Hair Follicle Drug Testing - Mayfair, CA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substances by embedding biomarkers within the growing fiber strands. When collected near the scalp, hair can offer a detection window of up to approximately three months for alcohol and other substances. The collection of hair is straightforward, relatively hard to tamper with, and convenient for shipping.

A 1.5-inch segment consisting of about 200 hair strands (equivalent to the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal quantity for both initial screening and subsequent verification. For EtG, additional tests, or tests exceeding 10 panels, a specimen amounting to 150mg is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be collected. "Head hair" specifically refers to scalp hair only, while "body hair" includes all other types (such as facial and axillary hair).

Process Overview

The lab process for a drug test result comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into a lab’s system, which includes checking that the sample is sealed and shipped correctly, assigning it a unique LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody.

Screening serves as a preliminary evaluation for substance abuse. Although it is an economical method to eliminate drug usage in most samples, any positive screen must be verified to be legally valid. Samples that test positive during Screening require a follow-up confirmation.

Should a sample yield a positive result in Screening, additional hair is extracted from the original sample and processed for Extraction. In this phase, substances are extracted from the hair at a much lower concentration compared to other methods (such as urine or oral fluid), which makes hair drug testing the most complex method to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test positive are washed before confirmation as needed. The entire testing process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a span of up to 90 days, unlike urine tests that have a shorter detection timeframe.
• Higher resistance to tampering: It is exceedingly difficult to manipulate a hair drug test, resulting in more reliable results.
• Tracks usage over time: It reveals a history of drug use over time, rather than just recent use.

Limitations:

• Cannot reveal immediate usage: Drugs take approximately 5-7 days to appear in hair.
• Expense: Generally costlier than other methods of drug testing.
• Result variability: Aspects like hair color and individual differences in hair growth can influence the concentration of drug components in hair.

Note: Although commonly termed "hair follicle tests", the analysis focuses on the hair strands 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.

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.
