Hair Follicle Drug Testing - Stirling City, CA

What it is, How it works

Hair analysis has emerged as an effective approach for identifying drug and alcohol consumption. It offers an extended history of alcohol and various drugs by embedding biomarkers within the strands of growing hair. When sourced near the scalp, hair gives up to an estimated 3-month history for alcohol and other drugs. Collecting hair is straightforward, somewhat tough to tamper with, and easy to transport.

A segment measuring 1.5 inches containing around 200 hair strands (roughly the dimension of a #2 pencil) from nearest the scalp yields 100mg of hair, perfect for examination and verification. For EtG, additional tests, or panels above 10, 150mg of the sample is advisable. Using a jeweler’s scale to weigh the specimen is suggested. If scalp hair isn’t available, a similar portion of body hair may be gathered. Head hair specifically implies scalp hair. Body hair covers all other types (beard, axillary, etc.).

Process Overview

The four essential procedures in a lab’s drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample into a lab’s records. This incorporates confirming the sample was sealed and dispatched accurately, allotting a distinct LAN (Laboratory Accessioning Number), and finishing any missing data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for substance abuse. While it’s a budget-friendly way to eliminate drug presence for most samples, a positive screen must be confirmed for court acceptance. Any samples with a presumptive positive in Screening require another confirmation step.

In cases of presumptive positives at the Screening phase, more hair is taken from the initial sample and readied for Extraction. During this phase, substances are withdrawn from hair at much lower concentrations than other methods (e.g., urine or saliva), which is why hair drug screening remains the toughest method to execute.

Confirmation of any positive screen is managed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a cleansing before confirmation if necessary. The complete laboratory operation from Accessioning to Confirmation falls under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug exams can identify drug usage for as long as 90 days, compared to urine tests with shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is exceedingly challenging, ensuring more precise outcomes.
• Offers historical insight: It delivers a drug use timeline over various periods, beyond immediate use.

Limitations:

• Inability to find recent use: Drugs become detectable in hair approximately 5-7 days post-usage.
• Expense: Hair drug tests typically incur higher costs than other methods.
• Result variability: Elements like hair color and individual hair growth variability can influence drug metabolite levels in the hair.

Note: While commonly called "hair follicle tests", the analysis actually examines the hair strand, not the follicle under 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.
