Hair Follicle Drug Testing - Emden, WA

What it is, How it works

Hair assessments are increasingly regarded as an effective means for identifying drug and alcohol consumption. The hair strand's growth embeds biomarkers, offering a prolonged history of substance use. When collected near the scalp, hair can provide a detection period of up to three months for alcohol and other substances. Hair is easy to gather, somewhat challenging to tamper with, and straightforward to transport.

A 1.5-inch segment consisting of roughly 200 hairs (approximately the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for testing and confirmation. For EtG, supplemental tests, and/or those exceeding 10 panels, 150mg of hair is advised. It is suggested to weigh the specimen using a jeweler’s scale. In situations where scalp hair isn't accessible, a comparable quantity of body hair may be used. Head hair specifically refers to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory process for drug testing encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a lab system, ensuring the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry that an electronic chain of custody system might not cover.

Screening is an initial, rapid evaluation for drugs of abuse. Although Screening is a cost-effective method to exclude drug use for most samples, a positive screening result needs to be confirmed to be accepted legally. Any samples that test positive initially in Screening require additional confirmation.

For samples that test positive initially in the Screening, further hair is collected from the original sample for Extraction. During this phase, drugs are concentrated from hair at a much lower level than in other methods (e.g., urine or oral fluid), which makes hair drug testing more challenging.

Any confirmed positive screening is validated via GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are cleansed before confirmation, as needed. The complete laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can identify drug use for as long as 90 days, whereas urine analyses offer a shorter detection period.
• Hard to falsify: Falsifying hair drug tests is very difficult, resulting in more reliable outcomes.
• Shows usage patterns: It can reveal a pattern of drug use over time, not just recent usage.

Limitations:

• Inability to detect recent usage: It takes approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug analyses are usually more costly compared to other testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: Often called "hair follicle tests", the testing focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
