Hair Follicle Drug Testing - Lester, WV

What it is, How it works

Hair analysis has emerged as a significant method for uncovering drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the growing hair strand's fibers. When collected near the scalp, hair can provide a detection timeframe of up to 3 months for alcohol and substances. Collecting hair is straightforward, difficult to tamper with, and convenient to transport.

A 1.5-inch sample, containing around 200 strands of hair (roughly the thickness of a #2 pencil) from just below the scalp will yield 100mg, the optimal amount for screening and verification. For EtG, additional tests, and/or assessments exceeding 10 panels, a 150mg sample is advisable. It is suggested to use a jeweler’s scale for precision. If scalp hair is absent, an equivalent quantity of body hair may be used. References to head hair pertain only to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary integration of a sample into a laboratory’s system. This involves confirming that the sample was appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.

Screening consists of an initial cursory check for drug abuse. Although Screening is a cost-effective way to dismiss drug usage in most samples, a positive screen must be confirmed for court admissibility. Any samples that show presumptive positives during Screening necessitate secondary confirmation.

For samples showing presumptive positivity in Screening, additional hair is extracted from the original specimen and prepped for Extraction. In Extraction, drugs are drawn out from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging technique to execute.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples yielding presumptive positives are cleaned prior to confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection span: Hair drug tests detect drug usage over a period reaching up to 90 days, as opposed to urine tests with a shorter detection span.
• Challenging to falsify: Hair drug tests are hard to manipulate, ensuring result accuracy.
• Historical usage pattern: It reveals a pattern of drug usage over time, not just recent consumption.

Limitations:

• Incapable of detecting recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternative drug testing methods.
• Result variability: Variables like hair color and personal hair growth differences can impact drug metabolite concentrations in hair.

Note: Though often called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lester, WV, hair follicle testing clearly outshines urine testing. These tests offer longer detection windows and are celebrated for their accuracy and reliability.
