Hair Follicle Drug Testing - Barton, MD

What it is, How it works

Hair analysis is widely recognized as an effective method for detecting drugs and alcohol usage. By capturing biomarkers within the strands of hair as they grow, hair can reveal a lengthy history of alcohol and drug consumption. When sourced close to the scalp, hair can offer a detection period extending up to three months for alcohol and drugs. It’s straightforward to collect, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch section consisting of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for screenings and confirmations. For EtG add-ons or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler's scale for weighing the sample. In case of absence of scalp hair, you can collect an equivalent amount of body hair. In our context, ‘head hair’ specifically refers to scalp hair only. 'Body hair' encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug testing outcomes consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial intake of a sample into a lab's system, ensuring it was properly secured and transported, generating a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.

Screening is an initial examination for abuse substances. Though Screening is economical for excluding drug usage in most samples, a positive screening result must be confirmed to be court-admissible. Presumptive positive samples in Screening necessitate a secondary confirmation.

Should a sample be deemed presumptively positive during Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are retrieved from hair at lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Any positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation, if required. From Accessioning to Confirmation, the entire lab process is examined under both the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use up to 90 days, unlike urine tests with shorter detection spans.
• Cheating prevention: Cheating a hair drug test is challenging, increasing the accuracy of results.
• Historical insight: It reveals a drug use pattern over time, not just recent use.

Limitations:

• Recent usage undetectable: Drugs typically become detectable in hair within 5-7 days.
• Expense: Generally, hair drug tests are costlier than alternate testing methods.
• Result inconsistency: Hair color and individual hair growth variations can impact drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the test analyzes 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. 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.
