Hair Follicle Drug Testing - Alvan, IL

What it is, How it works

Hair analysis is now renowned as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive timeline of alcohol and substance use by capturing biomarkers within the fiber of the developing hair strand. When extracted near the scalp, hair can provide up to roughly a 3-month detection period for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to transport.

A 1.5-inch portion containing around 200 strands (roughly the thickness of a #2 pencil) closest to the scalp produces 100mg of hair, deemed the optimal sample size for screening and verification. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample with a jeweler’s scale. If scalp hair isn’t accessible, an equivalent amount of body hair can be obtained. When mentioning head hair, we solely refer to scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory workflow for processing a drug test result encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial input of a sample into a lab’s system. It includes checking that the sample was sealed and sent appropriately, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by an electronic chain of custody system.

Screening provides an initial assessment for drugs of abuse. Although Screening is an economical approach to exclude drug use in most samples, a positive screen must be confirmed to hold up in court. Any samples that are presumably positive in Screening necessitate additional confirmation.

If a sample appears presumptively positive during the Screening stage, more hair is taken from the initial sample and prepped for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other testing methods (like urine or oral fluids), making hair drug screening the most challenging method to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo washing before confirmation if needed. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug consumption for up to 90 days, whereas urine tests provide a shorter detection span.
• Difficulty in falsification: Manipulating a hair drug test is extremely difficult, enhancing result accuracy.
• Supplies historical information: It can display a trend of drug use over time, beyond just recent consumption.

Limitations:

• Cannot identify recent consumption: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug assessments are generally costlier than alternative drug testing methods.
• Variability in outcomes: Aspects like hair color and personal differences in hair growth can influence drug metabolite content in hair.

Note: Though often termed "hair follicle tests", the examination evaluates the hair strand, 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.
