Hair Follicle Drug Testing - Tazewell, VA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The fibers of the growing hair capture biomarkers, delivering an extensive timeline of alcohol and drug intake. When sampled near the scalp, hair offers up to a three-month detection period for substances. It is straightforward to gather, challenging to tamper with, and easy to send.

A 1.5-inch segment of approximately 200 hair strands (comparable to the circumference of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimum quantity for testing and verification. In cases involving EtG, additional screenings, or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for precise measurement. If scalp hair is unavailable, a similar quantity of body hair may be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (such as facial and underarm hair).

Process Overview

Drug test processing in the laboratory comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially integrated into a lab’s system. It involves confirming the proper sealing and shipment of the sample, assigning a random Laboratory Accessioning Number (LAN), and finalizing any extra data entry absent from an electronic chain of custody.

Screening includes an initial rapid assessment for detection of substance abuse. While it is a cost-effective approach to exclude drug use in most samples, a positive result from screening must be verified for legal validity. Any samples that are suspected to be positive during Screening require further confirmation.

For samples suspected as positive during Screening, additional hair is prepared from the original sample for Extraction. This phase involves isolating drugs from hair at concentrations much lower than those in other assessments (e.g., urine or saliva), making hair testing a challenging method.

GC/MS, GC/MS/MS, or LC/MS/MS is utilized to confirm any positive screening outcome. All presumptive positive samples undergo washing before confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair guidelines and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, whereas urine tests have a narrower detection timeline.
• Challenging to falsify: The difficulty in manipulating a hair drug test renders the results more reliable.
• Offers historical insight: It provides an overview of drug use over time, not just recent activities.

Limitations:

• Incapable of detecting recent consumption: It requires roughly 5-7 days for substances to show in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing forms.
• Result variability: Characteristics such as hair color and individual differences in hair growth can influence the concentration of drug residues in hair.

Note: While commonly termed as “hair follicle tests,” the test examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Tazewell, VA, hair follicle testing outshines traditional urine tests. Hair tests boast superior accuracy and reliability, with their ability to detect substances over extended periods.
