Hair Follicle Drug Testing - Elmwood, LA

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by embedding biomarkers within the strands as they grow. Collected near the scalp, hair can reveal drug or alcohol use for a period of up to around three months. The collection process is straightforward, the potential for tampering is minimal, and it is easy to transport.

A 1.5-inch portion comprising around 200 hair strands (roughly the diameter of a #2 pencil) taken near the scalp provides 100mg of hair, which is the optimal sample amount for analysis and verification. For EtG, additional tests, and/or examinations exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample with a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be obtained. When indicating head hair, we refer specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introduction of a specimen into the lab’s system, ensuring the sample was correctly sealed and sent, generating a unique LAN (Laboratory Accessioning Number), and completing any requisite data entry absent from an electronic chain of custody system.

Screening involves an initial rapid assessment for drug use. While Screening serves as an economical means to dismiss substance use in the majority of cases, a positive result requires verification to stand legal scrutiny. Any samples showing presumptive positives in Screening demand further confirmation.

When a sample indicates a presumptive positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are extracted from hair in lower concentrations compared to other methods (e.g., urine or oral fluids), which highlights why hair drug analysis is among the most complex methods to execute.

Positive screening findings undergo Confirmation through GC/MS, GC/MS/MS or LC/MS/MS. All samples indicating presumptive positives undergo cleansing before confirmation if necessary. The complete laboratory sequence from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation in alignment with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can identify drug consumption for up to 90 days, unlike urine tests with shorter detection windows.
• Challenging to falsify: It is notably difficult to manipulate hair drug testing, thus enhancing result accuracy.
• Historical insights: It delivers a usage trend over time rather than just recent consumption.

Limitations:

• Unable to detect recent use: Drugs require approximately 5-7 days to become traceable in hair.
• Expense: Hair drug analysis typically incurs higher costs than alternate drug testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth can impact drug metabolite levels in the hair.

Note: Though commonly termed "hair follicle tests", the examination pertains to the hair strand rather than the hair follicle below 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.
