Hair Follicle Drug Testing - Seneca, MD

What it is, How it works

Hair analysis is recognized as a potent method for identifying alcohol and drug consumption. The hair acts as a historical record of substance use by incorporating biomarkers within its growing fibers. If hair is taken from near the scalp, it offers a detection window of up to roughly three months for alcohol and other drugs. Collecting hair is straightforward, and although somewhat challenging to tamper with, it is convenient to send.

A 1.5-inch section consisting of approximately 200 hair strands (roughly matching a #2 pencil thickness) taken nearest to the scalp will yield 100mg, an optimal sample for both screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not present, an equivalent portion of body hair can be utilized. The term head hair pertains solely to scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of hair drug tests involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning step captures the initial handling of a sample within a lab's system. This stage ensures that the sample was securely sealed and correctly transported, a random LAN (Laboratory Accessioning Number) is allocated, and any additional data input not covered by an electronic chain of custody is completed.

Screening entails a preliminary swift test for illicit drugs. Although Screening is economical for ruling out drug involvement in most samples, a positive screen must be verified for it to be valid in legal contexts. Samples with a presumptive positive result in Screening necessitate a further confirmation.

When a sample shows a presumptive positive at the Screening phase, additional hair from the original sample is prepared for Extraction. During this phase, drug substances are extracted from the hair at much lower levels than alternative methods (e.g., urine or oral fluids), which is why hair drug testing is among the most challenging processes.

Confirmation of any positive screen results is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing a presumptive positive are cleansed before confirmation if needed. The full lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: It is particularly challenging to alter a hair drug test, enhancing the precision of findings.
• Displays usage pattern: It can illustrate a history of drug use over time, rather than merely indicating recent consumption.

Limitations:

• Cannot pinpoint recent consumption: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other drug test methods.
• Result variations: Factors like hair color and individual hair growth can influence the levels of drug metabolites in the hair.

Note: Although often labeled as "hair follicle tests", the analysis targets the hair strand itself and not the follicle beneath the scalp.
