Hair Follicle Drug Testing - St. Ignatius, MT

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers in the strands as they grow. When taken close to the scalp, a hair sample can reveal alcohol and drug use for up to around three months. Collecting hair is straightforward, relatively tamper-resistant, and easily transportable.

A sample size of about 200 hair strands (approximately the width of a #2 pencil) measuring 1.5 inches from the scalp will yield 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, a sample of 150mg is advised. Using a jeweler’s scale to measure the specimen is suggested. In the absence of scalp hair, an equivalent amount of body hair may be extracted. References to head hair pertain only to scalp hair, while body hair signifies all other hair types (facial, axillary, etc.).

Process Overview

The four fundamental phases in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial introduction of a sample into a lab’s protocol, verifying proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data entries that an electronic chain of custody system may lack.

Screening consists of a preliminary assessment for substance abuse. Although Screening is an economical method to eliminate drug use suspect in most samples, a positive result necessitates confirmation for legal admissibility. Samples yielding presumptively positive results in Screening must undergo subsequent verification.

Should a sample indicate a presumptive positive in the Screening phase, additional hair from the primary specimen is prepared for Extraction. In this process, drugs are isolated from hair at concentrations lower than those found in alternative techniques (e.g., urine or oral fluid), adding complexity to hair drug screening.

The Confirmation of positive screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation when necessary. The complete lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation, in conjunction with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug assays can identify substance use up to 90 days back, whereas urine assays have a narrower detection timeframe.
• Difficult to falsify: Cheating on a hair drug test is notably challenging, enhancing result accuracy.
• Chronological data provision: It reveals patterns of substance use over time, unlike just recent usage.

Limitations:

• Incapable of identifying immediate use: Drugs only become traceable in hair after 5-7 days approximately.
• Expense: Hair drug assays usually incur a higher cost relative to other drug testing approaches.
• Result variability: Individual factors like hair color and growth rates can influence drug metabolite levels in hair.

Note: Despite being termed "hair follicle tests", this assay analyzes the hair strand itself, not the underneath scalp follicle.

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.
