Hair Follicle Drug Testing - Pineville, LA

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair strands offer a prolonged record of alcohol and drug presence by capturing biomarkers within the fibers of the developing hair. When obtained from near the scalp, hair can provide an approximate 3-month window for detecting alcohol and drugs. Hair is easy to collect, moderately resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (equivalent to a #2 pencil width) nearest to the scalp yields 100mg of hair, which is optimal for screening and verification. For enhanced tests like EtG, or those exceeding 10 panels, 150mg of the sample is suggested. Employ a jeweler’s scale for specimen weighing. In the absence of scalp hair, a comparable quantity of body hair can be used. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses other variants (facial, axillary, etc.).

Process Overview

The laboratory drug test processing involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is processed into the lab system. It includes ensuring the sample was correctly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and finalizing any missed data entry not covered by an electronic chain of custody setup.

Screening is a preliminary method to check for substance misuse. While it is a cost-efficient approach to exclude drug use in most cases, a positive screening result must be confirmed for legal acceptability. Samples that test presumptively positive in Screening require an additional confirmation.

In the event of a presumptive positive result during Screening, further hair is extracted from the original sample and set for Extraction. In this phase, drugs are isolated from hair at a markedly decreased concentration compared to other techniques (e.g., urine or saliva), making hair drug analysis one of the most challenging to execute.

GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive screening outcomes. Presumptive positive samples undergo washing before confirmation as required. The entire lab process, from Accessioning to Confirmation, is audited under the CAP (College of American Pathologists) Hair guidelines and adheres to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair analysis can reveal drug usage up to 90 days, surpassing the shorter detection span of urine tests.
• Difficult to manipulate: Altering hair drug test results is challenging, ensuing more reliable outcomes.
• Historical usage pattern: Offers insight into the drug use trend over an extended timeline, unlike just recent usage.

Limitations:

• Lacks recent use detection: Approximately 5-7 days are required before drugs become traceable in hair.
• Expense: Hair drug analysis tends to be pricier than other testing methods.
• Result variability: Factors such as individual hair color and growth differences may influence drug metabolite concentrations in the hair.

Note: Despite the common term "hair follicle tests", the analysis is of the hair strand itself, not 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.

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.
