Hair Follicle Drug Testing - Ahwahnee, CA

What it is, How it works

Hair testing is recognized as an effective method for identifying substance and alcohol usage. This method offers an extended history by sequestering biomarkers in the fiber structure of growing hair strands. When sourced near the scalp, hair can reveal drug and alcohol presence within an approximate three-month timeframe. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands, comparable in size to a #2 pencil, adjacent to the scalp yields 100mg of hair, the optimal quantity for testing and validation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We propose using a jeweler’s scale for measuring the specimen. If scalp hair cannot be accessed, a similar volume of body hair can be utilized. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The four pivotal steps in the lab analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a laboratory sample. This step confirms that the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fulfills any additional data recording not covered by an electronic chain of custody.

Screening provides an initial rapid assessment for drugs. Although Screening is cost-efficient to eliminate drug usage in most samples, a positive screening outcome necessitates verification for legal acceptance. Samples with presumed positives during Screening must proceed to secondary confirmation.

Samples indicating a positive result in the Screening step undergo additional hair extraction from the original sample for the Extraction phase. At this stage, drugs are separated from hair at reduced concentrations compared to other techniques (e.g., urine or oral fluids), demonstrating why hair drug analysis is notably complex to conduct.

Confirmation for any positive screening outcome uses GC/MS, GC/MS/MS or LC/MS/MS techniques. All presumptive positive samples undergo pre-confirmation cleansing if required. The full laboratory workflow from Accessioning to Confirmation is scrutinized per both the CAP (College of American Pathologists) Hair guidelines and accreditation per ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses detect substance use up to 90 days, unlike urine tests with shorter detection durations.
• Hard to manipulate: Cheating a hair drug analysis is very difficult, enhancing accuracy.
• Supplies historical insight: Offers a consumption outline over time, beyond just recent use.

Limitations:

• Incapable of indicating recent use: Drugs require roughly 5-7 days to be present in hair.
• Expense: Hair drug analyses typically incur higher costs than other methods.
• Result variability: Variables like hair color and personal hair growth rates can influence metabolite concentration within hair.

Note: Commonly labeled as "hair follicle tests", these tests analyze the strand, not 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. 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.
