Hair Follicle Drug Testing - Exeter, PA

What it is, How it works

Hair analysis has emerged as an effective means for identifying the consumption of substances such as drugs and alcohol. By embedding biomarkers within the hair's fibers as it grows, hair provides a prolonged history of substance use. When collected near the scalp, hair can reveal substance use dating back up to around three months. Collection is straightforward, manipulation is challenging, and transportation is convenient.

Collecting a hair sample of 1.5 inches made up of approximately 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for testing and validation. For EtG, additional testing, or panels exceeding 10, it's recommended to have 150mg of the sample. Employ a jeweler’s scale to measure the sample weight. If scalp hair isn’t available, an equivalent amount of body hair can be used. Specifically, scalp hair refers to head hair only. Body hair encompasses all other types such as facial and axillary hair.

Process Overview

The key stages in laboratory drug test analysis include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the sample's initial integration into the lab’s system. This step ensures the sample's proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and fills in any information not captured by an electronic chain of custody system.

Screening serves as a preliminary assessment for substance abuse. Although cost-effective for eliminating drug presence in most samples, a positive screening result necessitates confirmation to be legally valid. Samples highlighted as positive through Screening must undergo further confirmation.

For samples marked as positive during Screening, additional hair is selected from the initial sample for the Extraction phase. Here, drugs are extracted from hair at notably lower concentrations compared to other techniques (e.g., urine or oral fluids), which is why hair analysis is among the most challenging methodologies.

Confirmation of a positive result utilizes techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are meticulously cleaned before confirmation if necessary. The entire lab procedure from Accessioning through to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and aligns with the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Detects drug use up to 90 days, as opposed to the shorter detection scope of urine tests.
• Hard to deceive: The difficulty in circumventing hair tests contributes to their reliability.
• Historical consumption insight: Provides a record of drug use over time rather than only recent use.

Limitations:

• Non-detection of recent use: Drugs are detectable in hair after about 5-7 days.
• Expense: Hair testing tends to be pricier than alternative methods.
• Result variability: Factors like hair color and personal differences in hair growth can influence the drug metabolite concentration in hair.

Note: Despite the common term "hair follicle tests", the analysis focuses on the hair strand and not the follicle beneath the scalp.
