Hair Follicle Drug Testing - Alto, CA

What it is, How it works

Hair testing is recognized as an effective means for detecting drug and alcohol usage. It offers an extended history of substance use by retaining biomarkers within the strands of developing hair. When sourced near the scalp, hair can offer a detection timeframe of up to nearly 3 months for alcohol and substances. Hair is uncomplicated to gather, relatively resistant to tampering, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable in width to a #2 pencil) near the scalp provides 100mg of hair, which is the optimal sample for assessment and validation. For EtG, additional tests, and panels beyond 10, 150mg of the sample is advised. We advocate for measuring the specimen on a jeweler’s scale. If scalp hair is insufficient, an equivalent amount of body hair can be collected. "Head hair" specifies scalp hair only. "Body hair" denotes all other types of hair (e.g., facial, axillary).

Process Overview

The primary steps in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of entering a sample into a lab system. This step ensures that the sample was correctly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data input not handled by an electronic chain of custody system.

Screening is an initial, rapid check for substances of abuse. While Screening is a budget-friendly method to negate substance use in most samples, a positive result must be verified to be legally admissible. Any samples that are tentatively positive during Screening necessitate further confirmation.

If a sample shows tentative positivity in the Screening phase, more hair is taken from the original sample and prepped for Extraction. In this phase, drugs are taken from the hair at a lower concentration than in other methods (e.g., urine or oral fluid), making hair drug analysis one of the more challenging methodologies to conduct.

Confirmation of any positive screening is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples are cleansed before confirmation if required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use as far back as 90 days, whereas urine tests have a more limited detection timeframe.
• Difficult to manipulate: It's notably challenging to compromise a hair drug test, enhancing result precision.
• Offers historical insight: It gives a pattern of substance use over a duration, not merely recent usage.

Limitations:

• Incapable of detecting recent usage: It typically takes 5-7 days for substances to be noticeable in hair.
• Expense: Hair drug tests tend to be pricier than other substance testing techniques.
• Result variance: Elements such as hair color and personal differences in hair growth can influence the level of drug metabolites in the hair.

Note: Although often termed as "hair follicle tests", the examination actually assesses the hair strand and not the 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.
