Hair Follicle Drug Testing - Elk Mills, MD

What it is, How it works

Hair analysis has become recognized as an effective instrument for identifying substance and alcohol consumption. Hair offers a prolonged record of alcohol and other substances through the capture of biomarkers within the strands of growing hair. When samples are procured near the scalp, hair can offer roughly a 90-day detection span for alcohol and other substances. It is easy to gather, hard to tamper with, and convenient to transport.

A 1.5-inch length comprising roughly 200 hair strands (approximately resembling a #2 pencil's girth) nearest to the scalp equals 100mg of hair, the optimal sample amount for both screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the specimen is suggested. If scalp hair cannot be sourced, a comparable volume of body hair can be utilized. By head hair, we mean only scalp hair. Conversely, body hair pertains to all other types (e.g., facial, axillary).

Process Overview

The quartet of primary phases in the laboratory processing of a drug-test result includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary processing of a specimen into a lab's workflow. It encompasses ensuring the specimen was properly sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.

Screening pertains to an initial rapid detection for illicit drugs. Although Screening is an economical strategy to exclude drug presence in the bulk of samples, a positive result needs authentication to be valid in legal scenarios. Any samples tentatively positive in Screening necessitate further confirmation.

If a specimen tests potentially positive in Screening, more hair is gathered from the original sample and prepped for Extraction. At this phase, drugs are separated from hair at notably minute concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis as the most challenging technique.

Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation when necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized in accordance with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can disclose drug use for as long as 90 days, whereas urine tests offer a shorter detection duration.
• Challenging to manipulate: Cheating a hair drug test proves extremely difficult, enhancing result reliability.
• Traces usage history: It depicts a pattern of drug consumption over time, not merely recent use.

Limitations:

• Incapable of recent detection: Drugs require about 5-7 days to be traceable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug-testing approaches.
• Result disparities: Variables like hair pigmentation and individual differences in hair growth influence drug metabolite concentration in the hair.

Note: Although often termed "hair follicle tests", the analysis focuses on 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.
