Hair Follicle Drug Testing - Galesburg, MI

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. The hair captures a long-term record of alcohol and other drug consumption by embedding biomarkers within the fibers of the hair strand as it grows. Hair collected near the scalp can reveal up to an estimated 3-month window of detection for alcohol and other drugs. Collecting hair is straightforward, hard to tamper with, and convenient for shipping.

A sample of approximately 1.5 inches of about 200 hair strands (akin to the thickness of a #2 pencil) from the scalp region yields 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or evaluations exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the specimen using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected. References to head hair mean scalp hair exclusively. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into the lab's system. This process includes ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry not facilitated by an electronic chain of custody.

Screening provides an initial assessment for the presence of drugs of abuse. Although Screening is an economical approach to rule out drug use in most samples, a positive screen must be validated to be legally defensible. Samples that show a presumptive positive in Screening require follow-up confirmation.

If the Screening stage indicates a presumptive positive, additional hair is extracted from the initial sample and prepped for Extraction. At this point, drugs are isolated from hair at concentrations significantly lower than in other testing techniques (such as urine or saliva), underlining the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive screening outcomes. All samples that are presumptive positive undergo washing before confirmation if necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and the accreditation to ISO / IEC 17025 specifications.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can indicate drug use for up to 90 days, unlike urine tests, which have a shorter detection span.
• Challenging to manipulate: Cheating a hair drug test is highly challenging, ensuring more reliable results.
• Offers historical insight: It reveals a timeline of drug use over time, rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs take around 5-7 days to be traceable in hair.
• Expense: Hair drug tests are typically more costly compared to other drug testing methods.
• Result variability: Drug metabolite concentrations in hair can be affected by factors like hair color and personal hair growth differences.

Note: Although often labeled as "hair follicle tests", the analysis concerns the hair strand, not 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
