Hair Follicle Drug Testing - Stratford, CA

What it is, How it works

Hair testing is recognized increasingly as an effective method for identifying drug and alcohol consumption. Hair serves as a chronic record of alcohol and other drugs, capturing biomarkers within the strands as they grow. When hair samples are taken near the scalp, they can reveal drug and alcohol use over a detection period of up to roughly three months. Collection is straightforward, tampering is relatively challenging, and shipping is convenient.

A hair sample measuring 1.5 inches, comprising approximately 200 strands (akin to a #2 pencil's width) nearest to the scalp, yields 100mg, which is perfect for screening and verification. In cases involving EtG, additional tests, or panels exceeding 10, a specimen of 150mg is suggested. We advise using a jeweler’s scale for specimen measurement. If scalp hair isn't available, a similar mass of body hair can be used. Note that "head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other types, like facial or axillary hair.

Process Overview

The drug test laboratory procedure incorporates four central steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial phase, integrating a sample into the lab's database. This includes confirming the sample's proper sealing and shipment, issuing a random LAN (Laboratory Accessioning Number), and entering any additional data not provided by an electronic chain of custody system.

Screening is a preliminary assessment targeting drugs of abuse. Despite Screening's cost-efficiency for eliminating drug use in most samples, positive results must be validated to hold legal weight. Presumptive positive samples in Screening require further verification.

When a sample tests presumptively positive during Screening, additional hair is extracted from the primary specimen and readied for Extraction. At this point, drugs are isolated from hair at concentrations markedly lower than those in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as necessary. The comprehensive lab process, from Accessioning through Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests trace drug use over 90 days, unlike the shorter detection span of urine tests.
• Cheat-resistant: Compromising a hair drug test is tough, ensuring more precise results.
• Chronological data: It demonstrates a pattern of drug consumption over time, rather than only recent usage.

Limitations:

• Cannot indicate recent consumption: Drugs typically need 5-7 days post-use to become detectable in hair.
• Expense: Hair drug tests usually command higher costs than other methods.
• Result variability: Factors like hair color and personal hair growth variations contribute to fluctuating drug metabolite concentrations in hair.

Note: Referred to at times as "hair follicle tests," the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing Why Hair Follicle Testing Beats Urine Testing in Stratford, CA, hair analysis emerges superior in both detection accuracy and reliability. Unlike traditional urine tests, hair follicle testing has a much longer detection window, capturing drug use over several months rather than days.

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.
