronic chain of custody.

Screening offers an immediate assessment for potential drug usage. Though cost-efficient for eliminating drug consumption in most samples, a positive result in Screening mandates confirmation for legal acceptance. Samples flagged as likely positive require further verification.

If a sample appears positive in the Screening phase, more strands are extracted from the original collection for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or saliva), highlighting the complexity of hair drug testing.

Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Samples deemed potentially positive are pre-washed if necessary before confirmation. The laboratory thoroughly reviews the entire process—from Accessioning to Confirmation—under the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use for up to 90 days, unlike the shorter timeframe of urine tests.
• Hard to falsify: Cheating a hair drug test is extremely challenging, enhancing result reliability.
• Reflects historical patterns: It charts drug use over time, rather than just recent consumption.

Limitations:

• Cannot pinpoint recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing typically incurs higher costs than alternative methods.
• Result variability: Factors such as hair pigment and personal growth rates may influence drug metabolite levels in hair.

Note: Often misnamed as "hair follicle tests", the analysis focuses on the hair strand itself rather than the follicle beneath the scalp.
