Hair Follicle Drug Testing - Rio Vista, TX

What it is, How it works

Hair analysis has emerged as an effective method for spotting drug and alcohol usage. Hair offers a longitudinal record of alcohol and drugs by encapsulating biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal up to an approximately three-month period for alcohol and drug detection. Hair collection is straightforward, challenging to tamper with, and simple to send.

A sample of 1.5 inches of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or tests over 10 panels, 150mg of hair is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair can be obtained. When mentioning head hair, it only refers to scalp hair. Body hair indicates all other types of hair (such as facial or axillary hair).

Process Overview

The primary steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial handling of a sample in the laboratory’s system. This involves checking that the sample was sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data input not provided by an electronic chain of custody.

Screening consists of an initial rapid assessment for drugs. Although it is a cost-efficient way to exclude drug use in most samples, a positive screening result must be verified for court acceptance. Any samples that test positive during Screening require follow-up confirmation.

If Screening suggests a positive result, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at much lower levels than in other approaches (such as urine or oral fluid), thus making hair drug testing the most complex to perform.

Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as positive undergo a washing phase before confirmation, if necessary. The laboratory's complete process, from Accessioning to Confirmation, complies with the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with shorter detection times.
• Hard to manipulate: It is extremely challenging to deceive a hair drug test, improving the accuracy of results.
• Provides usage trends: Offers a timeline of drug consumption, rather than just recent usage.

Limitations:

• Unable to spot immediate use: Drugs can take about 5-7 days to be identifiable in hair.
• Expense: Hair drug tests tend to be pricier than other drug test methods.
• Result variability: Elements such as hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Often labeled as "hair follicle tests", the examination is performed on the hair strand, 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. 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
