Hair Follicle Drug Testing - Mccormick, IL

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. It offers a detailed history of alcohol and drugs by capturing biomarkers in the hair's fibrous structure as it grows. Collected near the scalp, it can present a detection period of roughly three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easily transported.

A sample measuring 1.5 inches, consisting of about 200 hairs (akin to the thickness of a #2 pencil) near the scalp, yields 100mg, which is an optimal sample for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is recommended. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair comprises any other hair forms (facial, axillary, etc.).

Process Overview

The laboratory drug testing process encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the process by integrating a sample into the laboratory's system. This step verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entries absent from an electronic chain of custody system.

Screening serves as an initial rapid assessment for drug abuse. Although it's an economical method to eliminate drug usage in most samples, a positive screen result must be confirmed for court acceptance. Samples with presumptive positive results in Screening require further confirmation.

If Screening suggests a positive result, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug screening is one of the most complex methods to execute.

Confirmation of positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected to be positive are washed prior to confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and follows the ISO / IEC 17025 standards for accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug use up to 90 days, as opposed to urine tests with a shorter window.
• Difficulty to cheat: Cheating a hair drug test is quite challenging, leading to more precise results.
• Provides historical data: It offers a timeline of drug use over an extended duration, not merely recent usage.

Limitations:

• Cannot detect recent use: Drugs require roughly 5-7 days to be traceable in hair.
• Cost: Generally, hair drug tests are more costly in comparison to other testing methods.
• Variations in results: Elements like hair color and individual hair growth differences can impact the drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the analysis focuses on 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.
