Hair Follicle Drug Testing - Rock Point, MD

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair encapsulates a comprehensive timeline of alcohol and drug use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer a detection timeframe of up to approximately three months for alcohol and substances. It is straightforward to gather, relatively tamper-resistant, and convenient to transport.

Gathering a 1.5-inch segment consisting of around 200 hair strands (approximately the diameter of a #2 pencil) proximal to the scalp yields a 100mg ideal sample for testing and verification. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is preferred. Utilizing a jeweler’s scale for weighing the specimen is advisable. In cases where scalp hair is inaccessible, an equivalent quantity of body hair can be used. 'Head hair' pertains specifically to scalp hair. 'Body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory phases for generating a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial intake of a sample into a lab's system, verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional necessary data entry absent from an electronic chain of custody system.

Screening serves as an initial rapid evaluation for substance abuse. While cost-efficient for eliminating drug consumption in most samples, a positive result in screening mandates confirmation for court admissibility. Presumptively positive samples in Screening necessitate secondary confirmation.

When a sample yields a presumptive positive at the Screening stage, additional hair from the original sample is required and prepared for Extraction. This phase involves removing drugs from hair at a significantly lower concentration compared to methods like urine or oral fluid, which underscores hair drug testing as a challenging procedure.

GC/MS, GC/MS/MS, or LC/MS/MS are used to confirm any positive findings from screening. Prior to confirmation, all presumptively positive samples undergo washing as needed. The comprehensive lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug intake for up to 90 days, unlike urine tests with shorter periods.
• Difficult to manipulate: Cheating a hair drug test is challenging, ensuring more reliable results.
• Establishes historical data: Allows tracking of drug use patterns over time, beyond immediate consumption.

Limitations:

• No immediate detection: Requires about 5-7 days for drugs to become noticeable in hair.
• Expense: Hair tests generally cost more than other testing techniques.
• Result variances: Elements like hair color and personal growth differences influence drug metabolite concentration in the hair.

Note: Commonly termed "hair follicle tests", this assessment examines the hair strand and not the follicle beneath the scalp
