Hair Follicle Drug Testing - Belltown, CA

What it is, How it works

Hair testing has become recognized as a significant method for identifying the use of drugs and alcohol. Hair offers an extended timeline for alcohol and drug detection by encasing biomarkers within the hair strand's fibers as it grows. When acquired near the scalp, hair can offer a detection period extending up to roughly three months for alcohol and drugs. The collection of hair is easy, relatively hard to tamper with, and simple for transportation.

A 1.5-inch segment of roughly 200 hair strands (equivalent to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is suggested. We advocate for using a jeweler’s scale for weighing the sample. If scalp hair isn’t available, an equal quantity of body hair might be used. When we mention head hair, it specifically refers to scalp hair. Conversely, body hair encompasses other kinds of hair (beard, armpit, etc.).

Process Overview

The principal four stages in the laboratory handling of a drug testing result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the primary processing of a sample into a lab's system. This step involves checking whether samples were correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any other data entry omitted by an electronic chain of custody system.

Screening involves an initial swift evaluation for drug abuse indicators. While Screening provides an economical approach to dismiss drug usage in most samples, a positive screen must be validated to be legally viable. Samples flagged as presumptively positive in Screening do require a further confirmation.

When a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. At this stage, drugs are drawn from hair at a notably lower concentration compared to other methods (like urine or saliva), which makes hair drug testing the most complex method to conduct.

Any positive screening outcome is validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive are cleansed before confirmation as necessary. The entire laboratory operation from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation guidelines.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug testing can determine drug usage for as long as 90 days, whereas urine tests provide a shorter detection period.
• Difficulty of manipulation: Manipulating a hair drug test is extremely challenging, which ensures more accurate results.
• Provides past data: It may indicate a recurring pattern of drug use over time, rather than merely recent use.

Limitations:

• Inability to detect recent consumption: It typically requires 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests tend to be costlier than alternative drug testing techniques.
• Variability in results: Aspects such as hair pigmentation and individual differences in hair growth can influence the concentration of drugs in the hair.

Note: Although frequently called “hair follicle tests,” the test itself assesses the hair strand, 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.
