Hair Follicle Drug Testing - Whiteville, NC

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance use, such as drugs and alcohol. It captures extended histories of substance use by preserving biomarkers within the hair's fibers as they grow. Hair taken from near the scalp typically offers a detection range of up to three months for substances like alcohol and drugs. It is straightforward to gather, challenging to tamper with, and convenient for transportation.

A segment of 1.5 inches of hair, consisting of roughly 200 strands (around the diameter of a #2 pencil), closest to the scalp provides about 100mg of hair, which is the optimal amount for both initial analysis and verification. For EtG, additional tests, or screens surpassing 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing the sample is recommended. If scalp hair is not available, a comparable quantity of body hair may be utilized instead. When mentioning head hair, this specifically refers to scalp hair; body hair includes other types such as facial and axillary hair.

Process Overview

The core processes in the lab analysis of drug test results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary procedure of integrating a sample into the lab’s system. This involves checking if the sample is properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not handled by an electronic chain of custody.

Screening is a preliminary assessment for substance use. Although Screening is an economical method to assess drug absence in most samples, any positive result must be confirmed for legal admissibility. Samples exhibiting a presumptive positive in Screening require further confirmation.

Should a presumptive positive arise during Screening, further hair is extracted from the initial sample to prepare it for Extraction. This involves drugs being extracted from hair in much lower concentrations compared to other techniques (e.g., urine or oral fluid), rendering hair drug screening as the most complex technique.

Verification of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed as needed before Confirmation. The complete lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair standard and compliance with ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug analysis can track drug use over 90 days, unlike urine tests, which have a shorter range.
• Hard to falsify: Cheating on a hair drug test is very tough, hence ensuring more reliability in the results.
• Reveals usage patterns: It shows usage trends over time, rather than just recent consumption.

Limitations:

• Recent use undetectable: It usually takes about 5-7 days for drugs to appear in hair samples.
• Expense: Hair drug testing is typically pricier than other testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence the levels of drug metabolites in the hair.

Note: Commonly called "hair follicle tests", the analysis actually evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Whiteville, NC

Hair follicle testing provides a distinctive edge over traditional urine tests by offering superior 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.
