Hair Follicle Drug Testing - Evart, MI

What it is, How it works

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. It provides an extended history of substance use by capturing biomarkers within the fibers of the hair as it grows. When hair samples are taken close to the scalp, they can offer a detection timeline of up to 3 months for both alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch hair specimen, approximately 200 strands thick (similar to the diameter of a #2 pencil), located nearest the scalp, yields around 100mg of hair—optimal for screening and confirmation. For EtG tests, additional tests, or panels exceeding 10, a 150mg sample is advised. It is suggested to weigh the specimen using a jeweler’s scale. Should scalp hair be unobtainable, a comparable quantity of body hair can be used instead. References to head hair imply scalp hair specifically, whereas body hair indicates all other types of hair (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result incorporates four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the entry of a sample into the laboratory’s system. This step includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary inspection for drugs of abuse. Although Screening is an economical approach to dismiss drug use in most samples, a positive result requires confirmation to be valid in legal situations. Samples that are presumptively positive during Screening necessitate a follow-up confirmation.

In instances where Screening suggests a positive result, additional hair is taken from the original sample and prepared for Extraction. During Extraction, drugs are removed from hair at lower concentrations compared to other methods (such as urine or oral fluid) making hair drug testing a more complex methodology.

GS/MS, GC/MS/MS, or LC/MS/MS techniques are employed for Confirmation of any positive findings from Screening. Presumptive positive samples undergo washing before confirmation as required. The comprehensive laboratory process, spanning from Accessioning to Confirmation, is conducted under both CAP (College of American Pathologists) Hair designation and in compliance with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a briefer detection period.
• Resistance to falsifications: Cheating a hair drug test is extremely challenging, thereby enhancing accuracy.
• Provides usage history: It offers insights into drug use patterns over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: It typically takes around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing methods.
• Result variability: Variables like hair color and individual hair growth can affect drug metabolite concentrations in hair strands.

Note: Despite commonly being called "hair follicle tests", the testing process analyzes 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.
