Hair Follicle Drug Testing - Hardin, TX

What it is, How it works

Identified as an effective means of determining drug and alcohol consumption, hair testing utilizes the capture of biomarkers within the hair fiber as it grows, thus offering a comprehensive record of alcohol and drug usage over time. When hair samples are gathered near the scalp, they can reveal drug and alcohol use over a period of up to about 3 months. The procedure of collecting hair is user-friendly, difficult to falsify, and straightforward to transport.

A 1.5-inch hair sample, approximately 200 strands (equivalent to the thickness of a #2 pencil) taken closest to the scalp, will yield 100mg of hair, ideal for both screening and verification. For EtG screenings, additional tests, and/or panels exceeding 10, it is advisable to obtain 150mg of the sample. Utilizing a jeweler’s scale is recommended for weighing the specimen. If scalp hair cannot be acquired, an equivalent quantity of body hair can be used. References to head hair specifically mean scalp hair, while body hair denotes any other hair types (like facial or axillary hair).

Process Overview

Laboratory analysis of a drug test encompasses four vital steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the initial integration of the sample into the lab system occurs. This phase ensures the sample was properly sealed, assigned a random LAN (Laboratory Accessioning Number) for tracking, and that any missing data from an electronic chain of custody system is entered.

Screening serves as a preliminary examination for drug presence. Although Screening efficiently eliminates drug presence in most samples, positive results mandate further confirmation for legal proceedings. Samples that indicate a potential drug presence in the Screening phase necessitate additional confirmation.

Should Screening suggest drug presence, more hair is extracted from the original sample for the Extraction process. Here, drugs are isolated from hair at considerably lower concentrations than methods like urine or saliva testing, contributing to the inherent complexity of hair drug testing.

Verification of any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All possible positive samples undergo a cleansing process before confirmation as required. The exhaustive lab process, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair classification in addition to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug tests can identify substance use for a duration of up to 90 days, whereas urine tests have shorter detection spans.
• Hard to manipulate: Manipulating a hair drug test is significantly challenging, thus enhancing the reliability of results.
• Chronic usage insights: It offers insights into drug consumption patterns over time, rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only approximately 5-7 days following consumption.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Despite being commonly termed as "hair follicle tests", the analysis is performed on the hair strand and 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.
