Hair Follicle Drug Testing - Powellville, MD

What it is, How it works

Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol consumption. Hair gives an extended overview of alcohol and drug usage by encapsulating biomarkers within its growing strands. When collected near the root, it can offer up to a three-month detection period for alcohol and drugs. Collection is straightforward, tampering is tough, and shipping is easy.

A 1.5-inch portion consisting of approximately 200 hair strands (about resembling the diameter of a #2 pencil) nearest to the scalp yields 100mg, the perfect sample size for analysis. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg is advisable. Using a jeweler's scale to weigh the specimen is recommended. If scalp hair can't be sourced, a similar volume of body hair may be used. Head hair refers exclusively to scalp hair, while body hair encompasses all other hair types (such as facial or axillary hair).

Process Overview

The core procedures in processing a drug test at a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is where a sample is initially entered into the lab's system. This step verifies the proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and completes any further data input missing from an electronic chain of custody system.

Screening conducts an initial rapid assessment for drug abuse traces. While it's a cost-effective way to exclude drug usage in most samples, positive findings need confirmation to be legally valid. Samples testing presumptive positive in Screening necessitate further verification.

Presumptive positive samples in Screening require additional hair from the original sample for Extraction. In this process, drugs are isolated from hair at much lower levels compared to other approaches (e.g., urine or oral fluids), making hair drug testing one of the most challenging methods.

Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before final confirmation if necessary. The complete lab procedure, from Accessioning to Confirmation, is audited under both CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, whereas urine tests have shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is very challenging, which enhances result reliability.
• Offers historical insight: It can show drug use patterns over an extended period, not just recent usage.

Limitations:

• No recent usage detection: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Variable results: Attributes like hair color and individual hair growth can influence drug metabolite concentration in hair.

Note: Widely called "hair follicle tests," these actually examine the hair strand, not the follicle under the skin.

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.
