Hair Follicle Drug Testing - Menlo Park, CA

What it is, How it works

Hair testing has gained prominence as an influential method for detecting alcohol and drug consumption. Hair offers an extended historical record of substance use by embedding biomarkers within the strands' fibers as they grow. When acquired near the scalp, it can detect substances up to a three-month period for both alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and easy to send.

A sample measuring 1.5 inches consisting of about 200 hair strands (approximately akin to a #2 pencil) nearest to the scalp yields about 100mg of hair, which is optimal for testing and verification. For EtG, supplemental tests, and/or testing beyond 10 panels, a 150mg sample is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair is acceptable. When we mention head hair, we are exclusively referring to scalp hair. Body hair includes any other hair types (such as facial, axillary, etc.).

Process Overview

Drug testing in a laboratory involves four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the beginning of processing a sample within a laboratory's system. This procedure ensures that the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any supplementary data entry not managed by an electronic custody chain.

Screening is an initial, rapid assessment for substance abuse. Although economical for excluding drug usage in most samples, a positive finding in Screening must be substantiated for legal proceedings. Samples indicating presumptive positivity in Screening require further confirmation.

Should a sample show presumptive positivity during the Screening, additional hair from the primary sample is extracted for further analysis. During Extraction, substances are obtained from hair at much lower concentrations in comparison to other techniques (such as urine or oral fluid), highlighting why hair drug testing is among the most challenging methodologies.

Confirming any positive results from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicating presumptive positivity undergo washing before confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, whereas urine tests present a shorter detection span.
• Resistant to tampering: Hair drug tests are remarkably difficult to manipulate, ensuring higher result accuracy.
• Historical analysis: It provides a chronological pattern of drug consumption over an extended timeframe, not merely recent activity.

Limitations:

• Unable to detect recent usage: It generally requires 5-7 days for substances to become detectable in hair.
• Expense: Compared to other drug testing techniques, hair drug tests are usually pricier.
• Result variations: Factors like hair color and personal hair growth differences can impact drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the actual analysis targets the hair strand, excluding 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.
