Hair Follicle Drug Testing - Ledgeview, WI

What it is, How it works

Hair analysis is now widely recognized as a significant method for identifying alcohol and drug usage. It captures a long-term record of alcohol and drugs through the preservation of biomarkers within the growing hair strand's fibers. Hair samples collected near the scalp can offer detection for roughly three months for substances. Hair sample collection is straightforward, tough to tamper with, and easily transportable.

A 1.5-inch portion consisting of around 200 hair strands (resembling a #2 pencil's thickness) nearest the scalp supplies 100mg of hair, the optimal amount for both screening and verification. For EtG, additional tests, or panels beyond 10, a specimen amounting to 150mg is advisable. It is best to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. 'Head hair' specifically refers to scalp hair, while 'body hair' includes all other varieties (like facial or axillary hair).

Process Overview

The primary phases in processing a sample for a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial lab processing. This step involves ensuring the sample was sealed and dispatched correctly, issuing an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any missing data entries absent from an electronic custody system.

Screening consists of an initial swift assessment for drug presence. Although Screening optimizes cost by ruling out drug usage in most samples, any positive screen needs verification for legal validity. Samples showing presumptive positive results in Screening necessitate a follow-up confirmation.

When Screening results suggest a presumptive positive, additional hair from the existing specimen is prepped for Extraction. At this step, hair drug levels are extracted at notably lower concentrations than comparable methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Positive Screening results receive validation through GC/MS, GC/MS/MS, or LC/MS/MS methods. Pre-confirmation, all presumptive positives undergo washing as needed. The lab process from Accessioning through Confirmation is examined according to the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Merits of hair drug testing:

• Extended detection period: Capable of identifying drug use up to 90 days, in contrast to the shorter timelines of urine tests.
• Difficult to alter: Hair drug tests resist manipulation to ensure more precise outcomes.
• Offers data over time: It reveals drug use patterns aggregating over a duration, not merely recent intake.

Drawbacks:

• Inability to detect recent consumption: Drugs typically become detectable in hair after 5-7 days.
• Higher expense: Hair drug testing tends to be pricier than alternative methods.
• Inconsistencies in findings: Variations in hair color and personal hair growth can impact drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests", the examination targets the hair strand itself rather than the follicle beneath the scalp.
