Hair Follicle Drug Testing - Oxbow Estates, AZ

What it is, How it works

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of hair as it grows, hair can chronicle long-term substance use. When snipped close to the scalp, it can reveal usage over a span of nearly 90 days for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to mail.

A hair sample measuring about 1.5 inches with 200 strands (similar in girth to a #2 pencil), when cut nearest to the scalp, yields approximately 100mg, the preferred amount for both screening and confirmation. For EtG, additional panels, or tests beyond 10 panels, it is advisable to gather 150mg. Utilizing a jeweler's scale for weighing is recommended. In the absence of scalp hair, a comparable quantity of body hair can be gathered. References to head hair pertain exclusively to scalp hair, whereas body hair includes all other types (e.g., facial, axillary).

Process Overview

The laboratory drug test process consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial phase where a sample is processed into a lab’s system. This step ensures the sample is correctly sealed and shipped, assigns it a random LAN (Laboratory Accessioning Number), and addresses any additional data entry not captured via an electronic chain of custody system.

Screening involves a preliminary check for substances of abuse. Although Screening offers a cost-efficient method to exclude drug use in most samples, any positive results must be verified to be considered legally valid. Samples with preliminary positive results in Screening require further confirmation.

If Screening indicates a potential positive, more hair is extracted from the original batch for the Extraction stage. During Extraction, drug substances are isolated from hair at significantly lower concentrations than in other testing forms (e.g., urine or saliva), rendering hair screening more complex.

Positive Screening outcomes are substantiated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to Confirmation as necessary. Each phase, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation requirements.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for as long as 90 days, as opposed to the shorter durations characteristic of urine tests.
• Resistance to manipulation: Manipulating a hair drug test is exceedingly difficult, ensuring more reliable results.
• Historical substance use insights: It can map drug use patterns over time, rather than pinpointing only recent usage.

Limitations:

• Incapable of detecting immediate use: Drugs take roughly 5-7 days to manifest in hair.
• Cost implications: Hair drug tests tend to be pricier compared to other testing techniques.
• Result variability: Elements such as hair coloration and individual hair growth differences can influence drug metabolite concentrations in hair samples.

Note: Although commonly called "hair follicle tests", the assessment is performed on the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Oxbow Estates, AZ, hair follicle testing is preferred over traditional urine testing due to its superior detection accuracy and reliability.

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.
