Hair Follicle Drug Testing - Wisner, NE

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol use. Hair serves as a chronic record of alcohol and drug presence by encapsulating biomarkers within the strands of hair during its growth. When hair is clipped close to the scalp, it can reveal drug and alcohol consumption over a period of up to roughly three months. Hair is easy to gather, relatively hard to tamper with, and straightforward to transport.

A hair sample measuring 1.5 inches, comprised of about 200 strands (approximating the thickness of a #2 pencil) and closest to the scalp, yields 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advisable. It is suggested to use a jeweler’s scale to weigh the hair. If scalp hair is unavailable, collecting an equivalent quantity of body hair is an option. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (such as facial and axillary hair).

Process Overview

The drug testing process in a laboratory primarily involves Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is incorporated into the lab's framework. This step involves checking that the sample was accurately sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent from an electronic chain of custody system.

Screening entails an initial swift assessment for substance abuse. Although Screening serves as an economical means to rule out drug presence in most samples, a confirmed positive result is necessary for legal admissibility. Samples that show preliminary positive results in Screening need further confirmation.

When a sample tests preliminarily positive during the Screening phase, additional hair is extracted from the original sample for the Extraction process. At this stage, drugs are isolated from the hair at lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is notably more challenging.

Confirmation of any positive Screening findings is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Prepared samples that are preliminarily positive undergo washing as necessary before confirmation. The comprehensive lab procedure, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can uncover drug consumption for up to 90 days, surpassing the shorter detection duration of urine tests.
• Challenging to manipulate: Hair drug tests are exceptionally difficult to deceive, ensuring more credible results.
• Historical insight: These tests offer a detailed timeline of drug use, not merely recent consumption.

Limitations:

• Inability to detect recent use: It generally takes 5-7 days for drugs to become traceable in hair.
• Higher cost: Hair drug tests typically incur higher costs than alternate drug testing methods.
• Result variability: Elements such as hair color and personal hair growth differences can influence drug metabolite concentration in the hair.

Note: Despite the common term "hair follicle tests", this test evaluates the hair strand itself, not 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.
