Hair Follicle Drug Testing - Pleasant Hill, IL

What it is, How it works

The utilization of hair testing has emerged as an effective means for detecting the use of drugs and alcohol. By capturing biomarkers in the strands of hair as they grow, hair serves as a long-term record of alcohol and drug consumption. When cut close to the scalp, hair can offer a detection window of up to approximately three months for both alcohol and drugs. This method is straightforward to administer, challenging to tamper with, and convenient to transport.

A hair sample of 1.5 inches, consisting of approximately 200 strands (comparable to the width of a #2 pencil), yields 100mg, which is the optimal amount for initial screening and thorough confirmation. For EtG, additional tests, or analyses exceeding 10 panels, a 150mg sample is advised. It is encouraged to weigh the specimen using a jeweler’s scale. In instances where scalp hair is not available, a similar quantity of body hair may be utilized. Note that when mentioning head hair, it specifically refers to scalp hair only, whereas body hair encompasses all other types (such as facial or axillary hair).

Process Overview

Laboratory processes for drug test results comprise four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase involving the integration of a sample into the laboratory system. This step includes confirming that the sample has been properly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional manual data entries not covered by an electronic chain of custody.

Screening entails an initial assessment for potential drug abuse. Although Screening is a cost-effective initial assessment tool, any positive findings require confirmation to be legally valid. Consequently, samples that return presumptively positive results necessitate subsequent confirmation procedures.

For any sample that shows a presumptive positive result during Screening, additional hair is extracted from the original sample for the Extraction phase. This stage involves extracting drugs at lower concentrations compared to other methods (such as urine or oral fluid tests), making hair drug screening one of the most challenging methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed for the Confirmation of any positive Screening results. All samples with presumptive positives undergo necessary washing before the confirmation process. The complete laboratory workflow, from Accessioning to Confirmation, meets the standards of both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for up to 90 days, as opposed to the shorter detection span of urine tests.
• Resistance to tampering: Cheating on a hair drug test is highly challenging, enhancing the accuracy of results.
• Historical insights: Hair testing allows for an assessment of drug use patterns over time rather than focusing only on recent usage.

Limitations:

• Inability to detect recent consumption: Drugs require approximately 5-7 days to become detectable in hair.
• Higher cost: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Factors like hair color and individual hair growth can influence drug metabolite concentrations in hair.

Note: Commonly referred to as "hair follicle tests," the analysis actually examines the hair strand and does not involve the hair follicle situated 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.
