Hair Follicle Drug Testing - Wauhillau, OK

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It offers a prolonged history by embedding biomarkers within the fibers of the hair strand as it develops. When taken close to the scalp, hair can reveal usage for up to a 3-month period for alcohol and other substances. Its collection is straightforward, it’s somewhat resistant to tampering, and it's easy to send.

A 1.5-inch segment consisting of approximately 200 hair strands (around the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest weighing the specimen using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. When mentioning head hair, we specifically refer to scalp hair. Body hair includes other types like facial and axillary hair.

Process Overview

The laboratory processing of drug test results comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial processing into a lab’s system. This step includes checking that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any additional information not covered by an electronic chain of custody system.

Screening conducts a preliminary examination for drugs of abuse. While it is a cost-effective way to exclude drug use for most samples, a positive result requires confirmation to be valid in legal settings. Any samples testing presumptively positive during Screening require further confirmation.

If a sample tests presumptively positive during Screening, additional hair is prepared from the initial sample for Extraction. In this phase, drugs are extracted from hair at a lower concentration compared to other methods (like urine or oral fluid), making hair drug screening the most challenging technique.

Confirmation of positive Screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing positive are washed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is examined under CAP (College of American Pathologists) Hair and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests which detect for a shorter duration.
• Hard to manipulate: It is challenging to alter a hair drug test, ensuring greater accuracy in results.
• Historical insights: It can reveal patterns of drug usage over time, not just recent activity.

Limitations:

• Inability to detect recent use: It takes about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Aspects like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although often labeled as "hair follicle tests", the analysis focuses on the hair strand and not the hair 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.
