Hair Follicle Drug Testing - Churchville, MD

What it is, How it works

Interpreted as a robust instrument for discerning drug and alcohol consumption, hair testing captures extended histories by enclosing biomarkers within its growing strands. When snipped near the scalp, these strands unveil a detection span reaching nearly three months for both alcohol and various drugs. Hair collection is straightforward, holds a resistance to tampering, and facilitates easy transportation.

A segment measuring 1.5 inches, comprising roughly 200 strands (mirroring the size of a #2 pencil) adjacent to the scalp, yields about 100mg — the optimal mass for both screening and confirmation. For tests extending beyond 10 panels, EtG add-ons, or the like, 150mg of specimen is advised. It's recommended to utilize a jeweler’s scale for precise measurement. In situations where scalp hair is unavailable, an equivalent quantity of body hair may be harvested. It’s crucial to note that head hair references specifically scapular hair, whereas body hair encompasses all other types (such as facial or axillary).

Process Overview

The lab processing of drug test results incorporates four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the sample processing into the lab’s framework, ensuring the sample’s secure shipment and sealing, generating a random LAN (Laboratory Accessioning Number), and completing any requisite data entry absent in an electronic chain of custody system.

Screening acts as a preliminary examination for substances of abuse. Although cost-efficient, a positive outcome in this phase mandates verification for courtroom admissibility. Positively presumptive samples necessitate a secondary confirmation.

If the Screening suggests positivity, additional hair from the original sample proceeds to Extraction, where hair drugs are isolated at significantly reduced concentrations compared to other methods (such as urine or oral samples), presenting hair drug screening as the most challenging methodology to execute.

Positive screening validations occur through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all positively presumptive samples undergo a washing process if necessary. The entirety of lab operations from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair category alongside accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use up to 90 days, markedly longer than urine tests.
• Resistant to manipulation: Cheating is exceedingly challenging, enhancing accuracy.
• Historical insight: They offer a usage pattern over time instead of merely recent consumption.

Limitations:

• Immediate use detection deficiency: Drugs become traceable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing often incurs higher costs compared to other methods.
• Result variability: Factors such as hair pigmentation and individual growth factors can influence drug metabolite concentrations in hair.

Note: Though commonly termed as "hair follicle tests", the analysis concerns the hair strand itself, 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. 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.
