Hair Follicle Drug Testing - Blanchard, PA

What it is, How it works

Seen as a potent tool, hair testing is effective in detecting drug and alcohol use. Offering a long-term record, hair captures biomarkers within its strands as it grows. When extracted near the scalp, hair shows a detection window of up to about three months for alcohol and drugs. It's easy to collect, challenging to tamper with, and straightforward to ship.

A 1.5-inch hair sample, roughly 200 strands (similar to a #2 pencil's thickness) nearest to the scalp, provides about 100mg of hair, ideal for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is suggested. Using a jeweler’s scale to weigh the specimen is advisable. If scalp hair isn't an option, equivalent body hair is acceptable. Head hair pertains to scalp hair alone. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning covers the sample's initial processing into a laboratory system, ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and filling out any extra data not entered by an electronic chain of custody system.

Screening consists of an initial swift check for drug abuse. Screening is a cost-effective method to discount drug usage in most samples. However, to be court-admissible, a positive screen needs confirmation. Any samples with a presumptive positive result during Screening require secondary confirmation.

In cases where a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. At this stage, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), underscoring why hair drug screening poses the greatest challenge methodologically.

Confirmation of any positive screening result uses GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests track drug use up to 90 days, in contrast to the shorter detection window of urine tests.
• Hard to deceive: Cheating a hair drug test is extremely difficult, ensuring more accurate results.
• Historical recount: It supplies a timeline of drug use over an extended period, beyond recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs become discernible in hair roughly 5-7 days post-use.
• Expense: Hair drug tests typically incur higher costs than other types of drug testing.
• Result variability: Elements like hair color and unique hair growth variations can impact drug metabolite concentrations in hair.

Note: Often called "hair follicle tests", the analysis is done on 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.
