Hair Follicle Drug Testing - Queen, PA

What it is, How it works

Hair sampling is increasingly regarded as a valuable means for identifying alcohol and drug usage. Hair offers an extended retrospective view by trapping biomarkers within the fibers of the hair as it grows. When gathered close to the scalp, hair can reveal up to roughly a 3-month timeframe for alcohol and other substances. This collection method is easy to execute, hard to tamper with, and convenient to send.

An ideal sample is a 1.5-inch segment of roughly 200 hair strands (equivalent to a #2 pencil) nearest to the scalp, yielding 100mg of hair, suitable for evaluation and validation. For EtG, extra tests, or screenings beyond 10 panels, a specimen amount of 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, a comparable amount of body hair can be used. "Head hair" denotes scalp hair exclusively. "Body hair" includes all other hair types (such as facial or axillary).

Process Overview

The laboratory analysis of drug test results occurs in four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step, involving the integration of a sample into a lab's system. This step verifies the sample's seal and shipment, assigns a random LAN (Laboratory Accessioning Number), and fills in any necessary information not covered by an electronic chain of custody system.

Screening is a preliminary check for substances of abuse. It is a cost-efficient method to exclude drug usage in most samples, though a positive result must be authenticated for legal acceptability. Positive indications in Screening necessitate further verification.

Samples with a presumptive positive in Screening require more hair to be gathered from the initial specimen for Extraction. This stage isolates drugs from hair at lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug screening a more complex technique to execute.

Positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All positive results are cleansed prior to confirmation as necessitated. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair provisions and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection: Hair drug tests can reveal drug usage up to 90 days, whereas urine tests have a shorter detection duration.
• Resistance to tampering: It is extremely challenging to manipulate a hair drug test, ensuring more reliable results.
• Historical insight: It can show usage patterns over time, not just recent consumption.

Limitations:

• Unable to detect recent consumption: It takes around 5-7 days for drugs to show up in hair.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite concentrations in hair.

Note: Though commonly called "hair follicle tests", this test assesses the hair strand, not the follicle under 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.
