Hair Follicle Drug Testing - Almonte, CA

What it is, How it works

Hair analysis has evolved into a robust method for identifying substance and alcohol consumption. The hair captures a lasting record of alcohol and drug use by embedding biomarkers within the fibers of the elongating strand. When sampled near the scalp, hair offers as much as a 3-month detection period for substances. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.

A hair segment measuring 1.5 inches consisting of around 200 strands (comparable to a #2 pencil’s thickness) near the scalp yields 100mg, the optimal sample size for examinations and confirmations. For EtG, additional tests, or screenings beyond 10 panels, a specimen weighing 150mg is suggested. Using a jeweler’s scale is advised for precision in measuring the sample. If scalp hair isn't present, a comparable amount of body hair can be gathered. The term 'head hair' specifically refers to scalp hair, while 'body hair' encompasses all other hair types (facial, axillary, etc.).

Procedure Outline

The laboratory processing of a drug test involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial incorporation of a sample into a lab’s framework. This process ensures the sample was appropriately sealed and transported, a random LAN (Laboratory Accessioning Number) is assigned, and any supplemental data not supplied by an electronic chain of custody system is entered.

Screening serves as a preliminary assessment for detecting drugs of abuse. Although it's a cost-efficient technique to exclude drug usage for most samples, a positive screen requires confirmation for legal admissibility. Samples testing preliminarily positive during Screening necessitate a subsequent confirmation.

Should a sample test preliminarily positive during Screening, additional hair is extracted from the initial specimen for Extraction. Here, substances are drawn from the hair at concentrations significantly lower than in other testing methods (e.g., urine or saliva), making hair drug screening more demanding.

Confirmation of any positive screening finding is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing preliminary positives undergo a cleansing process before confirmation as necessary. The comprehensive laboratory sequence from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug intake up to 90 days, unlike urine tests that offer a shorter detection timeframe.
• Cheating resistance: Cheating a hair drug test proves extremely challenging, enhancing result accuracy.
• Historical data provision: It details a pattern of drug use over time, rather than just recent use.

Drawbacks:

• Incapable of detecting recent use: It takes approximately 5-7 days before drugs appear in hair.
• Expensive: Hair drug tests are generally costlier than alternative drug testing methods.
• Result variability: Elements such as hair color and personal variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: While often called "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.
