Hair Follicle Drug Testing - Lincolnville, SC

What it is, How it works

Hair screening is now recognized as an effective means to detect both drug and alcohol consumption. Hair retains a historical record of alcohol and drug use by encapsulating biomarkers within the strands of hair as it grows. When gathered near the root, hair can offer a detection period of up to around 90 days for drugs and alcohol. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A hair sample measuring 1.5 inches and consisting of approximately 200 strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, considered optimal for both screening and verification. For EtG, additional tests, or those extending beyond 10 panels, a specimen weighing 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be collected. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

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

Accessioning is the first step, integrating a sample into a laboratory’s workflow. This includes ensuring the sample is correctly sealed and transported, associating it with a specific LAN (Laboratory Accessioning Number), and completing additional data inputs absent from an electronic chain of custody system.

Screening is a preliminary straightforward evaluation for substances of misuse. Although Screening is an economical method to negate drug presence in most samples, a screen yielding a positive result must be validated for legal admissibility. Any presumed positive samples in Screening demand a secondary confirmation.

For samples presumed positive in the Screening phase, additional hair is taken from the initial sample for Extraction preparation. This phase involves the extraction of drugs from hair at significantly lower concentrations than alternative methods (such as urine or oral fluid), which is why hair drug screening presents the greatest challenge in terms of execution.

Any positive screening outcome is confirmed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo a wash before confirmation if necessary. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for as long as 90 days, unlike urine tests which have a much shorter detection timeframe.
• Challenge to falsify: Hair drug tests are notably difficult to tamper with, enhancing result accuracy.
• Tracks usage history: This method can reveal a trend of drug use over a span rather than just recent usage.

Limitations:

• Unable to detect recent use: Detection of drugs in hair requires approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result disparities: Variables such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: The term "hair follicle tests" is commonly used; however, the analysis involves the hair strand and not the hair 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.
