Hair Follicle Drug Testing - King And Queen Court House, VA

What it is, How it works

The utilization of hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by imprisoning biomarkers within the fibers of the growing hair strand. Collected near the scalp, hair sampling can offer a detection span of up to roughly 90 days for alcohol and other drugs. Hair collection is straightforward, moderately resistant to tampering, and conveniently shipped.

A sample measuring 1.5 inches and comprising approximately 200 strands of hair (similar in dimension to a #2 pencil) taken nearest to the scalp will provide 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, or tests that exceed 10 panels, a 150mg specimen is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. When mentioning head hair, we refer solely to scalp hair. Body hair pertains to all other hair categories (such as facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a laboratory’s system. This involves confirming the proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from the electronic chain of custody system.

Screening consists of a preliminary swift check for drugs of abuse. Although it is an economical method to eliminate drug usage on most samples, a positive screening outcome requires confirmation to be valid in a legal context. Presumptively positive samples in Screening necessitate subsequent confirmation.

Should a sample be presumptively positive during Screening, further hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are drawn from hair at lower concentrations than with other methods (such as urine or oral fluid), thereby rendering hair drug screening especially challenging.

Confirmation of any positive screening findings is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are washed as required before confirmation. The complete laboratory process from Accessioning through Confirmation is subject to review under the CAP (College of American Pathologists) Hair certification and as per the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more limited detection period.
• Enhanced security: It is notably tough to manipulate the results of a hair drug test, thus enhancing their reliability.
• Historical insight: This method can reveal a pattern of drug consumption over an extended timeframe, rather than merely recent use.

Limitations:

• Lack of immediate detection: Drugs become detectable in hair approximately 5-7 days following use.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: Though frequently called "hair follicle tests", the analysis pertains to the hair strand and 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.
