Hair Follicle Drug Testing - Mojave, CA

What it is, How it works

Hair tests have gained recognition as a robust method for identifying drug and alcohol consumption. Hair captures long-term data of alcohol and other drug usage by preserving biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair may offer a detection window of up to around 90 days for alcohol and other drugs. Hair collection is straightforward, somewhat hard to tamper with, and convenient to transport.

A 1.5-inch sample of roughly 200 hair strands (about the width of a #2 pencil) nearest to the scalp provides 100mg of hair, the preferred specimen for both screening and confirmation. For EtG, additional panels, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. We suggest weighing the hair sample on a jeweler’s scale. In the case that scalp hair isn't accessible, equivalent body hair may be gathered. References to head hair signify scalp hair solely. Body hair denotes all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a sample within a lab’s system. This encompasses verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry not covered by an electronic chain of custody framework.

Screening constitutes an initial rapid assessment for drugs of misuse. While Screening is an economical method to eliminate drug usage in most samples, a positive screen must be validated for court acceptance. Samples presumed positive in Screening necessitate a secondary verification.

Should a sample be presumed positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are removed from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.

Verification of any positive results from Screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as needed. The comprehensive laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests, which have a briefer detection window.
• Hard to manipulate: Tampering with a hair drug test is particularly challenging, ensuring more accurate results.
• Offers historical insight: It can reveal a pattern of drug use over an extended duration, not solely recent consumption.

Limitations:

• Inability to detect recent use: It typically takes 5-7 days for drugs to become detectable in hair.
• Cost factor: Hair drug tests often incur higher costs compared to other drug testing techniques.
• Outcome variability: Elements such as hair color and individual differences in hair growth may influence drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests", the test itself examines the hair strand 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.
