Hair Follicle Drug Testing - Brewster, WA

What it is, How it works

Hair testing has increasingly been regarded as an effective means for identifying the use of drugs and alcohol. Hair retains a long-term record of alcohol and other drugs by embedding biomarkers in the strands of the growing hair. Hair taken near the scalp can offer an estimated 3-month detection period for alcohol and other substances. It's easy to collect, challenging to falsify, and simple to ship.

A sample of hair measuring 1.5 inches and consisting of about 200 strands (approximately the width of a #2 pencil) next to the scalp provides 100mg of hair, an ideal sample for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg is suggested. We suggest measuring the specimen using a jeweler’s scale. If scalp hair cannot be provided, an equal amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair pertains to all other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning consists of the preliminary process of entering a sample into a lab’s system. This entails verifying the sample's seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and inputting any extra data not included in an electronic chain of custody system.

Screening serves as an initial rapid examination for drugs of abuse. Although cost-effective for ruling out drug use in most samples, a positive screening necessitates confirmation for legal admissibility. Any samples considered presumptively positive during Screening must undergo secondary confirmation.

If a sample tests presumptively positive in Screening, additional hair is extracted from the initial specimen and readied for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than with other methods (such as urine or oral fluid), which is why hair drug testing is one of the most challenging methods to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS is used for confirmation of any positive screening result. All samples that test presumptive positive are washed, if necessary, prior to confirmation. The complete laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a shorter detection window.
• High accuracy: Cheating a hair drug test is extremely challenging, making outcomes more reliable.
• Historical usage data: It can reveal a pattern of drug use over time, not just recent activity.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to become detectable in hair.
• Higher cost: Hair drug tests tend to be more expensive than other drug testing methods.
• Variable results: Hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," the analysis is conducted on the hair strand, not on 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.
