Hair Follicle Drug Testing - Richmond Highlands, WA

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol use. Hair offers a long-term record of alcohol and drug intake by capturing biomarkers within the strands as they grow. When cut near the scalp, hair can present up to a three-month timeframe for detecting drugs and alcohol. The collection of hair is straightforward, relatively hard to tamper with, and convenient to send.

A sample of 1.5 inches, made up of approximately 200 strands of hair (around the girth of a #2 pencil) nearest to the scalp, will yield 100mg, which is the optimal sample size for both screening and confirmation purposes. For tests such as EtG, additional screenings, or those exceeding 10 panels, a 150mg sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair cannot be collected, a similar quantity of body hair is acceptable. When mentioning head hair, it specifically refers to scalp hair. The term body hair encompasses all other types of hair (such as facial hair, axillary hair, etc.).

Process Overview

The principal stages in the lab analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample within a lab’s framework. This process verifies if the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any additional information missing from an electronic chain of custody system.

Screening entails a preliminary rapid assessment for the presence of drugs. Though Screening is a cost-efficient method to dismiss the presence of drugs in most samples, a positive screen necessitates confirmation to be valid legally. Samples presumed positive in Screening must undergo another level of confirmation.

If a sample tests presumptively positive during the Screening phase, additional hair is taken from the original specimen and readied for Extraction. At this point, drugs are drawn from hair at concentrations significantly lower than those detected in other methods (such as urine or oral fluid), which justifies the complexity in conducting hair drug screening.

Confirmation of any positive screen is carried out employing GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumed positive samples undergo a wash before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and is certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Not easily manipulated: Cheating a hair drug test is quite challenging, thus ensuring more reliable outcomes.
• Offers historical insight: It can depict a pattern of drug intake across a timeline, not merely reflecting recent usage.

Limitations:

• Ineffective for recent use: It requires around 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing approaches.
• Result variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although often called "hair follicle tests," the analysis is conducted 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.
