Hair Follicle Drug Testing - Rougemont, NC

What it is, How it works

Utilizing hair samples has emerged as an influential method for identifying drug and alcohol usage. Hair acts as a long-term record for alcohol and drugs, capturing biomarkers within the strands of the hair shaft as it grows. With hair collected near the scalp, a detection period of roughly three months for alcohol and drugs can be achieved. Gathering hair is straightforward, hard to tamper with, and convenient for transport.

A sample measuring 1.5 inches consisting of around 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred sample amount for filtering and validating. For EtG, additional tests, and evaluations exceeding 10 panels, it is advised to use 150mg of hair. Using a jeweler's scale to measure the sample is suggested. Should scalp hair not be available, a similar portion of body hair can be obtained. In references to head hair, we mean scalp hair specifically. Body hair encompasses any other types, such as facial or axillary hair.

Process Overview

The primary stages in processing a drug test in a laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with initially integrating a sample into the laboratory’s processes. This step ensures the sample was properly sealed and delivered, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. While it is an economical option for excluding drug usage in the majority of samples, any positive screening result must be verified to be valid in legal contexts. Any samples preliminarily testing positive in Screening require subsequent confirmation.

Should a sample appear positive upon Screening, more hair is extracted from the original specimen for the Extraction process. This phase involves retrieving drugs from hair at concentrations lower than other methods (e.g., urine or oral fluid), which is why hair drug screening is notably challenging.

Verification of any positive screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminarily positive samples undergo a cleansing process prior to verification as necessary. The complete laboratory process from Accessioning to Confirmation is assessed under the guidelines of both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for as long as 90 days, surpassing the shorter detection timeframe of urine tests.
• Hard to falsify: Cheating a hair drug test is extremely challenging, thereby ensuring more precise outcomes.
• Yields historical insights: It offers a pattern of drug consumption over time, not merely capturing recent use.

Limitations:

• Inability to reveal recent consumption: Drugs become noticeable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing typically incurs higher costs compared to other methods of drug testing.
• Result variability: Factors such as hair shade and individual disparities in hair growth can impact the concentration of drug residues in the hair.

Note: Although frequently termed "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
