Hair Follicle Drug Testing - Tunis Mills, MD

What it is, How it works

Hair assessments have gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug use by capturing biomarkers within the fibers of the hair as it grows. When clipped near the scalp, hair can reveal a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A hair sample measuring 1.5 inches, approximately 200 strands or the thickness of a #2 pencil, closest to the scalp will yield 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, and panels exceeding 10, a 150mg sample is advisable. It’s suggested to measure the sample with a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be used. The term "head hair" refers solely to scalp hair, while "body hair" includes all other types, such as facial or axillary.

Process Overview

The laboratory procedure for processing a drug test outcome includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial handling of a sample through a lab's system. This step confirms that the sample was appropriately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any further data tasks not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drug presence. While cost-effective for excluding drug intake in most samples, a positive screen must be validated for legal consideration. Samples with presumed positive results during Screening necessitate further confirmation.

Should a sample show a presumed positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. At this stage, drug substances are extracted from hair concentrations lower than other approaches (such as urine or oral fluids), making hair drug testing a particularly challenging technique.

Any positive result is verified using GC/MS, GC/MS/MS or LC/MS/MS. Any samples with a presumed positive outcome are cleansed as required before confirmation. The laboratory sequence from Accessioning to Confirmation is regulated by both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug intake for up to 90 days, unlike urine tests which have a narrower detection range.
• Low probability of manipulation: Cheating a hair drug test is particularly challenging, enhancing result accuracy.
• Provides usage trends: It offers a chronological record of drug use over time, rather than just recent use.

Limitations:

• No detection of recent use: Drugs need about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other drug analysis methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests," these tests actually analyze the hair shaft, not the follicle beneath the scalp.
