Hair Follicle Drug Testing - Talmage, CA

What it is, How it works

The perception of hair testing as an effective method for identifying substance use has grown considerably. Hair captures biomarkers of drugs and alcohol within the strands as they grow, offering a prolonged record of consumption. When extracted near the scalp, hair can offer a detection reach of up to roughly three months for drugs and alcohol. The collection process is straightforward, the potential for tampering is relatively low, and shipping is uncomplicated.

A 1.5-inch sample consisting of around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for analysis and confirmation. For EtG, additional testing, and/or panels surpassing 10, 150mg of hair is advised. Utilizing a jeweler’s scale for measurement is suggested. In the absence of scalp hair, an equivalent amount of body hair can be collected. References to head hair specifically imply scalp hair, while body hair denotes any other types (e.g., facial, axillary).

Process Overview

The core stages in the lab analysis of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial entry into the laboratory’s system. This encompasses checking that the sample is securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not captured by an electronic chain of custody system.

Screening is a preliminary examination for substances of abuse. Though Screening offers a cost-effective means of ruling out substance usage in most samples, a positive screen necessitates confirmation for legal admissibility. Samples yielding a presumptive positive result from Screening require additional confirmation.

Upon a presumptive positive outcome in Screening, more hair is retrieved from the original sample and refined for Extraction. During this phase, drug residues are extracted from hair at considerably lower levels than other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.

To confirm any positive screening findings, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. All presumptive positive samples undergo washing pre-confirmation as needed. Each step from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and is accredited according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use up to 90 days back, whereas urine tests offer a shorter detection range.
• Hard to manipulate: Cheating a hair drug test is quite difficult, hence, the results tend to be more reliable.
• Historical insight: It reveals a pattern of substance use over time, unlike just recent usage.

Limitations:

• Recent consumption is undetectable: It takes roughly 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug testing is typically pricier compared to other testing methods.
• Results variability: Aspects like hair color and individual hair growth differences can influence the levels of drug metabolites.

Note: Although frequently termed "hair follicle tests," the analysis is done 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.
