Hair Follicle Drug Testing - Murrieta, CA

What it is, How it works

Hair assessments have emerged as a substantial method for identifying drug and alcohol consumption. Hair acts as a long-term record of alcohol and drugs by capturing markers within the fibers of the growing hair strand. When collected near the scalp, hair can offer up to around a 3-month detection timeframe for alcohol and substances. It is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for both screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. We recommend employing a jeweler’s scale for weighting the specimen. In the absence of scalp hair, an equivalent amount of body hair may be used. In reference to head hair, this implies only scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The four critical stages in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab’s framework. This involves ascertaining that the sample was securely sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not supplied by an electronic chain of custody setup.

Screening is a preliminary rapid assessment for substances of abuse. Although Screening is an economical method to discount drug use in the bulk of samples, a positive screen requires validation to be legally acceptable. Any samples indicated as positive in Screening necessitate a follow-up confirmation.

If a positive result is implied during the Screening phase, more hair is extracted from the original specimen for Extraction. During this process, drugs are withdrawn from hair at much lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Validation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo a cleansing prior to confirmation, as required. The comprehensive lab procedure from Accessioning to Confirmation is subjected to review under both CAP (College of American Pathologists) Hair designation and the adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can trace drug use up to 90 days, in contrast to urine analyses which have a shorter detection period.
• Resilient to tampering: Cheating on a hair drug test is remarkably challenging, rendering the outcomes more reliable.
• Offers historical insight: It can reveal patterns of drug use over time, rather than just recent consumption.

Limitations:

• Incapable of detecting recent use: It requires roughly 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing is generally pricier than alternative drug screening methods.
• Result variability: Factors such as hair color and personal variations in hair growth can influence the level of drug metabolites in the hair.

Note: Although frequently termed "hair follicle tests", the analysis scrutinizes the hair strand rather than the hair 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.
