Hair Follicle Drug Testing - Clio, CA

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. The fibers of a growing hair strand can encapsulate biomarkers, providing a chronicled history of alcohol and drug use. When gathered from near the scalp, hair can deliver a detection window extending up to three months for both alcohol and drugs. Collecting hair samples is straightforward, challenging to tamper with, and convenient for transportation.

A specimen of 1.5 inches consisting of approximately 200 hairs (approximating the size of a #2 pencil) located nearest the scalp yields 100mg of hair, which is considered the optimal sample for both initial testing and confirmation. For EtG, supplementary tests, or panels exceeding 10, a 150mg specimen is advisable. It's beneficial to measure the specimen using a jeweler’s scale. Should scalp hair be inapplicable, an equivalent quantity of body hair can be used. Head hair specifically refers to scalp hair, while body hair pertains to all other types (such as facial and axillary hair).

Process Overview

The processing of a drug test in a laboratory encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary handling of a sample within the laboratory's infrastructure. This step involves checking the integrity of the sample's seal and packaging, assigning a random Laboratory Accessioning Number (LAN), and completing any data entry missed by the electronic chain of custody system.

Screening is a rapid preliminary test for identifying drugs of abuse. While cost-efficient for excluding drug use in most samples, any positive screening result requires confirmation for legal acceptability. Presumptive positives at this stage necessitate additional verification.

If a presumptive positive arises during Screening, excess hair from the original sample is extracted for further analysis. Here, drugs are extracted at concentrations much lower than found in alternative test methods (i.e. urine or oral fluids), explaining the challenge associated with hair drug screening.

To confirm positive screening outcomes, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Any presumptive positives undergo necessary washing before final confirmation. This process spans from Accessioning to Confirmation, all reviewed under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests track drug consumption up to 90 days, surpassing the shorter window of urine tests.
• Resistance to falsification: Cheating a hair drug test is notably challenging, enhancing result reliability.
• Historical data insight: It charts a pattern of drug use over time, beyond recent activities.

Limitations:

• Lacks recent use detection: Hair requires approximately 5-7 days before drugs become detectable.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Results variability: Hair color and individual hair growth variations can influence drug metabolite concentrations.

Note: Despite the term "hair follicle tests," the analysis focuses on the hair strand, not the scalp-embedded follicle.

Why Hair Follicle Testing Beats Urine Testing

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.
