Hair Follicle Drug Testing - Mills River, NC

What it is, How it works

Hair analysis has become recognized as a formidable resource for identifying drug and alcohol consumption. Hair retains a prolonged history by enclosing biomarkers within the structure of its growing strand. Shorn near the scalp, hair can supply an estimated 3-month window for detecting both alcohol and other substances. It is straightforward to collect, somewhat challenging to tamper with, and convenient to transport.

A specimen measuring 1.5 inches of about 200 hair strands (approximately as thick as a #2 pencil) near the scalp yields 100mg, the preferred quantity for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. Employ a jeweler’s scale for accurate measurement of the specimen. If head hair is unavailable, a similar quantity of body hair is permissible. When citing head hair, we exclusively mean scalp hair. Body hair includes any other hair variety (facial, underarm, etc.).

Process Overview

The laboratory procedure for processing a drug test result is composed of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial intake of a sample within a laboratory's framework. The procedure involves ensuring the sample was appropriately sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any remaining data entry not covered by an electronic chain of custody mechanism.

Screening provides a preliminary assessment for illicit drugs. Though Screening is cost-efficient for dismissing drug usage in most specimens, a positive outcome necessitates validation for legal admissibility. Samples preliminarily positive in Screening demand subsequent confirmation.

In instances of presumptive positives from the Screening stage, additional hair is retrieved from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other techniques (such as urine or saliva), contributing to hair drug screening's complexity.

The verification of any positive Screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples initially marked positive are cleansed before verification as per requirements. The entire laboratory workflow from Accessioning to Confirmation is examined under the oversight of the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing reveals drug consumption for as long as 90 days, unlike urine testing which offers a more limited detection period.
• Hard to manipulate: It is extremely hard to falsify a hair drug test, leading to more reliable outcomes.
• Incorporates historical data: Capable of illustrating a usage pattern over time rather than just recent consumption.

Limitations:

• Unable to detect recent use: A time frame of 5-7 days is needed for drugs to become apparent in hair samples.
• Expense: Hair drug assessments tend to cost more than other testing approaches.
• Result variability: Attributes like hair pigment and personal variations in hair growth can influence drug metabolite concentration in hair samples.

Note: Although commonly termed as "hair follicle tests", the examination focuses on the hair strand instead of the follicle beneath the scalp.
