Hair Follicle Drug Testing - Zapata, TX

What it is, How it works

Hair testing is now recognized as an effective means for detecting drug and alcohol usage. Hair offers a historical record of alcohol and substance use by capturing biomarkers in the growing hair strand's fibers. When collected near the scalp, hair can provide an approximately 3-month detection period for alcohol and other drugs. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.

A sample measuring 1.5 inches and consisting of about 200 hair strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be used. When discussing head hair, we refer specifically to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a laboratory's database. It involves confirming the sample's secure sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.

Screening provides a preliminary assessment for drug presence. Although Screening efficiently excludes drug usage in most samples, a positive finding requires confirmation to be legally valid. Samples testing presumptive positive in Screening demand subsequent confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are extracted from hair at considerably lower concentrations than with alternate methodologies (such as urine or oral fluid), which contributes to the complexity of hair drug screening.

Confirmation for any positive Screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use up to 90 days, unlike urine tests which have limited detection periods.
• Challenging to circumvent: Cheating on a hair drug test is extremely challenging, enhancing accuracy.
• Historical insight: It reveals the drug use pattern over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Generally, hair drug tests cost more than alternative drug testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Although termed "hair follicle tests", this test evaluates the hair strand and not the underlying hair follicle

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.
