Hair Follicle Drug Testing - Lakeland North, WA

What it is, How it works

The assessment of hair has increasingly been recognized as an effective resource for identifying drug and alcohol consumption. Hair retains a long-lasting record of substances by embedding markers within the structure of the hair as it grows. When obtained near the scalp, hair can reveal a detection timeline for alcohol and other drugs stretching up to about three months. It's straightforward to gather, not easily tampered with, and convenient to transport.

A sample measuring 1.5 inches consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) gathered nearest to the scalp supplies 100mg of hair, the prime sample size for analysis and validation. For EtG, additional testing, and/or assessments exceeding 10 panels, a specimen of 150mg is favored. It's advisable to measure the sample with a jeweler’s scale. In the absence of head hair, an equivalent quantity of body hair may be utilized. By 'head hair,' we mean exclusively the hair on the scalp. 'Body hair' encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result is comprised primarily of four phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample into a lab’s database. This step entails confirming that the sample was correctly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by a digital chain of custody protocol.

Screening represents a preliminary, swift assessment for substance misuse. While Screening is an economical solution for eliminating drug use across most samples, a positive result must be validated to be permissible in judicial proceedings. Samples indicated as positive during Screening necessitate further confirmation.

When a sample tests positive in the Screening stage, additional hair is sourced from the original specimen and prepared for Extraction. Here, the substances are isolated from the hair at a significantly reduced concentration compared to other techniques (e.g., urine or saliva), rendering hair drug screening the most challenging technique to execute.

The verification of any positive screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples that are presumptively positive are cleansed as required before confirmation. The complete laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair recognition and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug assessments can identify drug use for up to 90 days, in contrast to urine tests that offer a briefer detection period.
• Cheating is difficult: Evading a hair drug test is very challenging, ensuring more precise outcomes.
• Historical insight: It can reveal a drug use trend over a timeframe, not merely recent consumption.

Limitations:

• Not effective for detecting recent use: It requires about 5-7 days for drugs to become observable in hair.
• Expense: Hair drug assessments generally incur higher costs than alternative testing methods.
• Result variability: Elements such as hair coloration and personal differences in hair growth can influence the levels of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the testing process examines the hair strand rather than the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
