Hair Follicle Drug Testing - Shawan, MD

What it is, How it works

Hair testing has emerged as an effective approach for identifying drug and alcohol consumption. The hair itself preserves a prolonged record of alcohol and other substances by capturing biomarkers within its expanding fibers. When taken near the scalp, hair offers up to about a 3-month detection timeframe for these substances. The hair collection process is straightforward, somewhat resistant to tampering, and easily transportable.

A 1.5-inch segment comprising around 200 hairs (comparable to the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred amount for analysis and verification. For EtG, extra assessments, and/or examinations over 10 panels, a 150mg specimen is advised. Utilizing a jeweler’s scale to measure the specimen is recommended. If scalp hair isn't obtainable, an equivalent quantity of body hair may be used. When referencing head hair, it pertains specifically to scalp hair. Body hair includes all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test outcome involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning stage, a sample is initially incorporated into a lab's system. This phase entails verifying the sample's secure sealing and proper shipment, assigning it a unique LAN (Laboratory Accessioning Number), and completing any missing data that isn't issued by an electronic chain of custody system.

Screening is a preliminary rapid test for drugs of abuse. Though it is a cost-efficient method to rule out substance use in most samples, a positive screening must be confirmed for it to be legally valid. Samples deemed presumptively positive in Screening will require further confirmation.

If a sample is suspected to be positive during the Screening phase, additional hair is taken from the primary specimen for the Extraction stage. At this point, drugs are extracted from hair at lower concentrations than in alternative methods (such as urine or oral fluid), which is why hair drug testing is the most challenging method to execute.

Any positive screening results undergo Confirmation through GC/MS, GC/MS/MS or LC/MS/MS. All samples with a presumptive positive outcome are washed if necessary before confirmation. The entire lab process, from Accessioning to Confirmation, is monitored under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can identify substance use for up to 90 days, whereas urine tests cover a shorter detection span.
• Tough to deceive: It is notably difficult to deceive a hair drug test, thus rendering the results more reliable.
• Offers historical insight: It can display a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Cannot identify recent use: It generally takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests usually carry a higher cost compared to other testing methods.
• Variability in outcomes: Elements like hair color and individual hair growth differences can influence the level of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests", the test examines the hair strand itself 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.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
