Hair Follicle Drug Testing - Perry Hall, MD

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol use. The hair strands act as a timeline, capturing biomarkers of substances within their fibers as they grow. Samples taken near the scalp can offer a detection period of roughly three months for both alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and convenient to transport.

The ideal test sample consists of a 1.5-inch section of about 200 strands (similar in thickness to a #2 pencil) from near the scalp, totaling 100mg of hair for both screening and confirmation. For EtG tests, extra substances, or tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to use a jeweler’s scale to measure the specimen accurately. In cases where scalp hair is not accessible, body hair of equivalent mass can be used. 'Head hair' refers specifically to scalp hair, while 'body hair' encompasses any other type of hair (such as facial or axillary hair).

Process Overview

The drug test laboratory process consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within the lab's system. This step verifies proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any incomplete electronic data entry required for the chain of custody.

Screening is a preliminary method for quickly identifying drugs of abuse. While cost-efficient for eliminating drug usage in most samples, any positive results from Screening must undergo confirmation to be valid in legal settings. Presumptively positive results always require a follow-up confirmation test.

If Screening indicates a presumptive positive, additional hair from the original sample is prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other testing methods like urine or oral fluid, which underscores the complexity of hair drug screening.

Confirmation for a positive Screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples indicating a presumptive positive undergo necessary washing. The entire lab procedure, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can uncover drug use for up to 90 days, whereas urine tests offer a more limited detection timeframe.
• Difficulty to cheat: Cheating a hair drug test is exceptionally challenging, enhancing result reliability.
• Provides historical data: Capable of outlining a drug use pattern over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: Drugs become traceable in hair approximately 5-7 days following use.
• Cost: Generally, hair drug testing incurs more expenses than alternative methods.
• Variations in results: Drug metabolite concentration in hair can fluctuate due to factors like hair color and individual hair growth differences.

Note: Although commonly called "hair follicle tests", these tests evaluate the hair strand itself 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.
