Hair Follicle Drug Testing - Hurlock, MD

What it is, How it works

Hair examinations have emerged as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers in the strands as they grow. When harvested near the scalp, hair can offer up to roughly a 3-month window to detect alcohol and drugs. Hair is easy to gather, relatively hard to tamper with, and simple to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is ideal for both initial screening and confirmation processes. For EtG, enhancements, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair indicates all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial step that integrates a sample into a lab's system. This verifies that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and concludes any remaining data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for potential drug abuse. Although Screening is cost-efficient for eliminating drug usage in most samples, a positive screen must be verified to be considered valid in legal settings. Any sample that tests presumptively positive in Screening necessitates further confirmation.

If a sample tests as a presumptive positive during Screening, additional hair is extracted and prepped for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug testing processes.

Confirmation of a positive screen result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation if needed. The entire laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests which offer a shorter detection timeframe.
• Cheat-proof: Hair drug tests are challenging to deceive, resulting in more precise outcomes.
• Offers historical insights: It provides a timeline of drug use over an extended period, not just recent activity.

Limitations:

• Unable to detect recent use: Drugs take roughly 5-7 days to become noticeable in hair.
• Expense: Hair drug testing tends to be costlier than other testing options.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the levels of drug metabolites found in hair.

Note: Though often described as "hair follicle tests", the analysis encompasses the hair strand, 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.
