Hair Follicle Drug Testing - Accokeek, MD

What it is, How it works

Hair examination has become recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by encapsulating biomarkers within the fibers of the growing strand. When a sample is taken nearest to the scalp, it can provide an approximate 3-month window of detection for alcohol and drug use. Hair is straightforward to collect, relatively challenging to tamper with, and convenient to send.

A 1.5-inch segment comprising around 200 hair strands (akin to the girth of a #2 pencil) nearest the scalp provides 100mg of hair, making it the optimal amount for analysis and verification. For tests such as EtG, add-ons, or those surpassing 10 panels, 150mg of sample is advisable. Using a jeweler’s scale is suggested for weighing. In the absence of head hair, a similar quantity of body hair may be harvested. When mentioning head hair, we mean solely scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial phase of inputting a sample into the lab’s system. This step ensures the sample's proper sealing and shipping, assigns it a random LAN (Laboratory Accessioning Number), and finalizes any absent data entry not already supplied by an electronic chain of custody system.

Screening consists of an initial rapid assessment for drugs of misuse. Although Screening is an economical tool for ruling out drug use in most samples, a positive screen requires confirmation for legal acceptability. Samples that yield a presumptively positive in Screening need a follow-up confirmation.

Should a specimen show a presumptive positive during the Screening phase, additional hair is extracted from the primary sample and made ready for Extraction. In this phase, the extraction of drugs from hair occurs at concentrations significantly lower than in other methods (such as urine or oral fluid), hence why hair drug screening is intricate to perform.

Confirmation of any positive screening outcomes is achieved using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation if necessary. The entire lab procedure from Accessioning through Confirmation is conducted in adherence to both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use up to 90 days, whereas urine tests have a briefer detection period.
• High resistance to tampering: Tampering with a hair drug test is extremely difficult, enhancing result precision.
• Historically informative: Offers insights into drug usage patterns over time rather than just recent activity.

Limitations:

• Cannot pinpoint recent use: It requires about 5-7 days post-drug use for detection in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Differences in hair color and individual growth rates can influence the levels of drug metabolites within the hair.

Note: Commonly termed as "hair follicle tests," these tests actually analyze the hair shaft and 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.
