Hair Follicle Drug Testing - Oklaunion, TX

What it is, How it works

Recognized as a powerful method for identifying drug and alcohol consumption, hair analysis offers a prolonged history of substance use by capturing biomarkers in the fibers of the growing hair strand. When collected near the scalp, hair can provide up to around a 3-month detection window for alcohol and other substances. Hair is easy to gather, somewhat hard to tamper with, and simple to send.

A 1.5-inch segment of approximately 200 strands of hair (comparable in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or tests above 10 panels, a 150mg specimen is suggested. Utilizing a jeweler’s scale to weigh the sample is recommended. If scalp hair is absent, a similar quantity of body hair can be collected. "Head hair" specifically refers to scalp hair. "Body hair" denotes all other hair types (facial, axillary, etc.).

Process Overview

The key steps involved in the laboratory analysis of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a laboratory’s system. This includes checking that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not provided by an electronic chain of custody system.

Screening includes an initial rapid check for drugs of abuse. While Screening is cost-efficient for ruling out drug use in most samples, a positive screen must be verified for court admissibility. Any samples presumptively positive in Screening necessitate secondary confirmation.

If a sample appears presumptively positive in Screening, more hair is taken from the initial specimen and set for Extraction. In Extraction, drugs are extracted from hair at a much lower concentration compared to other methods (ex. urine or oral fluid), which is why hair drug screening presents the most challenging methodology to execute.

Confirmation of any positive screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The comprehensive laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, compared to urine tests which offer a shorter detection window.
• Difficulty to cheat: Cheating a hair drug test is notably difficult, enhancing the accuracy of results.
• Provides historical data: It reveals a pattern of drug use over an extended period, rather than just recent use.

Limitations:

• Cannot detect recent use: Detection in hair takes approximately 5-7 days post drug use.
• Cost: Hair drug tests tend to be pricier than alternative testing methods.
• Variations in results: Factors such as hair color and individual differences in hair growth can influence the concentration of drug byproducts in hair.

Note: Commonly called "hair follicle tests", the test examines the hair strand rather than 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.
