Hair Follicle Drug Testing - Whiteville, LA

What it is, How it works

Hair analysis is widely regarded as an effective method for identifying drug and alcohol consumption. It captures long-term evidence of substance use by embedding biomarkers in the strands of the growing hair. When cut close to the scalp, this method offers a detection span of up to three months for alcohol and drugs. The collection process is straightforward, with resistance to tampering, and facilitates easy shipping.

A sample size of 1.5 inches comprising roughly 200 hair strands near the scalp totals approximately 100mg, which is the ideal amount for both screening and confirmation. However, for EtG, additional tests, and/or panels exceeding 10, a 150mg sample is suggested. It is advisable to measure the sample on a jeweler's scale. If scalp hair is not available, a comparable quantity of body hair is acceptable. We refer specifically to scalp hair in terms of head hair, while body hair includes all other types such as facial or axillary.

Process Overview

The laboratory procedure for evaluating drug test results encompasses four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial phase where a sample is integrated into a laboratory's system. This step ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not handled by an electronic chain of custody system.

Screening conducts a rapid preliminary check for substance abuse. Although it is an economical way to assess drug use in most samples, any positive screen necessitates confirmation for admissibility in legal settings. Samples that test presumptively positive during Screening must undergo further confirmation.

Should a sample test positive in the Screening process, more hair is extracted from the original specimen for the Extraction phase. Here, drug compounds are extracted at lower concentrations than those found in methods like urine or oral fluid tests, making hair drug screening particularly challenging to execute.

Confirmation of any positive screening result uses GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positives are cleansed before confirmation if needed. The comprehensive laboratory workflow, from Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair standards and the accreditation of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with their shorter detection period.
• Resistance to manipulation: Hair drug tests are hard to falsify, which enhances the accuracy of results.
• Historical insights: These tests can illustrate drug usage trends over extended durations, not merely recent consumption.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair after roughly 5-7 days.
• Higher expense: Hair drug tests are typically pricier than other drug testing techniques.
• Results variability: Elements like hair color and personal hair growth differences can alter drug metabolite concentration levels in the hair.

Note: While commonly labeled as "hair follicle tests," the analysis targets the hair strands and not the follicles beneath the skin.

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.
