Hair Follicle Drug Testing - West Lincoln, NE

What it is, How it works

Hair analysis is now considered an influential approach for identifying drug and alcohol consumption. Hair captures a prolonged history of these substances by embedding biomarkers within its growing strands. When gathered near the scalp, hair can reveal a detection period of roughly three months for drugs and alcohol. The sampling process is straightforward, relatively resistant to tampering, and convenient to transport.

Obtaining a 1.5-inch segment comprising about 200 hairs (similar to the width of a #2 pencil) from the scalp yields 100mg, an optimal quantity for both screening and verification. For EtG and examinations exceeding 10 panels, 150mg is advised. A jeweler’s scale is suggested for weighing the sample. In the absence of scalp hair, a comparable mass of body hair may be utilized. References to head hair specifically pertain to scalp hair alone. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four primary stages in the laboratory processing of a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial admittance into a lab’s system. This phase ensures proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and inputs any further data absent in an electronic chain of custody system.

Screening involves a preliminary swift assessment for substances of abuse. Although Screening is an economical means to exclude drug use in most samples, positive findings require confirmation to stand in legal contexts. Any samples that yield a presumptive positive in Screening necessitate a subsequent confirmation.

Should a sample be taken as positive in the Screening stage, additional hair is taken from the initial sample for Extraction. During this phase, drugs are extracted at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening methodologies.

Confirmation of any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed pre-confirmation as required. The comprehensive laboratory operation from Accessioning to Confirmation abides by both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can detect substance use up to 90 days, surpassing urine tests which offer a briefer detection period.
• Challenging to deceive: Cheating a hair drug test is notably difficult, thus enhancing result accuracy.
• Historical data provision: It offers a consumption pattern over time, not just immediate use.

Limitations:

• Incapable of detecting recent use: A period of about 5-7 days is required before drugs become detectable in hair.
• Expense: Generally, hair drug tests incur higher costs compared to alternate testing methods.
• Result variability: Influences such as hair color and individual hair growth rates can affect drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the analysis focuses on 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.
