Hair Follicle Drug Testing - Olney, MD

What it is, How it works

Hair testing has emerged as an effective approach for unveiling drug and alcohol consumption. Hair embodies a prolonged account of drug and alcohol usage by ensnaring biomarkers within the strands of the progressing hair shaft. When procured near the scalp, hair can reveal a detection span of up to roughly three months for both alcohol and drugs. Hair is uncomplicated to gather, relatively challenging to tamper with, and straightforward to dispatch.

A sample of 1.5 inches, consisting of roughly 200 hair strands (approximate thickness of a #2 pencil) nearest to the scalp, equates to 100mg, which is the optimal sample for both screening and confirmation. For EtG tests, add-ons, or assessments exceeding 10 panels, a 150mg sample of the hair is advised. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent measure of body hair may be utilized. Referring to head hair pertains solely to scalp hair. Body hair designates all other hair types (facial, axillary, etc.).

Process Overview

The quartet of primary stages within the laboratory handling of a drug test result includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the primary processing of a sample into a laboratory’s structure. This involves affirming that the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody framework.

Screening encompasses an initial expedient examination for drugs of misuse. While Screening is a cost-efficient means of ruling out drug usage across the majority of samples, any positive screen must undergo confirmation to hold validity in legal settings. Samples arisen as presumptively positive in Screening necessitate subsequent confirmation.

Should a sample surface as presumptively positive in the Screening phase, additional hair is obtained from the primary specimen and prepared for Extraction. In this phase, drugs are extracted from the hair at considerably lower concentrations than other techniques (such as urine or oral fluid), thereby rendering hair drug screening the most complex methodology to execute.

Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as deemed necessary. The exhaustive laboratory undertaking from Accessioning to Confirmation is examined under the auspices of both the CAP (College of American Pathologists) Hair certification and the accreditation according to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can unveil drug use for up to 90 days, in contrast to urine tests, which maintain a shorter detection span.
• Challenge to deceive: Cheating a hair drug test proves exceedingly difficult, thereby enhancing result accuracy.
• Presents historical insights: It provides a pattern of drug usage over time, rather than solely recent consumption.

Limitations:

• Incapable of detecting recent consumption: A period of roughly 5-7 days is necessary for drugs to become detectable in hair.
• Expense: Hair drug tests generally surpass other drug testing methodologies in cost.
• Variability in outcomes: Factors such as hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although frequently dubbed as "hair follicle tests," the test itself evaluates the hair strand rather than 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
