Hair Follicle Drug Testing - Lloydell, PA

What it is, How it works

Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol consumption. Hair retains prolonged records of alcohol and drug presence through biomarkers ensnared within the strands' fibers. When collected near the scalp, hair offers a detection timeframe extending up to 90 days for alcohol and various drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.

A hair sample of 1.5 inches, comprising approximately 200 strands (about the thickness of a #2 pencil), nearest to the scalp yields 100mg, the preferred amount for screening and confirmation. For EtG, additional tests, or tests exceeding ten panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for sample weighing is recommended. In cases where scalp hair is unattainable, a similar volume of body hair might be used. References to head hair denote only scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory process for a drug test comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into the lab's system. This phase ensures the sample's proper sealing and shipping, the assignment of a random LAN (Laboratory Accessioning Number), and finalizing any additional data recording absent from an electronic chain of custody system.

Screening constitutes an initial, swift evaluation for drugs of abuse. While cost-effective for dismissing drug use in most samples, positive screens demand confirmation for courtroom admissibility. Samples flagged as presumptively positive in Screening necessitate secondary confirmation.

For samples preliminarily positive in Screening, further hair is sourced from the initial collection and prepped for Extraction. Here, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug analysis comparatively challenging.

Confirmation is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methods for any positive screening results. Presumptive positive samples undergo necessary washes before confirmation. The comprehensive laboratory process, from Accessioning to Confirmation, is assessed under CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use over a period of up to 90 days, unlike urine tests, which offer a shorter detection period.
• Resistance to tampering: Cheating a hair drug test is exceedingly difficult, ensuring more precise outcomes.
• Historical usage insight: It reveals a pattern of drug use over time, beyond immediate consumption.

Limitations:

• Incapacity for recent use detection: Drugs typically become detectable in hair only after about 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to alternate drug testing procedures.
• Result variability: Individual aspects such as hair color and growth differences can influence drug metabolite concentration in hair.

Note: Commonly dubbed "hair follicle tests," the procedure assesses 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.
